    On my 05 Chevy Silverado 1500 2wd 4spd Auto 5.3V8, how can I make it not shift into 2nd gear when I have first gear selected on the gear shift? Right now it will shift into second gear at about 5000 RPM. I know that function is there to keep you from overreving the engine but is there a way to make it hold the gear I select on the gear shift no matter what? Any help appreciated!!!!

    You can change that with a Diablo Preitor or Trinity programmer. You can make the shift change with mph or rpm's.
