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.

2017 GMC Model Year Preview and Updates

GM's 'professional grade' truck and SUV specialist continues to deliver its utility-with-luxury vibe, optimized in the all-new Acadia, relatively new Canyon and continual updates to its Sierra pickups and Yukon SUVs. GMC ACADIA: An all-new Acadia - pictured above - is aimed at the heart of the midsize segment. In an unusual step, the GMC product team downsized the Acadia, dropping 700 pounds from the earlier platform in the process. The new crossover is available in four trims – SL, SLE, SLT and Denali – and an offroad-oriented All Terrain package is available on both SLE and SLT when equipped with all-wheel drive. For young families, GMC introduces the industry-first Rear Seat Reminder, a prompt which will remind the driver to check the rear seat area before leaving and locking the vehicle. CANYON: The midsize pickup introduces two new variants for 2017. The upmarket Denali adds swag – unique chrome grille, 20-inch aluminum wheels and various interior upgrades – to its swagger, while the All Terrain X provides the adventure traveler with all-terrain tires, off-road suspension, Hill Descent Control and all-weather floor liners. SIERRA: The Sierra's maximum trailer tow rating of 12,500 pounds is the best in the full-size, crew cab segment. New features include Teen Driver, active aero shutters on all models and available tri-mode power steps. Also, GMC adds two new colors to the palette: Dark Slate Metallic and Pepperdust Metallic. SIERRA HD: The big news is the addition of the All Terrain X to GMC's heavy duty lineup. With an offroad-specific footprint provided by its 18-inch aluminum wheels and Goodyear Duratrac tires, ground clearance is enhanced by the Z71 off-road suspension, and an Eaton automatic locking differential keeps you rolling. TERRAIN: While the 2018 Terrain awaits its showroom debut, the 2017 Terrain's new Nightfall edition darkens the Terrain vibe. The one new color for 2017 fails to hit a brighter note; it's Graphite Gray Metallic. YUKON/YUKON XL: Perhaps the ultimate Uber capsule, the big/bigger SUV enters 2017 with a host of refinements, including GM's Teen Driver feature, upgrades to rear seat entertainment, available low speed forward automatic braking, active aero shutters for improved efficiency and one new color: Dark Sapphire Blue Metallic. If you're looking to maximize your visual presence, consider the SLT Premium Edition, which ups the chrome content well beyond the commercial minimums.

GM recalls 330,000 fullsize trucks for airbag replacement

General Motors has announced a recall of 330,198 fullsize pickups in the US in the aftermath of the announcement made on May 19 that doubled the number of vehicles being called in to replace Takata's defective airbag inflators. That announcement expanded the nationwide recall to an estimated 33.8 million vehicles in the US. Heavy Duty versions of the 2007 and 2008 Chevrolet Silverado and GMC Sierra are included in GM's move, for the purpose of replacing the passenger airbag inflators. The announcement made by the National Highway Traffic Safety Association cited long-term exposure to moisture as a possible cause of the inflator issues. GM says it isn't aware of any problems with the recalled pickups due to moisture, nor has it had any reports of crashes, injuries, or fatalities, and has not received any complaints. GM will notify owners, who can then take their trucks to the dealers to have them repaired free of charge. You'll find a statement from GM and the recall notice from NHTSA below.
