2004 cadillac starts and when I try to put in gear, engine dies. Happens over
and over. Is my gas cap bad? Keeping getting same error code about check
A gas cap won’t cause what your getting, this sounds like a locked up torque converter or the TCM has the lockup solenoid energized all the time. Either way it’s a big job at a tranny shop.
I ran self diagnostic and no codes about this on 2004 Cadillac DeVille. Shouldn’t it show a code to help with resolving? If no codes, what am I to do next?
A locked up torque converter will not show a trouble code.
