I have a 2003 chevy with 4l80e swap in it. The problem that i am having is after i have driven the truck long enough to get the tranny up to 180deg. when i put it into reverse it feels like the truck wants to run away in reverse an if i hold down the brake it stalls the motor. after that happens i start it back up and reverse works fine. no stalling of the engine. has any one had this happen?
