Just be careful. I sent GDE a Ram TCM I had and they were able to flash the non-F37 stock Jeep tune but not their own Eco tune. They had to send it back to me so I could swap it for my actual Jeep tcm.
I forgot to mention; any TCM you get needs to be out of a vehicle that has a 545RFE transmission & has a separate standalone TCM.
Probably should contact GDE and ask them for a list of compatible TCM PN's just to be on the safe side?
