Hey guys, I have a 4l80e with a 3600 stall converter with 373 gears and a 228r cam.
Well here is the problem , the car stalls while going in reverse . If feels like I'm hitting a wall when I go from drive to reverse and stalls .. specially if I drove it around. From what I've read I need to reduce the line pressure while I'm transsioning from park to drive and drive to reverse etc... any clue how I can do that with hptuners ? My os is 1252069
