I recently swapped in a used 2010 A6 transmission in place of my 07 A6 transmission for the firmer shifts, etc. I also carried over the 3200 Yank SS stall that was on my old trans.
We used tunercat to do the VIN match on the new TCM module and verified the write with HP Tuners.
The car will not shift out of first. It gets stuck at 40mph in 1st gear and HP Tuners Scanner shows the car is commanding 6th gear at that speed, however, the car just bucks and doesn't shift.
If I press the paddles, the "1 - 6" readout does not show.
Any ideas as to what could be wrong? Thanks for any help - this is very very frustrating.
