03 with transmission probs
Has anyone heard about service bulletin #131779? It deals with the TCM, if you are stuck in third, transmission shop replaces the solenoids and it is still stuck in third, it could be the TCM. It tells what solenoids when to open or close and is in control of the transmission. I was wondering what the bulletin is good for? Can I get a new TCM, or does it just update it?
