    1996 Ram 5.9 NV3500 Swap

    Hi all
    Did an NV3500 swap on my 96 Ram. Having trouble getting rid of code P0743 even though all P07XX codes are disabled. Any ideas why this code won't go away? Light stays off but code stores in memory.

    ether private message or post your tune file and i will take a look at it and see if we can convert it over to a manual file if not you will have to swap to a manual trans computer and just copy and paste all your changes over to the new pcm.

    What was the resolution to this? I'm in the same boat with my 98 dakota.

    Here's my current tune. Haven't bothered with it much since I don't have to pass emissions, but it would be nice to get the code to go away.

    thats the same with my truck you can disable to light from coming on with the code but i havent found a way to disable the code from setting when scanning im still fighting to find my evap leak and do a vin write to the abs modual due to vin mismatch from having a different pcm in my 01 dakota then i will work more on finding a solution.
