I just go EFILive and every tune i put in even the ones that say they are safe on stock trannys keep blownin my limp mode. Plus even before i put any tunes on my truck i would have to drive around in tow/haul mode because it would always slip so much. So i was just wondering if anyone had any good tranny tunes for a 03 LB7 5spd that would help get the power to the ground and stop throwing codes.

Thanks,
Johnny

I think u need a new tranny if its slipping before tune...

The smart thing to do is to remove all power adders if you can hardly drive it, not continue to beat on a hurt transmission.
