I have a 01 expedition that i recently installed a 4r70w out of an 04 expedition after replacing internal gear where spped sensor reads installed and have no 1st gear or over drive takes off in 2nd gear and never even tries for over drive i have tried looking up power flow for these two gears and found they share shift solenoid 1 being on in both my question is could a bad shift solenoid or hard plastic harness cause this concern i am a transmission technician at a chevy dealer and this is my first ford trans i inspected every thing while dissasembled and re sealed all housings and verified by air checking i really do not want to pull this back out spoke with a buddy at ford and he said sounds like direct drum failure but i hope i would have caught that any information would be helpfull my wife has not stopped running her mouth about this
