Why the reverse gear of the VAZ 2109 disappeared and does not engage: reasons and repairs, video on how to adjust the gearbox and turn on the speed


The car is 1989. 1.5carb. There was an ordinary box with a dipstick, but it became unusable. She started making noise, and then refused to go at all. Since the new ones are expensive, I took a used one, took it from people who drive cars around the hill and then fuck them up. They had a lot of gearboxes, but they told me they would give me the one with only 30k mileage. Afterwards I saw that 5 I had already changed on it, but it was too late to return it.

At the same time I changed the clutch, except for the basket, it is still normal. I installed a Kalino cardan. I filled in mineral oil THK Trans KP 80W-85, tried to fill in a little more than the norm, as everyone advises on the net, somewhere around 3.400

Problems: when the car warms up, some kind of incomprehensible sound, when the clutch is depressed, disappears, does not hum, but as if a cat is squeaking :). I warm it up for 3-5 minutes, at an outside temperature of 0, and then I drive, and it can squeak for some time, by the way, the sound is similar to the sound of a reverse gear when driving. In 4th and 5th gears, when coasting, as well as in tension, you can hear a small crunch, a crackling sound, not uniform (after complete warming up, it disappears). The 5th gear is humming, although I disassembled the body of the 5th gear and looked, everything seems to be ideal there. When the box is completely warmed up, it only buzzes in 5th and that’s it. Then there is discomfort when changing gears. They seem to cling a little and do not crunch, but simply make very unpleasant sounds, they even knock, and this is when switching. You can hear how the blacks go through the gears in it and everything goes to the gearshift knob
