Im assuming whatever you purchased will read TCM codes, which is key on an Allison truck.
I don't mean to burst your bubble, but my diagnostic tool also does my 2007 Ranger and any domestic U.S. car/truck up through 2010 that uses OBD2. Diesels, gas, etc. I can also buy updates to get to current if I want. It will read and deal with airbags, body control modules, A/C issues ad nasueum.
Maybe you should have asked what I had before speaking out your a**.
Some of the 04.5 and 05 GMC and Chevy Duramax Allison trucks were notorious overheaters. GM lost lots of lawsuits on them. Due to health issues at the time, I was not able to get ours back into the mountains to film the heat issue and beat them in court and force a buyback.
So I fixed mine. This is part of the fix below.
There is something wrong with the OP's truck that needs diagnosed. A lot of these trucks change hands when the problems arise and the new owner gets stuck with the problem. I have recently spoke to a person that didn't know get stuck with putting in 6 injectors on a 2002 and another one surfaced and got bought that had bad head gaskets.
A head gasket job is 600 to 1000 to do it yourself and 4000 to 5000 at the dealer. Transmission issues can be equally expensive.
People that don't understand these trucks, or don't care can hurt the 04.5's and 05's very expensively.
You made no mention of whatever you purchased having the ability to read all the vehicle modules. So my assumption was an oversight, not @$$ spewing like you with your generalizations and out to lunch dollar figures on repairs for these trucks. The overheating trouble that very select LLYs go through is typically attributed starving for air and has very little to do with the cooling system itself. This is why the most common fix is an LBZ mouthpiece.
