Hi guys, having really weird issues with my truck. Its a 96 F-350 with a fully rebuilt 7.3 and rebuilt E4OD. Truck is running really funny. It will lock the torque converter at slow speeds and if you come to a stop it will kill itself. It doesn't do this all of the time, but occasionally and has gotten much worse over the last week. I think the PCM has gone bad. Its a calibration number 6-90A and I cannot find a replacement in stock anywhere. I have heard it can be replaced with a 97 PCM but I am unsure. Suggestions??

 

Sounds like the TC is staying locked. Try shifting to N and see what happens
