I want to do the 45RFE / 545RFE upgrade on my truck so I’ve ordered the RL041504AG Transmission Control Module for my truck. Is there a specific removal and installation procedure for the TCM? Do I need to do more than just disconnect the battery before I R&R the TCM?
I ordered the part today and it should be here no later than Tuesday. I've been thinking I may let a friend that's a Mopar tech do the job. That way he can scan and check to see if the TCM needs to be flashed.
