I understand the perfect transmission doesnt exist for these trucks. The OP just stated he was saving for firepunk setup. Wanted to give him some potentially useful insight is all.
The ideal transmission is an auto, and does have a neutral clutch for every time the vehicle stops. Locking the TC upon the first shift.
I was aware that autos in gear use a lot more fuel than just idling in neutral, I've always thought that was a way to save a lot of fuel. In neutral my CTS2 shows 0% load, in drive sitting still, it shows 5%.
Back draining the torque converter at a stop would lessen the load dramatically, but that would be like driving a space shuttle at that point. Your truck would be impossible to drive for anyone else.
So many things about transmissions to gain and you see it in modern cars. They gain more efficiency from playing with the TCM than with the ECM. Fact.
