On Deceleration on like a off ramp from the highway and merging into traffic again....When you get back on the throttle the trans will free rev and slam into gear. This only happens on level 2,3,4 not 1. This truck has the off road option (DPF Delete).
Any ideas? |

I think your best bet is to get your tunes reworked by Bill. but you will need to call and talk to him in person so you both understand what is going on. hope this helps

I have had the same issue ever since I put the PHP on the truck. I believe this truck really needs a tuner that programs both ECM and tranny. I like the PHP product but without tranny tuning, this seems to occur.
