Does anyone know if it is possible to reset or erase the memory in the transmission of a V8 awd STS? My car, '05 STS4 V8, has gone back to horrible shifting that was finally cured by a TSB. That lasted about 8k miles. Now it is back to up shifting horribly, near impossible downshifts with hesitation and confusion, and general clunks and clanks at all speeds regarding gear change. Since it seems to relearn this improper behavior I was thinking a relearn might prevent another argument with the dealer. I tried disconnecting it for the night but the memory of everything remained including radio, etc.
