MotorOps TCM Tuning

Since TCM tunes truck applies power more consistently and predictably. Much easier to drive around town and highway manners ate worlds better

The 05 Duramax transmission has never been smoother. Thanks Tune Supply Shop!

The calibration I received for my 2.8 LWN was spot on. Great power delivery, the TCM tune fixed all the hunting for gears and TC lockup issues.

Very happy. My truck doesn't just dump gears and now you can stay on the boost and build some power
