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!
