The 12602801 ECM for my 2007 GMC Sierra arrived quickly and was exactly as described. Installation was straightforward since it was fully VIN programmed and truly plug-and-play, which made the swap hassle-free. I saved a significant amount compared to the dealer’s price, and the seller’s communication throughout the process was very clear and professional. Overall, a great experience and my truck runs perfectly now.

I was really impressed with how quickly the ECM arrived—it shipped faster than I expected. When it came time to install, the unit was truly plug-and-play, making the whole process smooth and hassle-free. The fact that it was already VIN programmed saved me a ton of time and frustration. This purchase definitely saved me a significant amount compared to what the dealership was quoting for the same part. Throughout the process, the communication from the seller was clear and professional, which gave me confidence in my purchase. Overall, it was a great experience, and my Sierra is running perfectly now.
