That still leaves you seven gears.

And seven gears ain’t bad!

My wife’s Caddy has that transmission. I liken it to a golf cart. The power is seamless and you don’t even notice the gears. It is mostly instant torque at all speeds and engine RPMs.

One of our work trucks has the 8 speed transmission and I agree it sucks.

If you want a long lasting truck, word on the street is get yourself an Isuzu, baw.

And I’ll add that I have a direct comparison in that she had a Denali with the 8 speed. The 8 speed was trash compared to the 10.

Not sure if enough miles to know yet, but I have a 2020 with 8000 miles, 10 speed is very nice. That's all I got.

Huge difference between the 8spd and 10spd with the 5.3L. 10 spd hauls arse and shifting is very smooth.

I have a 2020 SLT Premium Plus with the 10 speed. Love it. My dad bought a Silverado at the same time. I told him to upgrade to get the 10 speed but he didn’t and now regret it.

2020 GMC AT4 with 10 speed and 3.0L Dmax... Great power and most of time you can't tell it is even shifting. 6th GM truck and definitely the best one yet. Would recommend.

They have a TSB on the fluid in the 8 speed. It causes all kinds of issues.

10 speed is rock solid.
