3.0 duramax/10 Speed transmission


Recommended Posts

Howdy, 

 

I'm new to the forum and I just received an email from GM saying they were going to re-purchase or replace my 2020 Silverado 1500 Custom Trail Boss due to a transmission that liked to overheat and put itself into limp mode. I'm kinda interested in replacing it with the new 3.0 Duramax and I just wanted to ask if anyone has had any major problems with the new 3.0 Duramax or the 10 Speed transmission? Any replies would be helpful. Thanks!

I wanted to get the 3.0 but it wasn't going to be available until later on and so I settled for the 6.2.  Not disappointed since I do like the performance of the 6.2 but the economy of the 3.0 can't be beat in a 1500.  I guess my 2.0 Cruze diesel will just have to do.

Just hit 2000 miles in my 2021 at4 3.0 Dmax. It has been flawless. A great drivetrain.

Good ****** man. That's the next truck I want to get actually. Disappointed my trail boss didn't hold up, but I like the way the GMC looks anyway. Plus Chevy for whatever reason won't throw the Duramax in the trail boss 🙄
