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.

2020 GMC Sierra HD pricing announced

Just as with its Chevy twin, pricing for the 2020 GMC Sierra HD has been revealed. Unlike the Chevy, though, prices haven't dropped across the board. The ultimate base prices for the 2500 HD and 3500 HD are technically less than the 2019 models at $37,195 and $38,395 respectively, but that's because those are the reintroduced regular cab models. Matching up the body styles of the last year's cheapest Sierras with their new equivalents, and the prices have crept up a few hundred dollars. But the next highest trim level, SLE, drops in price by nearly $2,000 between equivalent trucks. Equivalent SLT trucks are up nearly $2,000 each, though, and the base Denalis have gone up by about $7,000. This is due in part to the 2020 Sierra Denali no longer being offered with two-wheel drive. Comparing the old and new four-wheel drive models, the price is still up by about $4,000. While the new Sierra HD is only more affordable than the last one in certain circumstances, they all feature more capability. The standard 6.0-liter gas-powered V8 makes an extra 41 horsepower and 84 pound-feet of torque than the old one for a total of 401 horsepower and 464 pound-feet of torque. The 6.6-liter diesel V8 still makes 445 horsepower and 910 pound-feet of torque, but it now gets a 10-speed automatic transmission. Maximum fifth-wheel towing has increased, too. For the 2500, that number jumps from 15,400 pounds to 18,500 in the new model. For the 3500, fifth-wheel towing goes from 23,100 pounds to 35,500 pounds for the new truck. And of course, you can get GMC's fancy MultiPro tailgate on the new Sierra HD. One final note on the Sierra HD's pricing: it has the highest base price of the full-size heavy duty trucks. The Ford F-250 Super Duty is the cheapest at $34,745 and is closely followed by the Ram 2500 at $35,090. The full range of GMC Sierra HD pricing is listed below: Sierra 2500 HD Regular Cab Sierra: $37,195 SLE: $41,595 Double Cab Sierra: $39,795 SLE: $43,595 SLT: $52,195 Crew Cab Sierra: $41,595 SLE: $45,395 SLT: $53,995 AT4: $59,295 Denali: $65,295 Sierra 3500 HD Regular Cab Sierra: $38,395 SLE: $42,795 Double Cab Sierra: $41,195 SLE: $44,995 Crew Cab Sierra: $42,795 SLE: $46,595 SLT: $55,195 AT4: $60,495 Denali: $66,495 Update: The estimation of price difference between 2019 and 2020 Sierra Denalis has been corrected. Additional clarification of Denali price changes has also been added.

GM cars and SUVs recalled for leaking transmission fluid

General Motors is recalling more than 194,000 vehicles from 2018 to 2020 due to transmission fluid leaks. The leaks stem from an auto stop-start component that may have been installed with loose or missing bolts. The leaking fluid can affect the transmission's performance, and if it leaks onto a hot exhaust component, could potentially cause a fire. GM says that to date, it knows of no accidents or injuries related to the defect. The issue affects models from all four GM divisions. From Chevrolet, the affected vehicles are: 2018 Malibu, 2018–2019 Cruze, 2018–2020 Equinox, 2018–2020 Traverse, 2019–2020 Blazer At Buick, the following models are included: 2018–2019 LaCrosse, 2019–2020 Encore, 2019–2020 Enclave, At GMC, the recall includes: 2018–2020 Terrain, 2019–2020 Acadia Cadillac has two affected vehicles: 2019–2020 XT4 and 2020 XT6 The recall is scheduled to begin in mid-December. Owners of the affected vehicles will be contacted. Dealers will inspect the transmission accumulator, and replace those with loose or missing bolts.
