I have a 1996 F250 with the 7.3 with an E40D tranny. I stripped out the front planet so I replaced it with the steel upgrade and installed a rebuild kit. While reinstalling the trans I did not have the torque converter seated properly. When I started the truck the motor turned over slow but started and made a hell of a racket! I figured I trashed the torque converter so I dropped the trans and replaced the torque converter new. I seated everything properly this time and reinstalled the trans. The truck started like normal, no noise. When I put into drive the truck didn't move. When I revved the motor (2500rpm) it slowly started to move. I went through all the gears and the same result. I drove the truck to see if the maybe something wasn't primed. When I got back I noticed the od light was blinking. What I read through this forum was that this was probably a code for trans slipping or overheat and it was most likely the torque converter? My question is, is it possible that I damaged the pump when I installed it incorrectly the first time? I did check to see if the gear was worn when I installed the new torque converter and it appeared to be fine but I'm not sure if the case was damaged inside. Everything I've read says the torque converter but unless I got a bad one (auto zone) I wouldn't think that the case. Any help would be greatly appreciated!
