Base model for work

Great truck. At about 15-20K miles it began a transmission torque converter shudder that got progressively worse. Initially the dealer replaced the tranny fluid...don't do that, just an expensive waste. Replaced the torque converter and 90K miles later, no issues. I have had other GM trucks, my favorite a 2002 Silverado 4x4 Z71 with crew cab. Rode like it had an Oldsmobile suspension with a real truck feel. Always had the 5.4 V8. My present Sierra I opted for the V6. I was very surprised at how much it feels like the V8.

Very good

I love the truck. Runs smooth and pulls great. The only thing that is bad is everything goes through the radio. Connect to phone at bad times, radio comes on because of phone when I do not want it to. But this is with every newer vehicle now I guess. Otherwise this is a great truck.

2020 elevation 3.0 duramax

I went from a 6.0 2500 Hd gas Denali to this elevasion and I can not express how impressive this truck is! If you are looking for a truck to do some pulling of atvs or whatever this thing is crazy good! I average 20 mile to the gallon around town and pulling a 20’ trailer with atvs going to mountains I seen 23 miles to the gallon! These trucks are truly amazing and have plenty of power!

2020 GMC Sierra 1500 Crew Cab Elevation

After researching between GMC & Chevy I didn’t need to decide ... GMC did that for me. I knew the style, color and it was hard to find because they were, and are, selling fast. This is my 2nd GMC Sierra 1500 that’s new off the lot. From family and friends and coworkers, even my mechanic are impressed on the quality, engineering and innovation of this 4 cylinder in-line turbo. We will be seeing many more of these on the road!!!
