Tuning tow/haul mode In a truck. Does anybody know what changes you or a tuner can make to tow/haul mode. I know from the factory it has different shift points and tranny line pressure. I was thinking about turning my tow/haul button into a race button...or something to that effect.

Yup, it can be done... A lot of the "noticeable" parameters can be set to two modes....
WOT shift RPM.
Upshift/downshifts speeds/rpms vs tps at cruise.
TCC lock/unlocks.
Shift times
Shift pressures.
Torque reduction on the upshifts. (TM)
With my truck, the line pressures were the same for both modes. I'm not sure if that was different in the older trucks.
