Where is the transmission control module located on a 2007 GMC Sierra?
The transmission control module is usually located at the rear of the transmission case, precisely under the cover. It is located below the engine control module. On some models, it can also be found under the hood near the battery or under the interior center console.
Where is the TCM on a Silverado Sierra?

Is there a bad TCM, BCM, or ECM?
I have access to an ECM, PCM, BCM and TCM from a 2007 Sierra that I can try swapping over modules to help troubleshoot the problem if they are compatible. I have replaced the battery and cable ends and left the battery disconnected for 30 minutes hoping the ECM might reset itself, but that would just be too inexpensive and easy. FAIL!!!
What are the symptoms of an ECM failure?
Nowadays, those functions are controlled by three computers: Transmission control module (TCM). Today, we’re going to take a look at the most common signs of ECM failure. These ECM failure symptoms can be your first warning of serious engine trouble, so it’s important not to take them lightly.
When did I replace the engine on my Sierra truck?
I plan to spend Father’s Day trying to get my truck home (hopefully by driving it and not paying a ridiculous tow bill). It’s a 2008 Sierra 1500 5.3 J-code. The AFM disaster caused me to replace the engine in October or I would have already traded it in.
