It seems like I'm getting closer to fixing my truck, but it still feels like i'm miles away.
After a lot of troubleshooting and diagnosing different things, we finally narrow part of the problem down to the TCM/transmission control module. I sent it off to have it diagnosed and fixed. The transmission neutral safety switch was also failed and then replaced. My transmission is still staying in Trans Fail-safe mode. I have a battery light that stays on my instrument cluster. I read in a another gentleman's post that his instrument cluster was the culprit. I have ATC m code coming up.
But i'm not sure the transmission has failed or is the culprit of the trans fail problem. I will attach the diagnostic report from my scanner. I had voltage tested and everything is charging correctly. The battery is brand new, but I have this crazy battery light that will not go off. It is my understanding that any problems in the charging system can create a trans fail safe condition code. We have a speedometer instrument, cluster repair shop in my city, and their advice was to swap out a good known cluster with the same part number before having them to
Do a repair that may or may not fix the battery light issue. I'm trying to get additional insight. 4 help that may get me closer to resolving this issue. Thanks in advance.
