Have it at the transmission shop and he is trying to do test on it and it keeps saying it’s overheating and goes into limp mode. His snap on scanner says the temp is...

    Lbz transmission trouble

    Also the communication problem was a bad pin connection in the glow plug module

    Lbz transmission trouble

    The guy that my kid bought the truck from said the transmission was built to withstand the engine. But that doesn’t mean anything to me. I guess I’ll have to pull it and see what’s going on inside

    Lbz transmission trouble

    The truck was in the shop early this week and found the communication problem. Still shifting like crap. Took the efi live program out returned ecm to stock and re flashed the tcm. Shifts better for about ten minutes then starts slipping between 2-3 and 4-5 and hard downshift into 1st. Still no...

    Lbz transmission trouble

    Lbz transmission trouble

    I will definitely try anything at this point. I’m not sure why I’m losing communication with tcm and I don’t have the problem every time. Would it throw a code if the piston went bad?

    Lbz transmission trouble

    Would that cause hard downshifts also? I just believe it is an electrical problem with the info that is going thru the tcm. I pulled the pan last night and it looks great no metal or anything on magnet. It’s like it’s in limp mode or something. The pressures are jacked up like 175%. I’m...

    Lbz transmission trouble

    I’ve checked the power and ground pins they were good. How can I check the piston. There is no codes. I did pull the electrical plug on the back of transmission and it was full of tranny fluid. I have the pass thru plug on order
