I have a 2011 chevy 2500 ltz z71 d-max
It has an EFI live with T&K tunes programer on it and exhaust, other than that pretty much stock.
While leaving a parking lot. Started truck, placed it in "Reverse" to back out and noticed shift indicator light was out. Placed it back in "Park" and then "Reverse" again to look for shift indicator light, and nothing. The truck took a second and then kinda jammed into gear. "Service TCS" light and "Service STABILITR" light came on. While trying to limp truck back to the house, I discovered it was now stuck in second gear. When I got home, I plugged in my programmer to read DTC code U0101, which is "Lossed communication with TCM"
Does anyone have any experience with anything similar?
