Just received refurbished tipm, all numbers the same. Mine the original last are AQ, AJ is the new one. Mine is stalling. Why I bought the refurbished. I put new one on. And no speedometer and 4x4 tries to engage halfway. How do I get "new" to one to work properly.

May have to take it to the dealer to get it re-programmed.

When replacing the TIPM, the TIPM has to be programmed to the vehicle. It’s not just a plug-n-play module/computer
