Well my friend has a auto n/a supra (86.5 I think) and when he drives it it shifts very soon whether it be WOT or barely any. Anyone have any suggestions? Thanks in advance and btw there isn't any trans codes.

Your going to have to try to give a little more info....maybe your ECT ECU? its a little small control box thats at the bottom of the passenger kick panel...it controls the tranny
