Duramax Reliability

Hey guys new member here. I am looking at buying a 2500HD SILVERADO LT crew cab with the 6.6 Duromax diesel and an Allison transmission. I drive quite a bit about 300 miles a week so I am wondering what your past experiences with the reliability, maintenance costs and how many miles I should expect to get from this truck. I would also like your views on the price. Dealer has the truck its's an LT with everything but leather, 8700 miles. They want 35,500 is this a fair price? Since this would be my first diesel any insight would be great. Thanks

I bought min in Feb 06 and I have 22.5K miles on it, its been to the dealer for a 5 min recall/reflash of the computer. Other than that its been perfect!

I paid 39K brand new with every option on it. Leather, Moonroof, Onstar/Sat Radio, etc, etc.

You can check it out here.

I would call $35,500 a bit high. Great trucks though.

8700 miles what a dealer demo????? The price is right on a new truck(the one you describe), dealer told me dealer demos not worth it, and when I ran the numbers realized they arent either, sometimes they are give out as loaner cars (ie read trashed), dont always receive all rebates, warrenty already started etc.

these trucks are reliable. My LLY, which will be 3 years old at the end of march, has 163000 miles on it and everything is pretty much the original. Now my new LBZ will be seeing the same treatment as my LLY. I gave my 04.5 LLY to my dad.

I bought a new '06 LBZ and have put 20k on it in 8 months now. I've only had to have the computer reflashed to fix a powertrain shimmy, so I'd say I'm happy. Especially when it starts at -45 in Fairbanks, Alaska. I'll tell you this, the company that patrols and services the Trans Alaska Pipeline will only buy one truck to run up and down the state from Prudhoe to Valdez, and that's a GM duramax. The dodge's shell trannys and ford powerstrokes blow up. Based on friends' bad experiences and strangers i've had to pick up in the middle of nowhere while on hunting trips, i wouldn't buy anything else. I'd like to see how the new HD's do. Got mine for $39k loaded, but that's the Alaska price.
