I want to introduce myself, my name is Sascha, I am 34 Jare and come from the beautiful Mainz on the Rhine

ICh has been driving an S6 C4 4.2 with automatic gear KB CST since last year.
For some time now, it's only been switching badly from the first to the second. It seems like it hangs, then the speed suddenly goes up, then the gear goes in. Since it is very similar to V8 technology, I hope I am in the right forum.
Thanks for your help!!!
Welcome
Sascha
Oh yes, oil level is ok ;-)
