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.

2024 GMC Canyon AT4X AEV Edition First Drive Review: The business-class Bison

McALLISTER, Mont. – Not far from MontanaÂ’s Ramshorn Peak is a beautiful body of water known as South Meadow Creek Lake. It sits just a hair below 9,000 feet and offers beautiful views of the surrounding highlands and — if youÂ’re lucky and the lighting is just right — a clear line of sight to Big Sky Country. To hear the locals tell it, you canÂ’t get there in a pickup truck. Apparently, to a GMC engineer, that comes across as an open challenge. And so I found myself in the two-horse town of McAlllister (not far from Bozeman), chilly in the fog of an early October morning, inspecting a line of GMCÂ’s midsize trucks in their hardest of hardcore variations. One half of the fleet was made up of the standard 2023 Canyon AT4X finished in a beautiful scarlet red; the other half, 2024 Canyon AT4 AEV Editions in a menacing gray that matched the dreary morning sky. Yep, that AEV. The Canyon AT4X is an already-capable little trail monster with all the off-road bells and whistles you could possibly ask for. ItÂ’s a virtual mechanical twin to the new Chevrolet Colorado ZR2, in fact, down to the 2.7-liter four-cylinder that produces 310 horsepower and a whopping 430 lb-ft of torque. Naturally, American Expedition Vehicles managed to turn that dial up to 11. More on that later. Canyon AT4X 3 View 32 Photos To the locals' point above, off-road trucks have existed for quite some time (just ask Marty McFly), but it has only been since their rise in popularity as mainstream commuters that the dedicated four-wheelinÂ’ pickup has really come into its own. The “you canÂ’t get there from here” Maine attitude at Bozeman latitudes betrays somewhat old-school notions about four-wheeling — and the fact that just about everybody in town owns some sort of ATV or side-by-side. The formula used to be pretty simple: You take the shortest SUV frame youÂ’ve got, add big stick axles to the front and rear, and then jack the thing up as high as you can without it falling over at the first sign of an incline. TodayÂ’s torque-monster engines have turned that on its ear. More torque means you can turn bigger tires, and what do bigger tires do? Well, among other things, they lift your truck off the ground. Shove enough tire under a truck and no matter where youÂ’re talking about, you can indeed get there from here. At its core, AT4X isnÂ’t groundbreaking.

GM alerting truck and sedan owners to a do-over on brake recall

A recall campaign intended to address issues with braking systems on certain 2019 General Motors trucks and sedans may have introduced a new issue, the automaker has acknowledged, and thousands of owners driving repaired vehicles may need to return to their service departments for another update.  The update addresses a fix that was pushed out to owners of more than half a million brand-new GM trucks and sedans that could potentially lose partial braking function, according to the Detroit Free Press. The original software fix helped address situations where the vehicles' anti-lock braking systems would become disabled, which in turn would prevent electronic stability control from activating. Vehicles subject to the recall would often experience software glitches that prevented them from properly communicating the operational state of these systems, meaning drivers would have no idea that their brakes may not behave as expected in an emergency. The 2019 Chevrolet Silverado 1500, Cadillac CT6, and GMC Sierra 1500 were all recalled in the original campaign.  Unfortunately, the early version of this fix appears to have introduced yet another software glitch, indicating that the original fix did not do the trick. Those who have not yet had their cars serviced can rest easy; they will only receive the most up-to-date version of the software fix.  Related video
