I have pondered that also but pretty much everywhere in the engine compartment is pretty hot. My assumption is that GM located the current location with that in mind. Gates belts are my favorite and do not produce the static electricity of some others.

 

Thank you. I might be worried about nothing.

 

It's a good thought, and I had the same one. But where could it be placed that would be cool but still protected? I haven't found one.

 

Im also wondering about relocation, i just had to fork out some crazy money for one of the last new TCM's i could find online and heard some people are relocating to on top of the Fuse panel lid. and also adding a grounding strap to the TCM.

 

Grounding the case of a TCM is not a good idea. I THINK that comes from this video:

 

interesting? Whats your thoughts on relocation to prevent heat soak? My truck isnt at my house right now but when i get it back i will have to open the loom a little on the TCM and see if its even possible to get it over to the fuse block lid. I also dont want to be pulling on the harness at all actually. I have a fear of pin fitment as well as festering the harness opening another can of worms.

 

Supposedly these fail quite frequently due to heat and vibration. Also a few instances where it actually fell and gets damaged. ATS Diesel Performance has a relocation kit available that moves the TCM behind the fuse panel in the back corner on the drivers side with an extension wiring harness and a bracket. ATS also has a upgraded TCM for Duramax's, currently only 2011 and up right now.
