99 chev Z71 automatric....just hooked up hypertech programmer and was not sure about trans settings.
any sudgestions on the best way to program the trans without screwing it up. does the 1-2 2-3 3-4 have to be at the same RPM shift points. im not off road that much and its seems at the stock setting that im lugging in 4th gear .
