Car : VAZ-2110. Asks : Nut. The essence of the question : the speed does not turn on when the engine is running?
Hello. If you start the engine in neutral and then try to change gears, nothing will work. Car VAZ-2110 8 valves, in 2004 . It hits something and there is a terrible crunch. If you press the clutch and turn on the speed, and then start to start, the car goes forward, what is it?
It was very scary, they told me how to start in first gear. I just turned on first gear and the starter. The car started moving, I released the starter, and drove home. I left the car in the yard.
Before this, a strange rustling sound was noticed when pressing the clutch pedal.
Why doesn't either first or reverse gear engage when the car is started?

Gears engage with effort: gearbox malfunctions
In cars with a manual transmission, gear shifting is done by the driver himself. Using a lever from the interior, it acts on the rocker and then on the entire gearbox mechanism. Simply put, the driver moves the gears on the shafts.
Since the shafts rotate at high speeds, cooling is required. This is done using special gear oil. Oil also protects the surfaces of rubbing parts from premature wear. The lubricant must be changed on time. On average, this is done after every 40-50 thousand kilometers.
As for the reasons for tight gear engagement, there may be several of them. However, most often they are associated with problems in the clutch or the gearbox itself. If you study the list of the most common breakdowns, then you can highlight the following:
The exception is reverse gear, since it does not have synchronizers; By the way, when the reverse gear is difficult to engage, extraneous noises, clanging, and crunching often occur. Such phenomena directly indicate wear of the gear teeth.
Transmission device
So, the gearbox diagram is quite simple.
There is a housing attached to the clutch housing. This housing contains three shafts - drive, driven and intermediate. The peculiarity of the arrangement of the shafts is such that the drive and driven shafts are on the same axis, and at one end the driven shaft enters the drive. An intermediate shaft is installed below them.
On each of the shafts there are gears of different diameters and with a different number of teeth, while some of these gears mounted on the driven shaft can move along it.
What's the result?
So, the main reasons why gears are difficult to engage are problems with the clutch mechanism and gearbox. However, most of them can be eliminated yourself if you have tools, spare parts and certain skills.

Recommendations from experienced car owners and mechanics
You can often find owners of cars with an automatic transmission that delays switching between speeds. But this is not yet a reason to panic and save large sums of money for repairs. Some problems with tightening can be eliminated in ways that are accessible to everyone.
“A couple of years ago I bought myself a purebred American Mercury 1996. Even during testing, I noticed that the box delayed the shift between the first and second. The former owner said that delaying when choosing a gear is the norm for such a car. After consulting with mechanics, I became convinced that this was not such a terrible disease. I didn’t bother going through the box; I’ve been driving it like this for 2 years. I try to accelerate smoothly, and then this hitch is almost unnoticeable.”
“I have been working at an automatic transmission service station for 8 years. We sort through the boxes of “European” and “Japanese”. Many customers come to us with complaints that the automatic transmission takes too long to shift. We do computer diagnostics for 2 thousand, if it requires repairs, then on average it costs around 15 thousand rubles. Most often, the solenoids on the hydraulic plate need to be replaced; they poison the pressure and delay the change of stages. In terms of time, it takes one day, if there are no queues.”
“I’ve been driving my “swallow” Passat for 8 years now, and recently I started noticing that the automatic transmission is dragging its feet with gears between second and third. This became annoying and forced me to go to a service station with friends. The guys there recommended completely changing the oil using a machine. I didn’t argue; I’ve been servicing my car with them for a long time and trust them. Within a couple of hours, everything was done: oil, filter changed, pan washed, magnet cleaned. After this procedure, the car began to drive like new! I paid 7 thousand for everything, considering that Phoebe took the oil, and it took 12 liters.”
“I got my license while still in college, but I bought the car at a conscious age. I drive carefully and undergo maintenance as required. But a month ago I began to notice that the automatic transmission was slowing down and dragging, and was moving to the third stage late. In a panic, I called the mechanic, telling the situation. He reassures and asks to check the oil level. And for sure – it doesn’t reach the level. On his advice, I bought transmission fluid, added it and a miracle happened - the gearbox works like a clock again and doesn’t delay acceleration! That’s how I fixed the problem myself in half an hour!”

Topic: Gears don't engage well (they hit something and grind)
Hi all! I didn’t find anything similar on the forums. The situation is like this, VAZ 2110, 16kl, 04. At first, 1st gear was difficult to engage from time to time (it rested on something), then 1st and 2nd were engaged with difficulty and every other time, reverse turns on with a slight grinding noise, sometimes not the first time. Then 1.2 hardly turn on, they rest against something, then I noticed that if the gearshift knob is not pushed to the left all the way when shifting gears to 1.2, then the gears are engaged (no grinding, but like on a washboard), it turns out that 1 and 3 are very close, as are 2 and 4. The clutch pedal is slightly lowered. I pulled the cable, the pedal became slightly higher than the brake pedal, then the gears began to engage as expected in the extreme left position (again, as on the washboard), 3rd gear seems to click there. The travel of the clutch pedal has increased (very inconvenient) and the clutch engages with the engine only at the very end. YES, AND THIS IS ALL BOTH INITIALLY AND AFTER TENSIONING THE CABLE BOTH WITH THE ENGINE RUNNING AND ON STUFFED. Can anyone tell me what? They say on the forums that since they don’t shift gears when the engine is switched off, it’s definitely a case of removing and repairing the gearbox. Could there be another reason? I don’t want the service department to take the trouble to repair the gearbox for nothing. Thank you all

Re: Gears don't engage well (they hit something and grind)
Well, first of all, pay attention to the clutch and in particular to the basket, and if it is already all crooked or askew, replace it. Try to adjust the rocker to the position where it will engage best and at the same time unscrew the bolts with the speed locks, there are 3 of them, well, this is more likely to calm the soul. If not, then most likely the gears have come to a halt and this is just a repair. Only if you take it to the service station, be as close as possible when they start disassembling it, otherwise they will issue you a bill for a new box; it will be easier to buy, and they can take out the good parts
Knocking out the speed
Communities DRIVE2 Audi Club Blog Which S tronic is installed on which models
If it turns on, but immediately turns off, then the latch may be stuck in the squeezed position, so it no longer does its job. It is also possible that the spring that presses the ball retainer is destroyed. Without the force of the spring, it will not be able to hold the slider in the desired position.
If significant force is applied while shifting into gear, the shift fork may bend.
If this happens, then the gears will no longer fully engage, and the slider itself will not reach the stop, which will prevent the latch from entering the groove.
Poor switching may also be caused by incorrect installation of the gearshift knob. In this case, the rocker does not bring the gear to full engagement.

I have the same *****, I haven’t solved the problem yet, let me know if anything is resolved
As soon as I solve the problem I will post it.
Check the clutch pedal travel and make sure there is nothing obstructing it. Happens.
No, everything is fine, I checked it right away, right down to the floor. It seems like there might be something wrong with the box, damn it.
I have exactly the same problem. It hits something. If you repress the clutch, it sometimes helps. It happens with reverse speed too. I've been driving this way for almost a year now, and I'm already used to it. In the workshop they said the disease is ten-thousand and you can live..
I’m not going to leave this matter like this, otherwise sometimes when it doesn’t stick in all the way, out of habit I still start to move away and in the box the gears are clearly not fully engaged and there’s a crunching sound, and I’m afraid this may lead to the box being repaired
