Question about Hummer H3
I have the same problem. Been back and forth with the dealer and GM. Everyone knows this is a problem but Hummer will not reprogram the computer. It was suggested to me to get a vortex to adjust the computer shift points but the unit is $400 and will void your warranty. Sucks big time
