Hi, a friend had his TCM flashed by Anarchy.
Ever since, the tow/haul button does nothing.
I monitored the TCM data with a scan tool, and the TCM sees the input change but no difference in trans operation.
It also has some severe 5-6-5 hunting at times under load...as well as desired trans pressure hangs around 200 psi all the time, but actual pressure never goes much above 160 except in reverse.
His truck is a deleted 2007, but nothing crazy done to it other than a mild tune.
He isn't out beating on it or making smoke.
It uses it to pull a car trailer and a dump trailer.
Thanks
