Overview & Reviews

For 2006, a diesel engine upgrade is the most significant change to the Chevrolet Silverado 2500HD. The Duramax 6.6-liter engine receives a host of power and refinement upgrades, as well as reduced emissions. Additionally, the Allison automatic transmission is now a six-speed, and features a tap-shift range selection mode. The only other noteworthy updates are a new design for the optional power camping/towing exterior mirrors and slightly updated front-end styling.

• Powerful engine lineup, multiple drivetrain configurations, substantial towing and hauling capacities.

• Spotty build quality, mediocre interior design and materials.

  Deadbeat Duramax - 2006 Chevrolet Silverado 2500HD
  By agmakar - May 8 - 12:06 am

  I think I bought a Monday morning vehicle. The rear differential leaks, and I get abhorrent fuel mileage. 8 MPG when towing a 7500 pound trailer and adequate mileage not towing (16 MPG) I took it to the the Chevy dealership twice for the leaking problem. It happens when driving it on the highway or towing. They added an inline filter in the breather hose, not much help, it slows the process down until the filter fills up, then it leaks out of the tube. The third time I take it to a different dealer, they replace the inline filter with a smaller one and the want to re-tap a new location for the breather tube right on the rear axle housing and plug up the old one on top of the pumpkin.

  Just dont Know - 2006 Chevrolet Silverado 2500HD
  By Eric - May 29 - 2:00 am

  Well I guess my roots run deep with GM. Got the truck used off a dealer lot with 90000 miles on it. While test driving the truck it performed and looked in excellent condition. The motor and tranny on this truck, as previous GM trucks Ive owned is stout and reliable. Now, As for every thing else well lets just leave it at that for now. Owned a 98 Gmc before this one and it was one of the best vehicles Ive owned, but in the recent years Ive heard and witness a lot of bad rap from GM and was skeptical of buying another. I guess it was the love for that bowtie.

  2nd time, shame on me - 2006 Chevrolet Silverado 2500HD

  Cannot say enough about the power of the 6.6 Duramax, handles grades up and down quite well. The seats are very comfortable, both front and rear; with three kids, it had to be. Not nearly as impressed with the finish as this is the second new GM/Chevy product I have owned in the past 12 years and both were of far less quality finish than the competition. Fortunately for GM/Chevy, it was the heart, not the looks, Shame on GM/Chevy for their lack of quality control on the exterior finish.

  Still wondering if 07 is better - 2006 Chevrolet Silverado 2500HD
  By Brian - January 28 - 7:06 pm

  This truck is is a blast to drive around, an excellent work and tow vehicle. The gas mileage however, will take a bit to get used to. The best this truck will average is about 12-13 mpg, and that is unloaded and using the gas pedal with a light foot. However, this is a truck that was designed to work and perform. If you like to off-road be careful. Although it may look capable looks can be deceiving. The rear end differential has a very low clearance height to the ground. Any kind of rutted off-road will pose a challenge if there are any obstacles on it like small rocks or stumps. Even at the beach you will hear some awfull scraping and thumps. Bad fit and finish!! didnt notice until at home.
