| Tranny problems
I have a stock 01 GMC LB7! I was going down the road and came to a stop light! I then turned left and got up to about 45 mph and it jumped into limp mode. I couldn't read the code because i didn't have my programmer with me. I let it cool down and disconnected the battery to clear the code. The code cleared and it was fine until the tranny reach higher temps. It jumps back into limp mode every time it reaches full temprature. If the tranny's cooler it runs and shifts fine. Any ideas what the problem could be? |
