A manual transmission has its advantages over an automatic transmission, and many drivers still prefer it when buying a car. One of the advantages of mechanics is its unpretentiousness, as well as the low cost of repairs in case of damage to the elements of the box, compared to an automatic variation.
A common symptom indicating that there is some problem with the transmission is that it makes a crunching noise when changing gears. If you hear a crackling or crunching sound when moving the gearshift lever and engaging gears, you need to contact a service center as soon as possible.
Important: You should contact a service center not only because of the likelihood of causing more serious damage to the gearbox and other mechanisms, but also because of the risk of an accident if the gearbox fails.
How does a crunching sound manifest in a gearbox?
There is an unspoken rule among drivers - to start driving a car with the radio turned off. This is necessary to immediately check whether there are any extraneous knocks, noises or other sounds that may indicate a malfunction of a particular unit. The following sounds will indicate problems with the gearbox:
- A crunching sound when engaging a gear, and often it can only appear in one of the gears, for example, in reverse;
- Crackling noise when returning the gearshift lever to neutral.
If you notice one or both of the symptoms in the operation of your box, you should determine and eliminate the cause as soon as possible.

Why does the gearbox crunch?
There are many reasons why a crunching noise occurs when the gearbox operates. Eliminating some of them does not require much intervention in the mechanism, while others require a near-overhaul of the box. Most often, the gearbox crunches when changing gears for the following reasons:
Synchronizer malfunction. The problem may lie either in the failure of the element or in the insufficient amount of lubricant in the part. If the synchronizer has “crumbled” due to age, the lubricating components with the resulting “garbage” risk causing serious damage to the entire unit, so the situation needs to be corrected as soon as possible;
What to do
To avoid expensive repairs, it is necessary to correctly diagnose the breakdown. If the problem is still in the gearbox, it should be addressed urgently.
Provided that your car has a manual transmission, you can carry out repairs yourself, based on the car’s operating instructions.
If you have a “robot” or “automatic”, it is better to leave diagnostics and repairs to the car service specialists. Improper intervention threatens to replace the entire gearbox, and the price for such gearboxes is much higher than for manual transmissions.
How to avoid crunching noises in the gearbox
Most often, gearbox malfunction occurs due to improper care of it. Manual transmissions require regular lubrication, which drivers often forget about, assuming that such procedures are only required for automatic transmissions. If the lubricant loses its properties, this can lead to serious consequences, including failure of individual components and mechanisms.
Experts recommend replacing the lubricant in a manual transmission every 45-50 thousand kilometers. If the vehicle is driven under particularly severe conditions, change the oil more often.
Please note: It is especially important to promptly change the lubricant on a front-wheel drive vehicle.
By lubricating gearbox and suspension elements in a timely manner, you can avoid expensive repairs and early failure.
Hello everyone. The second gear shifts with a crunch. I know it's synchronous. Tell me, how much does a synchronous replacement cost and how long can you drive?

Correct it yourself: AVTOVAZ instructions for eliminating the crunching noise when engaging the 2nd gear of a VAZ gearbox
When operating Lada cars on which a gearbox marked VAZ-2180, 2181 or 2182 is installed, a malfunction of this type may often occur, such as a crunching sound when engaging second gear.
At the AvtoVAZ plant, a special methodology was developed to prevent such a development of events and make it possible to assess the presence of non-compliance. In addition, the factory instructions indicate how to avoid trouble. The methodology was provided by one of the brand’s dealers. Gearboxes of the indicated names are used on LADA cars: Vesta, XRAY, Largus, Granta, Kalina, Priora.
It is worth paying special attention to the following points:
- If the car was produced earlier than December 31, 2014, then check the markings of the 1st-2nd gear fork and if there is a marking for the fork 2181-1702022 (old condition), it must be replaced with a fork 2181-1702022-01 (new model);
- On cars manufactured before 07/01/2017, check the markings of the 2nd gear gear and if there is a marking for gear 1701127-00 (old condition), it must be replaced with gear 1701127-10 of the new model (21800170112710, 21810170112710), similarly check if available replace the input shaft 2110-1701030-00 (old condition) with the input shaft 2110-170130-10 (new model).
Eliminate crunching. The most common causes of crunching noise in the gearbox are:
- Wear of gearbox synchronizers. They, no matter how strange it may sound, are required to synchronize the rotation of the clutch and gear in the box. In simpler words, when the synchronizers wear out and the gear is engaged, the gear teeth begin to dig into the clutch. The result is severe wear, and if you apply more force and frequently engage the gear with a crunch, this will not lead to anything good, since the gear will begin to “fly out” and then one day will not engage at all.
In simpler words, when the synchronizers wear out and the gear is engaged, the gear teeth begin to dig into the clutch.
Failures that cause crunching when changing gears
Crunching noise when shifting gears can be caused by several factors. The first and, admittedly, most popular is considered to be the breakdown of any unit, and the crunch in this case is only a symptom. Among the main breakdowns that cause such unpleasant sounds when switching gears are: 1. Failure of synchronizers . Synchronizers are responsible for smooth gear shifting. Over time, they wear out and cause a crunching sound when changing gears. Fixing the problem is quite easy - you need to replace these same synchronizers. However, only professionals should be trusted to carry out this type of repair. 2. The falling out of the clutch basket can also cause a crunching sound when changing gears. Replacing the clutch basket will eliminate this defect. 3. Clutch malfunction . Well, here words are superfluous - go for diagnostics, they will establish an accurate diagnosis. 4. Problems related to the gearbox shaft . The problem can be solved by replacing this unit.

Incorrect operation of the transmission, as the cause of a crunching sound when shifting gears
It is fair to say that often a crunching sound when shifting gears may indicate that the manual transmission is not being used properly. Therefore, it would not be amiss to provide some recommendations that will extend the service life of the manual transmission.
1. Timely replacement of transmission fluid in the box . Few people know, but in a manual transmission, just like in an automatic transmission, the oil should be changed periodically. A manual transmission does not require replacement as often as an automatic transmission, but still, after 70,000 kilometers, you should stop by a service station. If you ignore this recommendation, metal shavings and dirt will begin to accumulate in the oil, resulting in insufficient lubrication and crunching.
2. An insufficient amount of oil in the transmission can also cause a crunching sound when shifting gears. The solution is to add oil or, better yet, replace it .
As you can see, it’s quite easy to avoid crunching noise when changing gears!
What causes grinding noise in automatic transmissions and automatic transmissions?
It is a rare occurrence when the automatic transmission on a Kalina begins to make extraneous noise. The reason may be untimely replacement of transmission oil when its viscosity decreases. The layer applied to the rubbing surfaces becomes smaller, and lubrication becomes worse. It is recommended to change the oil every 60-70 thousand km.
Noise in an automatic transmission can come from worn bearings and gears.
The Jatco company (it was from this manufacturer that automatic machines were installed on the Kalina) stated that the service life of the box before major overhaul is 250 thousand km.
If you are close to these numbers, then it is best to take the car to a technical inspection station, where they will conduct a full diagnosis of the gearbox.
In the case of an AMT (automated gearbox), an extraneous grinding and squeaking noise can be produced by the clutch actuator. Most Lada Kalina owners recommend removing and disassembling the unit. If the lubricant has dried out, it needs to be renewed: this is what causes squeaks. Be careful with the spring that is located in the actuator: it is charged with great force.
Clutch Actuator
Also inspect the actuator housing and the spare parts located inside it. They must be without visible mechanical damage.

Help, friends.. I don’t know what to watch anymore.. The question is more for the experts
This is not the first time I’ve been going through the box on my swallow, but this is the first time I’ve encountered something like this. (VAZ 2112)
Replaced with a new one: Second gear Block ring of the second clutch 1-2 gears assembly (i.e. + hub with retaining springs) 1-2 gear shift fork rod of the 1-2 gear fork (too annoying) plus, of course, the third gear and GP gear on the differential)
result: everything is as it was before the bulkhead. The second one sticks in and comes out immediately after releasing the clutch.. if you release it sooooo slowly, it won’t fly out, but if you half-add the gas, it goes straight to neutral..
People please tell me what to do. Today the second gear started to fly out... it engages, but as soon as you release the clutch, it immediately crashes out (((Mileage 30350... Before that I went to the dealer, about 1000 years ago I did the maintenance myself. Now I’m thinking what to do... and the warranty seems to be up to 30500 (provided they don’t notice the homemade maintenance =)))
what to do? please advise!
Video “How to solve the problem of poor gear shifting?”
The Avto-Blogger channel made a video that describes all the nuances of poor gearing in a car when the engine is running and gives recommendations for solving such a malfunction.
I've read a lot about this in the last hour and am confused about what needs to be done. And my situation is the following, I squeeze the clutch, the speed is tight... but it turns on (but very hard) with the second one in the same way, I also remember the words of the master at 15 thousand like turn it on through the second one), so now it’s not possible to turn it on through the second one, well, if it does to overcome this tight inclusion, then the subsequent times 1st and 2nd come in so that it breaks into a smile (very easily), there used to be moments when if you switched super sharply there was a crunch, for example from 1st to 2nd, but somehow I got used to it and everything went away, oil in korobos it is replaced by semi-synthetics.
