91 2wd f150 with a 302 H.O. and e4od. just put the motor in drove about 2 weeks and i shut it off put it into gear and the transmission is not responding at all! im not sure if the wiring harness got hot enough to crystalize the wires or if its a solenoid. any insight where to start? i ran the codes and they were map sensor, vehicle speed sensor, nds, and trans not in park.

 

did you check to make sure the neutral safety switch is plugged in and all connections are good?

 

I'd start with checking the Park/ Neutral safety switch, the VSS and any related harness.

 

im gonna replace the harness! but would the nuetral safety switch allow it to start but not engauge the tranny? i can shift through all the gears but it seems like the trans is not responding at all

 

well i didnt have the spare harness but i did inspect it took the nss off and cleaned up everything and still nothin. so i am so lost! can anyone tell me what i will need for a c6 conversion
