It’s the same for me. I turn on the second one with force, but I don’t see the point in turning on the first one on the go. The engine runs fine at low speeds.

Synchronizers 1 and 2 are covered, I also turn on the first one at low speed - neutral - gas - clutch, the first one is like on a truck. and from 3rd to 2nd with transfer (but not on the clutch, but through the neutral gearbox!).

Was 3110 2000. Same behavior of the box. Only the second one is more or less normal. turned on. The first one did not turn on at all while driving. Now 31105 2004 The gears turn on normally. The first one turns on tighter while moving.

My father has the same problem on the Volga. Gas 24, the box is plugged in from 31st 5st. So the first one turns on only when the car is stationary; if you start moving, you can’t turn on the first one. The second one sticks in sooo hard, you have to sweat, nothing crunches, it just fits in very tight. The rest of the gears are like clockwork, and second and first cannot be engaged either. This is a CAT disease, and specifically stage 5. With 4speed this is not observed, everything turns on like clockwork)

When the speed of the car begins to turn on heavily, it not only causes an unpleasant feeling, but also makes the operation of the car unsafe. In this article we will analyze the reasons why gears are difficult to engage or do not shift at all, which is usually associated with this.

The gearbox is a complex mechanism that requires constant maintenance. Including regular diagnostics and gearbox oil changes. Ignoring these measures often leads to problems with gear shifting.

About the problems of the Gazelle Next checkpoint and options for solving or preventing them

It would seem that after a quarter of a century of its quite successful existence, GAZelle should have gotten rid of all its “diseases”, not only “children’s” ones, but also completely “adult” ones.

Look, the “new generation”, which is “Next”, can no longer be called new, and there are rumors that AvtoGAZ is actively working on the next promising model.

In general, the design of the car is sufficiently mature so as not to cause any special problems for owners and drivers, but such an important unit as the gearbox still sometimes causes very serious complaints from many.

What are the reasons for poor gear shifting?

Difficulty shifting gears can occur as a result of improper operation of the gearbox, or due to operation of the vehicle on bad roads. Problems with the gearbox sooner or later occur in used cars.

If you have difficulties when trying to switch to another gear, you cannot shift or it takes a lot of effort, then there is clearly a malfunction. Most often, car owners turn to a car service center when they have difficulty engaging first gear or reverse gear . A fairly common problem on VAZ and Ford Focus cars.

Let's look at the faults that lead to difficult gear shifting:

• Clutch malfunction. In this situation, the gears will engage either poorly or not completely. A common occurrence in VAZ cars that have fur cables. the clutch is moving away from the mount.
• Problems in the drive of the switching mechanism. Broken traction leads to difficult engagement of 1st and reverse gears.
• The jet thrust is faulty.
• Wear of plastic parts in the box control drive.
• The slide is incorrectly positioned. A weighty element, incorrect adjustment leads to malfunctions.
• Bearing wear. This is a fairly rare occurrence; anyone can experience this, especially when you have a manual transmission. In such a situation, it is usually difficult to engage first gear.
• The box shaft is faulty. By itself, it is not subject to heavy loads, which could lead to wear. A factory defect may cause the entire unit to be replaced.
• Clutch failure. Often found among owners of cars with an automatic transmission. The malfunction is eliminated by replacing the clutches.
• Faulty synchronizers are the most common problem among gearbox breakdowns. They are made of brass, and this metal itself is quite soft. During use, it wears out and wears out. The breakdown is usually accompanied by a grinding noise when switching to another speed.

The box turns off and the gear falls out

If the speeds are off, the culprit may be the fork, clutch, or worn transmission gears.
It happens that the spring that presses the fixation ball bursts. It is also possible that the input shaft splines may dry out. The reason may be the bronze crackers on the third and fourth gear forks - they break in half. It is also possible that burrs may form on the locking device. Many defective parts are installed on the Gazelle gearbox right from the factory. For example, blocking rings, which must have a gap of at least 0.3 mm. In fact, there are many such elements with a gap of 0.1-2.5 mm.

Why is it difficult to engage manual transmission gears?

manual gear shifting

• The most common problem is clutch failure. In such a situation, reverse gear turns on with a bang. This happens because the gear overlaps the tooth. Reverse speed is the only gear in the box that does not have synchronizers. For this reason, clutch failure is so obvious on it.
• The second reason is a defect in the mechanism responsible for selecting the gear. This breakdown occurs when the car is stationary and you try to shift into gear.
• The third is severe wear of the gearbox synchronizers. Mostly, breakdowns occur with those that are most often used. These are first, second and third gear. Severe wear of the synchronizers only appears when switching while driving.

To prevent possible gearbox malfunctions, perform regular maintenance, change the oil on time, and in case of minor failures, rush for diagnostics . This will save you time and money in the future.

What to do if it is difficult to engage reverse gear?

If you have difficulty engaging reverse gear, do one of the following :

1. When you feel that the gear has not reached the end, release the clutch slightly, and the gear will be inserted all the way.
2. Fully depress the clutch and only after a few seconds engage reverse gear.
3. Depress the clutch, set the gear to neutral and release the clutch. After this, press down and engage reverse gear.
4. Shift into reverse through another gear. For example, first engage 4th and then shift to reverse.

It's hard to engage first gear

Many drivers who encounter this situation try to force the gearbox selector to engage 1st speed. But this is fundamentally wrong and should not be done this way.

In this situation, it is necessary to use the regas method . Its essence is as follows:

1. While driving in second gear, depress the clutch and set it to neutral and then release the clutch.
2. After this, you need to press the gas pedal, increasing the speed to 2.5 thousand.
3. The next step is to engage the clutch again by pressing the pedal all the way and turn on the first gear on the gearbox. If you still have difficulties with this, then you need to repeat it, because... You gave too little gas, there were too few revolutions.
4. If all the steps are performed correctly, the first speed will turn on without any difficulties or sounds.

However, this method should not be used on an ongoing basis when it is difficult to engage 1st gear. This method is temporary in order to at least get to the service station without any problems. In any case, the box will have to be repaired.

Gazelle gear shift. The correct scheme: learning to change gears on a manual transmission

GAZ 3110 from 11.2002, manufactured, standing in a yard in Moscow, bought in the summer - the new owner has no experience with GAZ, drove a little after the purchase - in the surrounding area, last time - 3-4 weeks ago, 1st gear was difficult to engage from the moment of purchase - everything else is quite normal.
After moving it to a more convenient parking spot, 3-2 weeks ago, the car does not drive - there is no need, the tires are summer and the main thing is that the speed has stopped turning on.

The car warms up from time to time, the battery is recharged, BUT it is simply impossible to turn it on with the engine running from neutral, neither 1st nor reverse (or any other).

When the engine is not running, any gear is easy - it doesn’t matter whether the clutch is disengaged or not.. disengage the clutch, start it, move it forward.. or back until it’s time to shift..

What could it be - problems only with the switching mechanism, or with the box itself - help the kettle!

Re: the gears don't turn on - at all! There seems to be a normal amount of brake fluid in the clutch pedal, the clutch pedal is the same when pressed - with the engine running or not running, the free play is clearly greater than that indicated in the book..

I forgot to write, maybe the most important thing is that the gear shift lever rotates freely and can move up and down about five centimeters - maybe that’s the whole point?

Help me out, I got caught again with my VAZ 21103. A week ago, all gears stopped turning on when the engine was running, but when it was turned off everything was fine. Afterwards, I had difficulty getting to the service station: with the engine off, I put it in 1st gear, depressed the clutch and let’s start it – it started, only while the starter was running, the car began to move jerkily while the clutch pedal was depressed. The service was already closing, I left the car on the street until the morning.

When I come in the morning, everything is fine as if nothing had happened - everything switches back to normal. But I decided that I still needed to open it and see what was there. At the same time, I drove into the service center on my own with excellent gear shifting. In general, we took off the box and changed the clutch fork and release fork, because the old release fork had ground 0.5-1 mm into the mounting points on both sides. The basket and disc are fine - they ran half of them until they started replacing them.

Principle of operation

The working diagram of the gearbox is as follows. The drive shaft receives rotation from the driven clutch disc and transmits it to the intermediate one. If the gearbox is set to neutral speed, there is no engagement of the intermediate shaft gears with the driven one, the car is immobilized, since rotation is not transmitted.

When a gear is engaged, the driver engages the driven element gear with a specific intermediate gear. And rotation begins to be transmitted from the driven shaft to the wheels. The car starts to move.

The necessary gears are engaged by a control unit consisting of three sliders and forks. Each of the forks is equipped with a special groove of the element. That is, the driver, using the gearshift lever and a special rocker, acts on a certain slider, moving it to one side. In this case, the fork on the slide pushes the gear, and it engages. The change in gear shift speed is influenced by engaging gears of different sizes and numbers of teeth.

To prevent the slider with the fork from returning to its original position, the box control unit is equipped with latches. The latter are spring-loaded balls that fit into grooves on the sliders. That is, the slide has grooves in certain places.

This is a simplified description of the design and operating principle of a manual transmission.

In some cars, the slider in the gearbox, which is responsible for engaging the first gear, also ensures that the reverse gear is engaged. It happens to them that the first and reverse gears are difficult to engage. Of course, this breakdown cannot be ignored.

On other gearboxes, first and reverse speeds are separated and different sliders are responsible for turning them on. In such cars, problems with engaging first gear may not be reflected in engaging reverse gear.

There are several options why first gear does not engage well. It also all depends on how the cause manifests itself - it is impossible to turn it on, and everything is accompanied by a metallic grinding sound from the side of the box, or the speed turns on, but immediately turns off on its own.

Problems with automatic shifting

An automatic transmission is very demanding in maintaining the oil level and its condition, unlike a manual transmission. Too high or low oil level can lead to machine malfunction. In addition, due to a lack or excess of oil, difficulties may arise in switching gears.

The most common automatic transmission faults:

1. Forward gears do not engage.
2. There is no reverse gear, forward there is only 1st and 2nd.
3. All speeds are engaged except reverse.
4. The gears don't engage at all.

The oil level in the automatic transmission is checked using a dipstick. If the oil level is low, add.

What are the faults of the Gazelle gearbox?

Gazelle gearboxes are rightfully considered one of the most reliable and durable, but even they can become unusable due to high loads. In order for the replacement of the Gazelle gearbox to go without a hitch, you must know the hardware of the car, study the diagrams, be careful and patient, and also follow the safety rules and understand the principle of operation of the Gazelle 4x4 gearbox.

Checkpoint diagram

Gazelle repair may be required in some cases:

difficulty changing gears. This snag occurs due to the lack of fluid in the cylinder or due to the presence of air in the hydraulic drive. In addition, you can check the locking bolts, which often need additional tightening, as well as the transmission intermediate shaft. You can observe how the device jerks in neutral, and the transmission howls. Another sign is that in 4th gear, fifth or second, the device makes a howl, a lot of noise;

The gearbox engages with noise and crackling noise when starting. In this case, the synchronizer blocking ring on the transfer case could be worn out or deformed. Also check the power take-off. It is advisable to replace the blocking ring or power take-off box, and to ensure that the new element fits in without problems, use lapping paste. In addition, check the condition of the input shaft, how the mortar works, whether the car is noisy in neutral;

random shutdown of manual transmission

If you notice such a problem, first of all check the fastening nuts to the clutch housing, as well as the condition of the gazelle gearbox linkage. In addition, the couplings could wear out (worn out teeth), as well as the locking springs (they can either wear out or weaken)

You may also need to adjust the intermediate shaft and input shaft;

the appearance of extraneous noise. In order to get rid of them, it is necessary to replace bearings or damaged gears, add oil to the crankcase or check its alignment with the crankshaft.

Theory of gearbox operation

At the moment, all modern gearboxes are equipped with synchronizers, which are important elements of the gearbox. The essence of how synchronizers work is that they equalize the operation of the gearbox shafts.

Every driver, when switching from second to first gear, has encountered a situation where some kind of obstacle was felt. What prevents you from engaging first gear while driving. This is the synchronizer.

If you have a fairly new transmission, then when switching from an upshift to a downshift you will not find yourself in such a situation. Switching will be carried out without problems. This manifests itself as the components of the unit are used and worn out.

If you have problems with switching, come to Ankara for diagnostics and repair of transmissions of Mitsubishi, Toyota, Lexus, Land Rover, Jaguar, Infiniti, Mercedes, BMW, Audi and other brands.

Watch a video about the design and operating principle of the gearbox:

Owners of cars with a manual transmission often encounter the problem of poor gear engagement, which occurs after starting and warming up the engine, that is, “on hot”. In this case, engaging one or more gears may not only be difficult, but also be accompanied by extraneous noise or unnecessary vibrations.

In this case, the gearbox shifts normally when the engine is turned off. Next, we will look at the common reasons why this malfunction occurs, as well as what to do if the gears are difficult to engage when heating.

Seven troubles...

It is unlikely that it will be possible to describe all the problems of the box, or at least most of them; the owners who are offended by this capricious unit name too many of them.

First, I will try to at least list the most frequently mentioned ones:

• Difficulty engaging first gear for starting;
• Difficulty changing gears while driving;
• spontaneous transmission shutdown;
• crackling sound when switching;
• extraneous noises like when driving,
• ... and in neutral gear;
• oil leakage through seals.

This list is far from complete, but I will not delve into the very “exotic” nuances now, because there is clearly not enough time and space for this here.

In fact, these and many other malfunctions can be conditionally grouped as follows:

• caused by wear and/or destruction of bearings;
• caused by wear and/or breakage of the teeth of the constant mesh gears and fifth gear;
• associated with wear or breakdown of other parts (most often synchronizers).

And in addition to this, I would like to note that the reasons for the incorrect operation of the gearbox and/or its failure can, in turn, be distinguished as:

• caused by design defects and quality of components;
• caused by violation of maintenance regulations or vehicle operating conditions.

The latter, of course, applies not only to the NEXT family, GAZelles in general, but also to any cars.

Indeed, it is hardly a secret to anyone that heavy overloading, especially of light-duty commercial trucks, is a very favorite way to earn more money; Not many people think about what these “extra” funds will have to be spent on in the distant, or even not too distant, future.

The same can be said about “savings” on service and operating materials.

However, I will not advocate for strict adherence to the long-established rules of technical and commercial operation - all the boys here have long been adults, they must understand what’s what and how much.

Let's return to our sheep to the constructive reasons for the mentioned problems.

When modernizing the gearbox, the problem of the reliability of the intermediate shaft bearings was quite successfully resolved by replacing the previously used ball bearings with roller bearings, which, with proper operation, can last up to 200 thousand kilometers.

Gears are difficult to engage when hot: the main causes of manual transmission malfunctions

The manual transmission is designed to transmit torque from the internal combustion engine to the drive wheels of the car, as well as stepwise change the gear ratio. In a manual transmission, gears (steps) are changed manually by the driver, who also selects the optimal gear ratio, ensuring the best operating mode of the internal combustion engine while the vehicle is moving.

In the case when problems switching speeds occur when the internal combustion engine is warm, the main symptoms can be identified:

• Reverse gear is difficult to engage;
• shifting gears from high speed to low speed and vice versa is accompanied by extraneous noise, grinding or crackling;
• complete lack of ability to change gears;

The main causes of manual transmission malfunctions:

• low oil level in the box;
• the link is poorly adjusted or damaged;
• problems with the clutch mechanism;
• destruction or deformation of gears;
• wear of shaft bearings;
• failure of synchronizers.

So, often when heated, gears are difficult to engage due to low oil level in the manual transmission. Taking into account the decrease in the level of lubricating fluid, the coefficient of friction between the rubbing parts increases, which leads to difficult and unclear gear shifting.

• Often the reverse gear is not engaged “in hot” mode due to a malfunction of the linkage. This is a common cause of problems with reverse gear engagement, which occurs when the rocker mechanism is incorrectly adjusted or worn. In fact, a tolerance shift occurs when the gear shift mechanism moves (as a result of wear of the rocker joints or adjustment failure).

Table of malfunctions of the Gazelle box according to the nature of the noise

Now you know how to remove and rebuild the Gazelle gearbox yourself.

What's the result?

As you can see, there are several main reasons why gears don’t engage well when hot. However, none of the above reasons can be indirect or secondary.

The main thing is to promptly correct the slightest problems, prevent leaks, monitor the oil level in the box, adjust the rocker, change the clutch when signs of wear appear, etc.

Gears won't shift after replacing clutch

On the Gazelle 402 the gears have become difficult to engage.
I decided to replace the clutch. I installed a new basket, a Kraft disc, and a new cast iron release. After the replacement, the gears stopped turning on altogether. When the engine is off, they turn on; when the engine is on, they don’t. On the advice of friends, I placed washers between the basket and the flywheel to move the basket - it didn’t help. We pulled out the ball on which the fork rests - it didn’t help. I replaced the main cylinder and the working one - it didn't help. If you put it in gear and start the car, it drives with the clutch depressed. If you press the release bearing with a pry bar while the car is running, the gears are changed with your little finger. They say this happens when the disc is placed incorrectly, but it seems that they were placed as it should be - with the convex part in the basket, and even then the gears would not engage if you pressed with the pry bar. Everything has changed. Pumped up. But it doesn't work. There are no more thoughts.

Re: Strange value - 2cm > As far as I remember, the travel of the fork end with a working clutch drive is 14 mm. In my Volga with 402 this is exactly the amount. The bearing, as far as I understand, should move even less. > If the imported basket has a lower height than the original “claw” one, then place a thick washer under the support of the “soldier” fork. The problem cannot always be overcome by simply lengthening the rod - the fork will rest against the “bell”. > I heard about a washer with a thickness of 4 mm. I really haven't seen it.

"Soldier" was raised to maximum. This is two centimeters by eye, and this is the stroke of the release bearing. Now everything is set up in such a way that the release lever is already pressed against the paws, after pressing the clutch it still pushes them, but there is still room for maneuver. Now, if you press even further, then everything works.

Re: read carefully > “if the fork moves. and a fork. » > After replacing the clutch on a Luk, I also had a similar problem. I installed it myself, so there was no question about the disk. There were two options: either “move” the basket away from the flywheel with washers, or lengthen the RCS rod. I chose the first one - 100 tkm is no problem - but theoretically the second option is more correct, especially since an adjustable length rod costs 23 rubles, or is made from an old pusher rod. > I repeat that all this makes sense if the fork travel is insufficient. You can check this as it is written in the Kama Sutra.

I have already moved the basket away from the flywheel, the washers are about 2 mm. Did not help. He pulled out the rod on which the fork rests. Did not help. The RCS was installed so that the rod could barely fit onto the fork. Still doesn't work. All that remains is to look at the disk, either side. But if you help with a pry bar, everything is OK.

Reverse gear does not engage: common breakdowns

So, if engaging reverse gear is difficult or completely impossible, this breakdown is a common problem that can be encountered in different vehicles when changing gears.

Moreover, the rear does not engage both on manual and automatic transmissions (the reverse speed of the automatic transmission has disappeared). Naturally, in such a situation, it is important to discover the cause of the malfunction and eliminate the breakdown, since it is simply impossible to operate the car normally without reverse gear (the vehicle is actually deprived of reverse gear). Let's figure it out.

• Let's start with a manual transmission and consider the question of why reverse gear does not engage in a manual transmission. First of all, with a manual transmission the reverse gear fails much more often than with an automatic transmission. As a rule, the first signs of problems are a grinding, crackling or crunching sound in the reverse gear when engaged, the reverse gear is difficult to engage, it is difficult to engage the speed after a while, etc.

Please note that ignoring these symptoms leads to the fact that the reverse gear completely stops engaging after a while. Moreover, prolonged use of a car with such a malfunction can cause more serious problems and the need for expensive repairs of the gearbox and other components of the car.

As for the main malfunctions, we can highlight the following:

• The clutch does not disengage completely. As you know, the clutch connects the engine and the gearbox, and at the moment of changing gears the driver must depress the clutch pedal and “disconnect” the internal combustion engine from the gearbox. After engaging the gear, the pedal is released, the clutch “closes” and the torque is again transmitted to the wheels.

So, if the clutch is not completely disengaged, the gearbox is not completely disconnected from the engine. This leads to the fact that all gears are difficult to engage. At the same time, on many cars, first speed and reverse do not have synchronizers. As a result, clutch problems are most noticeable when engaging reverse gear.

In such a situation, when trying to engage a gear, a crunching and grinding noise is heard in the box. To eliminate the breakdown, you need to pay special attention to the clutch (condition of the clutch disc, basket, release bearing, etc.). You also need to check the clutch adjustments, the quality of the pedal, etc.

In other words, you first need to exclude breakdowns associated with the operation of the clutch control mechanisms (for example, the clutch pedal is soft, does not fully depress, or falls through). If everything is in order with the pedal and the mechanisms associated with it, you need to remove the clutch itself, troubleshoot individual elements, or immediately change the clutch assembly.

• The oil level in the gearbox is low or the gear oil has lost its properties. As practice shows, there is a common misconception among drivers that the manual transmission is filled with oil for the entire service life of the car. In fact, a maximum of 100 thousand km. Even the highest quality gear oil becomes unusable. And this is subject to fairly gentle operation.

If the car is used in difficult conditions (driving around the city, irregular pace, constantly switching speeds “up” and “down”, short trips, temperature changes, etc.), then the oil in the box requires replacement every 50-60 thousand. km. The fact is that the properties of the liquid change, additives are activated, dirt, products of mechanical wear of the box and various deposits accumulate in the oil.

Often, with old and dirty oil, the transmission begins to perform worse in all gears, but do not rule out the most noticeable problems only when engaging reverse gear. It is also necessary to periodically check the oil level in the gearbox, since its decrease causes increased wear of all gearbox parts, contamination of the lubricant with wear products and difficulty engaging gears.

• The gearbox linkage needs to be adjusted; the rods or gearbox drive levers are deformed. Often, it is after diagnosing the condition of the rocker that it becomes clear why reverse gear on a Lada and various foreign-made cars (especially old ones or with high mileage) does not engage. Owners of front-wheel drive VAZ models are well aware that a poorly adjusted rocker is the reason why the reverse gear does not engage or is knocked out.

The solution in such a situation is to adjust the manual transmission gate, which can significantly improve the clarity of the inclusions and obtain the necessary softness. Also, in some cases, owners remove the standard mechanism and install a short-throw slide, but in this case you need to be prepared for the need for more careful adjustment. As for the gearbox rods and drives, these elements must be inspected for possible damage or breakage, after which they are replaced.

• Design features of the gearbox. Often on budget cars, reverse and first gears do not have synchronizers. The absence of these elements, on the one hand, simplifies the design of the box, but on the other hand, difficulties arise when engaging reverse gear and first speed.

So, such operation of the gearbox cannot be considered a breakdown. Rather, it is a feature. To achieve a smooth engagement, you need to practice double-depressing the clutch before engaging reverse gear. Experienced drivers also advise engaging first before engaging reverse gear.

Reverse speed of automatic transmission does not engage

In practice, reverse gear may not be engaged in both manual and automatic transmissions. Taking into account the fact that automatic transmissions are different, it should be noted that some problems of manual transmission robots are similar to “mechanics”, while “classic” automatic transmissions have their own list of problems due to which the reverse speed disappears.

• The level of the ATF transmission fluid has deviated from the norm, the fluid in the automatic transmission is contaminated or has lost its properties. As you know, an automatic transmission is extremely sensitive to the level and quality of oil. For this reason, the check should begin with the transmission fluid.

Please note that both under and over levels can cause gears to shift incorrectly. Also, ATF oil has a limited service life, that is, the fluid needs to be changed every 40-60 thousand km, contamination, cloudiness, etc. are not allowed.

• Wear of automatic transmission clutches (friction discs). This malfunction often affects both reverse gear R and gears in drive mode D. Problems with clutches lead to gears not being engaged, and certain speeds may disappear (for example, the car goes to 1 and 2, but not 3 and 4, as well as reverse gear). To fix the problem, you will need to replace the automatic transmission clutches.

• Other automatic transmission malfunctions and breakdowns. For example, if the splines of the drive drum are cut off, the machine can move forward, but there is no reverse gear. There may also be complete absence of movement both forward and backward. To solve the problem, the drum needs to be replaced.

Another reason may be a brake band and a worn friction layer. Problems may also affect the clutch pack of the reverse gear R. In this case, the box works normally in drive mode, but when reverse is engaged, there is no reverse movement.

We also recommend reading the article about why manual transmission gears are difficult to engage. In this article, you will learn about the main reasons why shifting gears can be difficult on a manual transmission.

Other problems include broken brake band piston cuffs or severe wear. The malfunction only appears when the driver engages reverse gear, that is, the car moves forward normally, but there is no reverse movement. Another common problem with similar symptoms is failure or jamming of valve body valves and individual solenoids.

Additionally, experts draw attention to the fact that if there is no connection between the oil pump drive gear and the torque converter, the automatic transmission will not engage in both forward and reverse gears.
