Ok Guys! I've seached and searched for some answers about trying to "reset" my vehicle's computer (PCM) or possibly the transmission. I currently have a mild "bump" sound that happens between upshifts 1 & 2 and vice verse. I read on transmissions where some stated that they took it to the Dealership and they said it was caused by the PCM needing to be reset. Please if any of you have some insight on this please chime in.
