Joe, I def can check fuse 16 today and get back to you, where is the TCU harness, hopefully somewhere simple?
Well if I did need a new TCU, that would be 100% warranty I think, since it's directly related to the transmission, hopefully?
Also, do you think I could be on to something with regards to the brake switch issue and cel and the OIL AT TEMP Light?? They have to be related somehow since they started at the exact same time.
The bad part, I wish I was able to pull TCU codes easily but I hear it's a pain in the ass and the dealer should do this as part of the warranty work as it's related to the tranny, which is still under warranty.
