I've got a 2014 2500 with the 68RFE. I replaced the valve body with a revmax unit, and the truck has a tuner on it, which includes transmission tunes.
Driving around normally, I have no problems.
When I put it in tow/haul mode, it holds 3rd gear for what feels too long, and the slams into 4th really hard. I tried babying the throttle before it shifts, but it still happens.
Is there something that can be done on the re-learn to help the tow/haul shift points?
The trans tune is 4th gear TC lock normally, but 2nd gear TC lockup in tow/haul.
