There is no comparison from the trucks of the 2000's to the trucks between 2010 and 2021. Just like there is no comparison between the 1990's rigs and the 2000's. Things just get better............Well, except for the late 70's and 80's, things got pretty bad during those dark days!

Are the new GM diesels only available with the 10 speed powershift transmissions?

Why would a 10 speed be needed behind a diesel in a pickup annyways?

Behind a gas engine yes.


They are not needed.

I have the RAM Companion puck hitch. It’s the biggest of the big three. No pry bar or hoist is needed. It breaks down into two PCs. Not hard to separate and remove one pc at a time!!!

THe Duramax is only available with a 10 speed speed Allison (branded) transmission. I've never heard of a transmission in a GM truck called a "powershift transmission."

I have an 05 with 45K miles. I don't really need a new one but I've been bitten by the "new truck bug". I can't find what I want so I think I will have to order as well. I just need to get over the sticker shock. ENJOY your new truck!!!



We have an 05 chev duramax with 114K miles and still feel I am driving a new truck. We could drive a new truck but why?

Right on Chevman!
Of all the mid 2000s diesel pickups, the GM is on par or maybe preferable and the drivetrain is the best hands down total package.
Your LLy I think you can program in a turbo brake as well.

At 7000 miles a year your 05 has been barey used and I'm sure it a good truck.
However a 2021 is a far superior truck to your 05. More power , more comfort,10 speed tranny, more capacity.
There is really no comparison between a 2021 and a 05.
I upgraded to a 2019 from my 07. My 2019 is far noticably more capable than the 07. A 2021 with a 10 speed tranny is a step above my 2019.

I have seen Larry’s truck. It’s showroom condition and does every task he asks it to do with ease.

"Powershift" would be a good marketing name for a pickup transmission - no, but wait, the internet would immediately start comparing it to a 1968 Powerglide...

"powershift" is a generic term from ag tractors of the last 20-30 years or more - multispeed automatic transmissions 6-8-12-15-16-24 speeds- to allow small on the go changes in travel speed while maintaining constant engine rpm when running power take off driven pull type or mounted machinery. Now they have CVT behind 600hp engines...

Seems like excess complication in a powerful diesel pickup truck with their flat torque delivery.

Maybe the "PowerStroke" should have a "PowerShift" behind it???

They have a "Torqshift" transmission.

My Fird 3 fitty gas has a 6R140 "Torqshift" trans - I'm told it is the same trans as the diesel trucks, doesn't matter I'm not changing it ...

It works plenty good behind the "Boss 6.2" (don't you love the names?)

"Tranny temp never got above 175."

There was some discussion on a different recent thread about Ford preventing the gauges from telling the truth, basically reducing them to idiot lights. Now I wonder how many brands do that.

Regardless of that, I am glad that you are happy with your new truck and hope that it keeps you happy.
