I already have the Modified Stock tune installed on my truck with the AFM off only. I want to reduce the TM now.

Do I need to revert the truck back to the stock tune and then rebuild the Modified Stock Tune with AFM off and TM reduced or can I go in and just reduce the TM? It is as simple and going to the adjustable parameters, reducing TM and installing? Do I need to "reinstall" the ECM tune or just need to install the modified stock TCM tune and it combines both?

That is for the 6-speed. I have the 4-speed.

The 6-speed tune it's either on or off. For the 4-speed trucks it's a percentage and not an On/Off function. I believe it's either +20/-20 on the adjustable parameters for the 4L60E.
