Hey Everybody,

Ive got a 2002 LB7 with the AL5. I am tuning my TCM so that in tow/haul mode I can get it to shift into 5th gear later as Im having trouble with it slipping early while pulling trailers. No matter what I set in the tow haul part of the tables the tune still shifts at 57mph which isnt even the stock value? In the normal drive part of the tune the TCM responds to any changes I make such as making it shift to 5th at 80mph but will continue to shift into 5th at 57mph in the tow tune no matter what value I set it to. Any ideas or suggestions would be awesome. I have already reflashed the TCM as well as done the calibration tunes and still no luck. The OS of the TCM is 15079907.

Thanks,
Kyle
