Thanks for the link ph, I'm going to save it.
I noticed that the 5.3l and 6.2l vehicles have about the same tow ratings, different rear gear ratios however. I would have thought that the powerful 6.2l engine would have a higher rating?
I also noticed that the Chevy Tahoe information has not been updated only GMC and Caddy

I think the Tahoe hasn't been updated because the powertrain hasn't changed. The Yukon Denali and Escalade have the new 8speed transmission so the numbers changed a little.

If I had to guess I would say that the improved fuel economy of pairing the 8 speed with the 3.23 gearing was considered more important than potentially increased tow ratings by sticking with the 3.42 gearing. Honestly, without a suspension upgrade to handle the extra tongue weight, added towing capacity probably wouldn't be useable.

I read that the Tahoe LTZ would be the only model that would get the 8spd of the Chevy line up.
In other words only the high end models would get the new transmissions at first. Maybe someone at GM changed their minds?

For 2015 the only vehicles getting the 8 speed are ones with the 6.2 liter. I'm assuming the 8 speed will eventually cover the whole engine line. It's the same progression they used with the 6 speed rollout. If I were to guess I'd say we'll see 2016s around the middle of next year with the 5.3 and the 8 speed but it could be longer.

GMC has updated its website with information on the 2015i model.

Looks as though fuel economy remains unchanged. Oh well. I was hopeful it would be better but I'm not overly upset about it as I was only really expecting 1 or 2 mpg increase.

Clicky

Cool so which one did you order? 2 or 4 wheel drive?
Color? Wheel size?
What can I say, I'm curious.

I ordered Silver with Coca/Dark Atmosphere interior. XL, 4wd. Standard 20" wheels. I really like the look of the 22" wheel option but several of the reviews I read noted a harsher ride with the thinner rubber. I opted for cushier.

Otherwise it's pretty loaded with the open road and luxury packages.

Sweet!
I just upgraded to 22 inch wheels from the 2015 model Tahoe, it had 20s. I honestly can't tell any difference.

Those are some slick looking wheels! I may end up doing an upgrade later. Given that they didn't need to be factory installed I figured I'd wait.

Newbie here

We're just starting to investigate so a little help would be appreciated

Never towed anything but a root tiller before
Looking at 19-26' air range, but also need a tow vehicle

Unless the consensus is gm's rigs are inferior to ford and dodge, I'm
going to get a chevy or gmc since I've got a couple thousand bucks accumulated on my gm card

So with this new tranny (which will be paired with a 6.2 v-8?) will it be enough to tow a wet weight 25-26 footer?

Will it be too much torque, someone bent their frame or axle?

We live in Bay Area so everywhere we go involves scaling some steep mountains Want enough giddy up so I can do at least 60 mph uphill

Truck or SUV? Make any difference as towing rig?

Anything highly recommended I should get factory installed, special brakes,
type of tow package, type of tires, other options or accessories?

Thanks for input

I would not be surprised if the Caddy version has less payload due to all the "glitz" items.

I would think the Yukon Denali would do the job just fine. As for the new transmission, it was designed to handle the extreme torque of the new supercharged corvette so the 460 in the Denali shouldn't be a problem.

Here's an article that might interest folks. http://blog.caranddriver.com/theyve-...kups-and-suvs/
