If my car still drives fine in reverse. Is my torque converter fine?

What is your question?

My Audi has no engine codes. Shifting sounds fine. When put in drive will start driving. But then the engine tries to redline for a sec while losing acceleration eventually slamming back in. Reverse has no probs.

What makes this problem better or worse?

Worse when warm

How long has your 2001 Audi A6 Quattro had this problem?
