My VIN was not in the range of vehicles covered on the special coverage. I called GM and was able to get it covered 50/50 with the dealer. Turned out costing $240 to have transmission wiring harness replaced.
Is there a way for me to see the special coverage note? I'm having this issue and was told there was no special coverage. I have a 2015 Sierra with the 6.2L. I was quoted at $1225.
