I am not really sure if its a tranmission problem or what it is.
Im new to this forum, and hoping I could get some advice on what to do or where to start looking. Here is my problem I am having with my Audi 2002 A4 2.4 v6 B6. with 65000kms on the clock and I am experiencing the following. When the car is cold (first run of the day, or after a few hours of being parked), I do not have this issue as well as when the revs are below 1200 or above 1900. It feels like the car is unsure of when to change, and the revs blip up by 200rpm, but does change gears. This only happens at normal running temp and between 1200 and 1900 rpm. Also it feels like the car jumps/shudders during when it changes but this doesnt happen every time. I have put the car on diagnostics, and no codes whatsoever! I have
taken it to various mechanics around my country, and all are dumbfounded! Any suggestions would be greatly appeciated. We have changed the ATF oil etc.
Note that it DOES change gears, and when it is in that range of RPM it has this problem with any gear. When it is above 1900rpm it does NOT have this problem in any gear.
