So I used INPA and it gave me :

146 CAN Moment interface.

Every time that error shows up its at 6176 rpm. I have changed the transmission fluid and filter. I can't find anything on that code. Please help
Is the transmission related firmware/software up to date? Has it been modified in some way?

Has your car always exhibited these characteristics or is the problem new?

Have you posed this question to the AA guys? Could it be AA related?

Are we correct to presume that shifting occurs correctly at say 5k RPM or even 5.5K and that these problems occur specifically at 6k or 6.176k?

Are you somehow "controlling" the shifts by initially selecting D4 (or whatever it may be) then moving the leaver to D3 thereby "signalling" the shift to next ratio?
