If I can finded a used one that I'll try that. My Gear set is going to be good. Before I got the transmission rebuilt the rpms where good.I did have a bad map sensor and it did in fact prevent the torque converter from locking up. Once changed the TC did in fact lock up. I just got through rebuilding the valve body also, had a few sticky valves. Hope to test drive it Monday and let you know what has happened
Ok so after much reading and determining that it could be alot of things and some included pulling the transmission again which I did not want to do. So I got out a handfull of chicken bones shook them in one hand and threw them down onto the shop floor it looked as though I should read the codes and they said code 22 MAP sensor out of range, now this could not possibly be related to the OD not locking up I am convinced that the OD solenoid is the culpret. So off to town I go to locate a new MAP sensor ( has to be changed to clear the check engine light anyhow) and an OD lockup solenoid. So I could only find the MAP sensor local the OD solenoid was some where back east and even the local ford dealer had none and wanted twice the price anyhow. So I went home with my new MAP sensor to replace the one that checked bad ( found it's location by reading another thread) thanks. So now I changed out he sensor and back to the chicken bones, tossed them across the garage floor again and they looked favorable so now for a test drive, well now it shifts through all the gears and even locks up the torque converter. So was it the MAP sensor or the chicken bones? My library transmission book that I read after the fact says that the MAP sensor can cause the torque converter to not lock up, how are they related? Well thanks to all of you for the very helpful posts. Anyone not experiancing a torque converter not locking up should check that MAP sensor before they tear into the transmission.
