Prior to replacing the automatic transmission fluid (to improve shift quality), make sure that the transmission fluid level is correct.

    After taking to repair shop the car returned with shifting problems. Now the car will rev into 3000-4000 before trying to shift. This is causing other problems and trouble codes.

    haven't fixed yet

    thought it was just due to being in excess of 80k (about when it started). Been dealing with it for over 85k miles now (over 165k on ODO)...
