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.
Replacing a car's rocker, eliminating play
The design of the gear lever movement device is invented with the aim of uninterrupted operation of the gearbox. You can repair the backstage yourself or with the help of a partner for convenience. Most car enthusiasts are inclined to replace the standard rocker with a short-throw one. Installing a short-throw rocker is a type of tuning that allows you to reduce the limit of movement of the gear shift lever.
When using such a link, gear shifting occurs clearly and quickly. The process of replacing a regular link with a short-stroke one is quite simple. It is necessary to lift the fastening of the iron rod that runs from the gearbox to the shift lever in the passenger compartment. In this case, it is not necessary to remove the link; you only need to disassemble the spherical support.
Then open the iron ring until the plastic tabs move apart and the ball is released. After this, loosen the clamp near the gearbox, disconnect the rod and drag it in using the dirt cover. While in the pit, cut off the parts and weld a pipe into a rod, no more than 2-3 mm thick, and a piece of sheet metal, 5-6 mm thick. The rod is usually cut off by 2-4 cm.
A simpler option, but quite expensive, is purchasing a new rod. A short-stroke slide costs about 700 rubles.
Large play on the rocker is a disease of the car model in question, the cause is the original gearbox driveshaft. To carry out repairs, you need to purchase the cardan itself. For this car, it is suitable from Kalina; it is purchased together with the boot. For the repair itself, a minimum of tools is required: keys “13” and “10”, a screwdriver and a hammer.

Repair or replacement is carried out on an inspection pit or lift. You will need the assistance of an assistant to make subsequent adjustments to the shift lever. Using two keys set to “13”, stretch the clamp on the rod and pull the drive off the rocker rod. Use a screwdriver to push the boot towards the gearbox or remove it completely.
Unscrew the bolt and knock down the cardan with weak blows of a hammer. Installation of a new one is carried out in the reverse order, that is, first you need to put the boot on and the cardan on the shaft. After the bolt aligns exactly with the recess on the shaft, put the boot on the universal joint.
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.

Engine mounts
I personally have never had this happen, but many people write that this is a fairly common problem. Actually, the problem is this: the engine hangs on cushions, the gearbox is connected to it (manual transmissions, by the way, have their own cushions). It happens that the fastening breaks, or it unscrews. The engine or “box” may sag, the scenes may break, or they will hit something.
THEN there is another not very serious problem - these are pillows! If the programs don’t turn on, then we watch them.
These malfunctions, AS I THINK, ARE NOT PROBLEMS AT ALL! Anyone can identify them on pits or lifts, and this is done quite quickly. Personally, I came across rockers and cables, using the example of a VAZ, a clutch cable.
However, if you have checked everything, and the gears do not engage with the engine running. Then it’s worth looking at the box itself and the accompanying attachments. Let's move on to complex faults.

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
Repair
If the described adjustment did not help you, you need to remove and disassemble the VAZ 2110 gearbox. Pay special attention to the fact that the gears with which the first and second speeds are engaged often knock out. Be sure to check each fastener.
Another complaint is that the second gear is difficult to engage and is often knocked out.
Here you can suspect the main culprits:
- the second one flies out most often because the gear teeth do not mesh well with the clutch that turns on the speeds;
- The tips of the gear teeth and clutch are already worn out, so the speed is difficult to engage. If you don’t intervene, it will soon fly out;
- as an option, when it knocks out on bumps, the clutch dies.
Sometimes (albeit rarely) when the second one does not turn on well enough and falls out, replacing the retaining spring helps. If the speeds often drop out, some of them are difficult to turn on, which means that half-measures will no longer help - the box needs to be overhauled.
Whether you do it yourself, or go to a service center where they will repair it for you and also adjust the gear shift mechanism, decide for yourself, based on your own experience and skills.

VAZ 2110 16 valve gears don't engage well - reasons
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
