I am trying to verify I have the most up to date flashed TCM and the dealer told me it does not have a TCM that the transmission (AW4) is controlled by the ECM my model year??? I was quoted 331.62 for part number JR007842 and told that was all they could do for me. I have read on several other posts that there is an issue with older TCMs with Bump Shift and the use of newer transmission fluids and as I have a new transmission being put in (got 230000 miles out of the last one, god rest its soul), I want to make sure all is well for my new Mopar Transmisison. I basically want to know if the dealer is blowing smoke and trying to sell me a new ECM or if this is right and if anyone has found it to work to resolve issues out their Jeep...
