I've read in a few places that it's possible to swap a 545RFE TCM with the TCM in my 01 Dak and turn my 45RFE tranny into a 545RFE. Anyone here tried that? I also read that all 4.7's in 2002 and after all had the 545RFE tranny, but it seems like the part numbers on the 02 TCM's I see for sale have multitudes of part numbers, so if anyone has a way to tell what tranny a TCM goes to by the part number it would be very helpful. It would be a bummer to buy an alleged 02 TCM only to find out it's actually for a 01 45RFE.

Did you have any problems later with your security remotes not working? I noticed my remotes stopped working after I put the Jeep TCM in. The TCM worked and shifted fine. I'm going to put the original back in and see if that is the issue.
