:angry: Yesterday We put a rebuilt tranny in my 88 taurus 3.0 and it is shifting into drive where it should be shifting into 2nd, It has to hit about 35 or 40 mph to shift at all, can anyone tell me what it might be or what i can try????? PLEASE
Apart from that it would seem that you have either a Valvebody issue and or governor issue.
Honestly you should probably get pull it back out and make sure that all the check balls are in the right place in the valvebody and you should probably also check the governor inside the transmission.
old chrysler 31TH transmissions use to have a problem where the valve in the governor would stick open and not allow the vehicle to shift.
