Anytime a trailer is first attached, the truck will randomly go into reduced power mode while driving. This is very unsafe as the truck can to this at highway speed in traffic. It will do this a few times until the PCM "learns" there is a trailer attached. Gm is aware of the issue and issued service bulletin 06-06-04-042b to address the issue by reprogramming the PCM. Because of the safety concerns, this should be addressed as a recall. However,I had to take the truck into the dealer for the update and was expected to pay for them fixing a known software issue. Instead of doing the update at no charge, they managed to damage the PCM while performing the update. The PCM is no longer serviceable and the dealer is wanting to charge me for a replacement even though it was damaged during a called for service bulletin update. The vehicle was not originally equipped with a trailer hitch so the problem didn't arise until the hitch was installed and a trailer was attached.

The line running from the transmission to the radiator is extremely prone to leaking due to a weak/improper crimp in the hose. As time goes on transmission fluid is depleted and could lead to transmission failure. The leak is widespread across most allison transmissions due to a faulty hose crimp and leaks through the crimp in the hose.

My 2006 durmax diesel 2500 truck has 3 transmission cooler lines that run from the transmission to the radiator. These hoses have aluminum pieces on each end and they leak oil at the joint where the aluminum joins a piece of rubber hose in the centre. They continuously leak transmission oil on the ground at this crimp join. The colder the weather, the worse these hoses leak. There appears to be a significant problem with these as detailed by doing a web search. I pulled in my garage from a trip and a few minutes later my wife saw smoke coming from the garage. I jumped back in and backed it out before it actually caught fire but upon inspection, the leaking transmission fluid from the lines had gotten on the exhaust and started to smoke. This is a serious issue that gm continues to ignore. Someone will eventually lose significant life or property if this continues. The replacement lines started leaking in a mere couple of weeks.

2006 chevy silverado hd diesel with allison trans-- transmission cooler lines leaking, dealer said there has been no known problem. I searched online and found hundreds of similar complaints. So I was forced to pay $700 to have the lines replaced, which will probably end up leaking again. This is obviously a defect, as I have 3 other chevy trucks, none of which have ever leaked from the trans lines, and some are over 10yrs old.

My 2006 silverauto with the durmax engine and alison transmission. The transmission line have been leaking. I have 60,000 miles on it so the warranty is out. When I took it into the chevrolet dealership where I purchased the vehicle they would not cover the leaks as part of the drive line warranty. When I purchased the lines from the parts department they indicated that they were selling a lot of these hoses due to leaks. If there are this many lines leaking I think chevrolet should replace these faulty lines at there expense. Also I know of one other 2007 model that burned out the transmission due to these lines. Because the transmission failed chevrolet replaced the transmission and the lines.
