Thanks for the response Greg. We had looked at the Next Gen Drivetrain products and when this GM repair fails, we will be looking at going that route. Just a question: why would you do the Pulse delete option? (I watched the install video and it really didn't cover the advantage/reason for doing this option)

Rear wheels lock up when it tries to downshift while towing (going uphill with our 5th-wheel RV). This is the known problem that 463,000 trucks were recalled and programed to try and let the owner know about 10,000 miles before a lock-up happens (feels like you ran over a telephone pole). Ours just happens to be one of the "lucky" ones that locks up without prior warning. We took it into nearest Chevy dealer (out in CA). After 2 weeks waiting, we were told by the dealer they didn't need to do anything relating to the recall because it wasn't throwing the PO747 error code. I offered to take a technician up a hill on the highway with our 13,000 lbs 5th-wheel in tow, but they declined. They asked us to wait in California (2100 miles from our home) for another 8 weeks for a GM engineer to come to the dealership and look at it. We declined and put our camper in storage and drove the truck home to be serviced local. We can't wait the 8-10 weeks for a GM engineer. Does anyone know who to contact at GM to get our costs covered? (note: We have filed reports with NHTSA and opened a file with the GM Customer Care line- Who told us we were covered by the recall, but because they were not part of the GM technical service (TAC), they had no authorization to tell the dealer what to do as dealers are independently owned.) Are we forced into a lawsuit to recover our repair costs and expenses for what should be a warranty repair? And imagine our surprise when we learned that despite the branding on the hood, we didn't have an Allison transmission. Reference: Special Coverage N242454441-03
