OK, so I bought a Suncoast 6 speed conversion cheep and I installed it in my truck, My question is can I get a custom program for my setup if I still have a stock TCM on hand? truck is a 03 dually duramax.

I understand that totally, but I also still have a stock TCM and was wondering if anyone else has a 6 speed tune for the stock TCM since the original company that made the 6 speed conversion did so in 2008.

Just bumping this post up! So after all these years nobody makes a tunable TCM for the 6 speed upgrade?
