I have 500 miles on my 2020 Denali 3.0 Duramax 10 speed transmission, and love it! What a beautiful ride and truck! Traded a 19 Silverado RST with the 5.3, 8 speed ( junk transmission)! It had 11,900 miles whan traded and I hated the ride and side stepping over bumps! I also have a car fax certified 2005 GMC 3500 dully with the Duramax 6.6, and Allison transmission with the original engine and transmission and the miles are on car fax to prove it is 957,500 Today. Still runs great!

I am hoping to get a lot of miles on this new 3.0 baby Duramax, but 957K on a 6.6 Duramax is unheard of! It’s first owner towed new campers to dealers all over the US, and traded it with 845K, so my son is the second owner. The carfax shows the first drivers yearly driving average to be 123K, and now it gets 12K a year! I myself wouldn’t believe it if there was no clean carfax! The original always had it serviced, and said it’s the original engine and Allison tranny!
