I ordered the 12636006 ECM for my 2009 GMC Sierra, and the whole process was smooth from start to finish. The unit arrived quickly with free shipping, which was a nice bonus. I was pleasantly surprised by how well it was already programmed to my VIN—no extra hassle on my end. It fits perfectly and my truck runs like new again.
