first where are you located someone in your area might have HPT....also did you make sure the shift lever was in the same position as the tranny when you hooked up the cable?

You need to get an 80e overlay installed in the PCM or a 3/4t PCM with the 6L/80e tune already loaded in it, factory tune image with the VATS disabled. Many places like CarQuest can load a factory tune in your PCM. Go onto Ebay or Autotrader and find a VIN for a vehicle with the 6L/80e and have them load the tune for that vehicle. You could contact NelsonPerformance and they can overnight you a tuned pcm.
