Hello dear forum community! Have some problems with my automatic. Maybe someone has already had this or has an idea. The symptoms of my gearbox are as follows: Only if the gearbox is warm, then it jerks when switching from the 2nd to the 3rd gear. And that is every time the converter bridge snaps. That is, when the gear is inserted and the speed drops, there is a jerk at the end. This happens also when switching from the 3rd to the 4th gear. I think it’s a lot worse, for example, when I start at a traffic light, when the gearbox turns down from the 3rd to the 2nd gear (foot from the gas), it’s sometimes jerking and it pops in the 2nd gear. This doesn’t always happen often. Only when the gearbox is warmed up (e.g. 10-15km of city traffic). It was already with Renault. They can only read out the fault memory. It was already in an automatic workshop. They could not detect a mechanical defect of the transmission. Unfortunately, the no diagnostic device from Renault (CLIP) to perform a deep diagnosis. The master claims that the motor electronics sends wrong values to the transmission computer and thus causes the hard packing when switching. We have already checked complete electronics, including Lambda probes. No errors found. Gear oil level is also o k. I have changed gear oil already (about 10L). I am already quite desperate. I have the problem since August 2008.
