GM confirms 2015 Silverado, Sierra to get 8-speed automatic

When viewed alongside the next Ford F-150 and the Ram 1500, there is one thing that seems to be missing from the Chevrolet Silverado and GMC Sierra. Where the F-150 will rely on turbocharging and aluminum architecture and the Ram sports an eight-speed automatic and an air suspension, the General Motors twins lack a big, calling-card feature. They're very good, very refined trucks, but one could argue that they're not terribly innovative.
And while it might not be as flashy a feature as air suspension or a lightweight skin, the Silverado and Sierra will get their own eight-speed automatic for 2015, a transmission that will be paired with the company's Ecotec3 6.2-liter V8. The new cogswapper will also find its way into the GMC Yukon Denali, but for now, there's no indication why the Cadillac Escalade, Suburban, Tahoe and standard Yukon are being left out.
According to GM, the new gearbox is about the same size and weight as the current Hydra-Matic 6L80 six-speed. By the time the new powertrain combination enters production late this year, the EPA will almost certainly have gotten around to certifying the vehicles' fuel efficiency. Until then, feel free to speculate. The current Silverado with the 6.2 and six-speed auto returns 14 miles per gallon in the city and 20 on the highway. How much do you think the eight-speed will improve those figures? Scroll down for the official press blast from General Motors, and then head into Comments.

GM ending stop-sale order on heavy-duty trucks

General Motors responded to an inquiry from Autoblog regarding a stop-sale order on its full-size heavy-duty pickup trucks. Here's GM's official statement. GM is committed to building the highest quality products possible. We paused delivery on a small number of HD pickups with the 6.6 liter Duramax engine last week to finalize an investigation into a potential quality issue. The investigation has been completed and the stop sale will be lifted for the small number of vehicles at dealerships.Customers can be assured GM’s heavy duty pickups are covered by a 5 year/100,000 mile powertrain warranty. The original article continues below. General Motors has reportedly sent its Chevrolet and GMC dealers a stop-sale order that applies to some examples of the 2022 Silverado HD, the 2022 Silverado MD, and the 2022 Sierra HD. The units affected by the stop-sale order may develop an engine-related problem. Citing anonymous sources, website GM Authority wrote that the Duramax 6.6-liter turbodiesel V8 in the affected trucks can hydrolock, which means liquid could enter the cylinders and cause a substantial amount of damage. The report does not specify where the liquid would come from; hydrolocking can happen by driving through a deep puddle of water, for example, but a large amount of coolant can cause it as well. The publication adds that the stop-sale order was assigned internal reference number N222362910. It also notes that the trucks included in it can't be sold, delivered to buyers, traded with another dealer, sent to auction, or even used for demonstration purposes until further notice. Earlier in April 2022, GM Authority reported that General Motors planned to buy back an unspecified number of Silverado HD and Sierra HD trucks due to quality-related issues with the 6.6-liter V8. Details about the problems experienced by customers haven't been released; all we know is that each truck will be replaced, though the replacement may not have the same equipment due to the ongoing chip shortage.

2022 GMC Sierra Denali Ultimate Interior Review: Better by a million miles

We were right. So were customers. Basically, everyone who took one look at the interior of the current GMC Sierra/Chevrolet Silverado generation and immediately went "not good enough." Possibly followed by "not even close" and/or laughing. The Silverado cabin was especially egregious in the top-of-the-line Sierra Denali, which slapped some token bits of "wood" to the doors and center console sides and called it a day. It didn't even get the Silverado High Country's bronzey trim surrounding the touchscreen. Absolutely nothing about it said, "I am competitive with just about any Ram 1500 or, to a lesser extent, a Ford F-150 King Ranch or Platinum." That changes with the 2022 GMC Sierra. Do I really need to explain why the "After" (up top) is so much better than the "Before" (above)? I do not. The better question is: is it better or at least as good as the Ram and F-150 now? Yes! And! GMC actually upped the game further for 2022 by adding a level beyond the Denali: the Denali Ultimate. While both Denalis share a common design with each other and the also-new Sierra AT4X, that design is different than what you'll find in other Sierras and every redone Silverado. Please correct me if I'm wrong, but this is the first time the Silverado and Sierra have had such substantially different interiors. True, they're still awfully similar, but by GMC/Chevy standards, it might as well be night and day.  You can see the difference below: Denali Ultimate left, Silverado High Country right. Is one design better than another? I don't think so, but they are indeed different, which is great. BUT! Remember, this is the new Denali Ultimate we're talking about here. That means it goes beyond the regular Denali.  First, this "Alpine Umber" color with "Forge perforated leather seat trim" is only available on the Denali Ultimate and the only color available for the Denali Ultimate. It has a bit of the King Ranchy/Long Horny feel to it without going so far into cowboy land. I dig it. The regular Denali offers Jet Black or "Atmosphere/Brownstone" (shades of brown).  This leather then features white piping and super-cool baseball-ish contrast stitching. I would like to reiterate at this point that the Sierra Denali's previous idea of a luxury aesthetic upgrade was strips of wood-looking plastic. What's the word I'm searching for? Ah yes. "Effort." But wait, there's more!
