I have a 92 ranger 3.0L with the a4ld transmission, The truck will not move if the shift lever is placed in Overdrive. If I place the shift lever in Drive it drives and shifts ok. Replaced the transmission with a used (original transmission the fluid did smell a bit burnt and was very dark) one do not know any history of the used unit (if did come out of a 89 ranger pickup, had to change the bell housing to mount on the 3.0L) and have the same problem. I have adjusted the bands (10ft lb and backout 2 turns) Checked the codes with 111 for the KOEO and CM. If I remove the 3-4 shift and TCC plug from the transmission I then get codes 566 and 629. I have run the output state test and I have 12 vdc when checked at the tranmsission plug between the RED and ORG/YEL (3-4 shift) and the RED and PPL/YEL (Converter Clutch). When not in the output state test mode the voltage reads 0 for both. I have made a jumper cable to control the solenoids manually. If I energize the 3-4 shift solenoid while the shift lever is in overdrive the truck will move and appears to shift ok. I can energize the TCC above 40 and that also appears to work.
My question is when should the 3-4 shift solenoid be engergized? Does it deenergize to shift to 4 or energize to shift.
