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.

UPDATE: The trucks have been revealed. Click here for all of the official details.
As promised, Chevrolet and GMC are offering a live webcast of the world premiere for the all-new 2014 Silverado 1500 and Sierra 1500. After being teased with spy shots and blurry images like the one above for ages, now is the time to see the trucks in the metal, for real (well, as 'real' as it gets on a webcast, at any rate).
Shift your eyes down just below to see the reveal as it happens, starting at 9:30 AM EST. We anticipate having loads of images full technical information to share after the webcast, too, so truck aficionados should stay tuned. We'll also be bringing you live images of both trucks too, when we see them on the show floor at next month's Detroit Auto Show.

eBay Find of the Day: 1976 GMC Motorhome is a jolly green giant

If you have a need to relive the 1970s, then here is the vehicle for you. This groovy blast from the past is a 1976 GMC Motorhome currently for auction in Florida on eBay Motors, and it is one green machine - just not in the modern sense.
The seller claims that this beast has had just two owners and has covered a mere 61,308 miles in its decades on the road. It's reportedly never been restored or repainted and comes with all of the necessary books and manuals. A 7.5-liter (455-cubic-inch) Oldsmobile V8 with a three-speed Turbo-Hydramatic automatic transmission powering the front wheels propels this far-out RV, and the double set of rear wheels out back use a self-leveling air suspension to provide a cushy ride.
The purported low miles and good condition really make this GMC a stand out, though. The exterior combination of lime stripes and beige with just a touch of green is like nothing else on the road today. Plus, the polished bumpers and wheels make it all pop. Inside, it's even better with monochromatic green upholstery and shag carpet. It features everything you'd ever need on a long trip, including a bathroom, kitchenette and lots of seating. The only hint of modernization is an HD TV next to the stove, but its size is a perfect fit for the hole there.
