GMC killed the 8 speed....

ShamrockShooter · February 25, 2020

Just happened to look at the build and price tool on the GMC website. The 8 speed has pretty much been mothballed on SLE and up trims unless you want the 2.7 turbo.

A crew cab GMC elevation with a 5.3 and 10 speed is going to be a nice seller.

I like my 8 speed. But that's still a kick in the shorts being it's just one year later. Few years from now when people are buying these trucks used nobody will want the 8speed trucks. I doubt they're about to put me in a 20 with a 10spd with the same payment either. Sheesh.

10 speed shifts smoother. The 8 speed has given GM lots of problems over the years.

Is this only on 4wd? All the 2wd trims 8 speed is still an option.

10 speed is limited to 4WD and 2WD diesels only.

I don’t think it’ll plunge the 8 speed values off a cliff. You figure the 8 speed was the top of the line trans from 2015-2018, and the most common trans in 2019. On the Chevy side it’s still the most common in 2020. If someone is shopping for a used truck in 3-5 years, avoiding the 8 speed is going to be pretty hard because at least half of the trucks are gonna have it.

At the end of 19MY, it was much more restricted:

It was not available on other trims.

Similar availabilities on GMC.

Given the myriad of issues, 2015-18 trucks will probably be the lowest for any type of resale value anyways.

Chevy still shows 8 speed, GMC 4x4 (not sure why you ever buy a 2wd truck...) Shows starting at SLE 5.3 v8 10 speed standard

Why not just put the damn 10 speed in all trims but the work trucks ? Why does GM play games like this.

Because according to some here, the 8 speed is a perfectly fine transmission. Just kidding .

Must be a GMC thing where GM can charge more for the truck and the transmission; 8 speeds continue to be alive and well in the '20 Silverados

Part the only reason I got an early 20 trailboss was to get the 10 speed. If I had to do it over definitely would have went for a fully loaded elevation with the 5.3 and 10 speed and probably saved a few bucks

Same deal with the K2 being all 6 speed at first then offering 8 speeds in higher trims. I suspect the 8 will hang around in lower trim levels until they are gone.

I disagree entirely. They haven't had near as many issues as many claim & they are currently holding their value quite well. If you can find one in my area, they still go for 50-70% of new.

Is this the same 8 speed that has a lawsuit against it?

I don’t have any issues with my 2019 RST except on a cold mornings, I have hard 1-2 and slip to 3 but 10 min warm up and it’s smooth all day. My build date is 02/19 so I don’t have the new Mobil ATF.

I wonder if the 10 speed has a similar issues when left under 32f overnight? (Maybe a question for another post).
