U7137 TCM support for 2004 RAM 1500, 5.7 all wheel drive

Post by theboz001 »

I realize this product has been discontinued, but searching online finds instances where the 2004 TCM support will be available, then another post says it isn't.

I just purchased a Diablo Predator U7137, updated the calibration and device to 9r14. It upgraded the calibration on the truck, but it still says the TCM is unsupported.

PCM version prior to calibration update : 560828787AD
PCM version after calibration update: 56028787AI
TCM : 56028810AE

I installed the 87 performance tune with no modifications. Now when I put it into drive it take 2-3 seconds before drive actually engages. When turning from one street to another at approximately 20-25 Mph it isnt quite sure what gear it wants to be in. It feels like it downshifts, but as soon as you press on the gas it shifts up again. Double checked the fluid level to be sure it wasn't low or anything. No issues there. No shifting/engagement issues prior to installing the tune.

Searching for the TCM calibration number comes back with several saying it's supported, but for some reason my tuner says it isn't.

Appreciate any assistance possible.
