I was a bit nervous about replacing the TCM myself, but this programmed unit for the 2008 GMC Envoy fit perfectly and worked right out of the box. Installation was straightforward, and I didn’t need to fiddle with any extra programming or settings, which saved me a lot of time. My transmission shifted smoothly immediately, and the check engine light stayed off, which had been a concern before. Shipping was faster than I expected, arriving well before the estimated date, and the support team was quick to answer my questions when I called. Overall, a great purchase that brought my SUV back to peak performance without hassle.
