A6 Transmission Issues
I continue to have intermittent problems with the race-built A6 transmission in my trailered, drag race only C6 GS (see signature). The problems include hesitation on the 2-3 shift, staying in 3rd gear after the burnout, and on one occasion locking up after the burnout like it had a transbrake. I am considering using the manual paddle shift to make a few test passes to see if this overcomes the issues. I want to avoid pulling having the trans pulled and sent back to the builder. I have been operating under the assumption letting the trans do the shifting (assuming in works) is better than manual shift but t this point I am willing to try just about anything.
I will appreciate feedback.

The other thing is to do a trans adapt reset with a Tech 2. Last summer and totally out of the blue my transmission wouldn't make any WOT shift properly but after doing the adapt reset it was perfect again.

As I think I had suggested previously, I would try a new valve body and TCM as this fixed some odd behaviors for me that a fresh rebuild didn't. This can be done without pulling the transmission and if you're willing to put in the time, it can be done in your garage.

If you had a stock trans, I would be more than happy to share my tune with you. I seem to have lucked out with mine (knock on wood).
