Took it to have it programmed, and no dice. They flashed the ECM and TCM, and I lost my PPEI tune. Thankfully, I have my SFT tunes on standby.
Called trans shop, and his statement was “well... gonna have to get it back here, so I can pull it back apart. I don’t even know where the neutral safety switch is...” Screw that. Left it with dealer to get diag’d.
Dealer stated used trans had internal damage. Got a refund for the new/used trans, and have a new one on the way from MOPAR. Warranty, and ability to have it checked out anywhere there is a ram dealer. Said it would take 4-5 days to get new trans, and they would call me when it was ready.
Jimmy at SFT was truly helpful. Got all my tunes turned around in record time so I could have tuned the truck before bringing home. Will flash with their tunes after I pick the truck up.
