Hello I am new to the form, I am having an issue with my 1995 it was rebuilt in 2008 by Predator and has duramax Alison transmission and 261 transfer case. It just started not shifting into HL or L and jumps and surges when you start it. Feels like its stuck in LL almost like it want to dig a hole. I took it to the best transmission shop i could find inDallas and they cannot diagnose the problem they tell me it could be TCM or ECM or transfer case. Has anyone had a problem like this can you help me diagnose the problem.
