Unfortunately for me the dealer performed the VB6 recall WITHOUT my permission, and I have it docummented that I refused the recall. The truck was in the shop for the latest TCM flash for the bucking when upshifting from 2 to 3rd, and I explicitly explained I only wanted the TCM update. If I have any problems with the VB6 virus, I will lemon law the truck. I went through $10K dealing with the reflashing of my 07 C&C, in 2009, due to surging when in regen, after it was reflashed to the latest engine recalibration for the early 6.7. I never had any issues with my C&C until the refresh. At first, the dealer thought it was a bad throttle position sensor. The surging was so bad, it took out my stock clutch. I had to convert to the SMF and a dual disk clutch to hold the power when it surged. If I had my foot on the throttle when in regen, it derated the HP untill it hit 2K rpm, then it would take off like a bat out of hell and would stay at full throttle for a second or two. Even if I stepped on the clutch it would just peg max rpm for the second or two. I will not put up with this a second time, they will keep getting the truck back until resolved or bought back. I have only driven it 25 miles since the virus. I'll post any problems, if any here in this thread.
