I have a 2007 Silverado 5.3L Classic
Programmer is a U7192

I have installed the 93 tune and am having problems with hard shifting
I have reduced shift presure 10% on both WOT and Partial Throttle
The truck still seems to shift really hard

I would sure like any advice

Thanks

Try lowering the pressure to -25% at part throttle to see if this helps.

Thanks
