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 6.2L V8 claims most powerful light-duty truck engine title

General Motors has officially captured the horsepower crown for mainstream pickup trucks with its 6.2-liter V8. The big mill, available in both the Chevrolet Silverado and GMC Sierra, comes to market with 420 horsepower and 460 pound-feet of torque, handily outdoing its two cross-town competitors, Ram (5.7-liter V8, 395 ponies and 407 lb-ft) and Ford (6.2-liter V8, 411 hp and 434 lb-ft).
The new GM 6.2 will take a bit of an investment, though. Those that want the extra thrust will need to go with either the LTZ or High Country trims from the Chevy, or the SLT and Denali trims from GMC, which are the two highest trim levels for the respective vehicles. Trim levels aside, if you're in the business of towing, GM has you covered. Optioned with the 6.2-liter V8 and the Max Trailering Package, owners will be able to pull 12,000 pounds, a hugely impressive figure.
We still aren't certain as to what sort of economy the new engine will get, but it'll probably be a bad bet for the fuel conscious. As for availability, expect to see the 6.2-liter trucks in showrooms later in the fall.

Satisfaction with dealer service rises, Lexus and GMC are tops

During the economic downturn, many car dealerships counteracted their slowing income by focusing on things that would set them apart from competition - things like the quality of customer service they provide. When the economy picked up and more sales and service followed, many also first invested those funds back into the business, improving their dealership facilities and service centers.
It looks like those investments are paying off, as J.D. Power and Associates' latest Customer Service Index Study shows that overall consumer satisfaction with dealer service has increased to 797 (on a 1,000-point scale), up from 787 in 2012 and 29 points higher than the score in 2011. The study also finds that people are more satisfied with the service they get at dealerships compared to independent service providers, despite the much higher average out-of-pocket cost per visit ($118 vs. $44).
Note, however, that this study only looks at how people are treated by a dealer's service department during the first three years of ownership (the survey is based on responses from 91,000 owners and lessees of 2008 to 2012 model year vehicles), so we're talking about the experience had when bringing a car in for repair or maintenance work, most likely under warranty. In fact, maintenance work is increasing in share and accounted for 77 percent of service visits (up from 72 percent in 2012 and 63 percent in 2011). This helps explain why customer satisfaction has also risen, since a properly maintained car is one that's less likely to require a dealer visit for an unexpected repair.
