I didn't know for a long time, but now I have to do some research.
My 89er automatic has sporadic and incomprehensible problems when switching.
==References====External links== Switch and the kickdown doesn't feel like doing anything. Whenever this problem occurs, it also reacts very abruptly and jerky to gas-give and take away gas.
Pull over briefly, engine off and on again, and the error is eliminated. Then it switches through all the gears again cleanly, the kickdown functions and also when giving / letting go it rolls smoothly.
Ah yes, and twice in the last three weeks, the gearbox ran in the emergency program, engine out and back and everything is fine again.
It can't be much, just what?
I am grateful for ideas
