GM Tricks Out Pickup, SUVS with Corvette Eight-Speed Transmission

General Motors is about to take the popular Corvette eight-speed transmission into an entirely new segment—one that is extremely unexpected. The American carmaker recently announced that the much-loved transmission choice for sports car enthusiasts everywhere will be available in General Motors’ full-size trucks and SUVs. While you might think that this doesn’t make much sense, but trust us—it’s a great move on GM’s part.

By replacing the outgoing six-speed transmission with the Z71 package and combining it with the 6.2-liter Ecotec3, which is available on both the Chevrolet Silverado and GMC Yukon Denali, GM has enhanced the driving experience of its big vehicles, making them smoother and quicker during acceleration. The American carmaker has also enhanced the fuel economy of the pickup and SUV, increasing the fuel rating by 1 mpg in both city and highway measurements for those models with four-by-four systems.

The Corvette eight-speed transmission will come standard on the 2015 Chevrolet Silverado, GMC Sierra, and GMC Yukon models that are equipped with the 6.2-liter V8. If you are interested in seeing this sports car transmission in a big-bodied vehicle, stop in to Warsaw Buick GMC today and give the 2015 Yukon and Sierra a test drive!

Eight-Speed Transmissions Optional on 2015 GMC Pickup Trucks

If you’re looking for your weekly dose of exciting GM powertrain news, you’ve come to the right place! GM recently announced that their new lineup of trucks, including 2015 GMC pickup trucks like the Sierra and Yukon, will pair its mammoth 6.2L EcoTec3 V8 engine to an all-new eight-speed automatic transmission, bringing you both more power and a smoother driving experience for the new model year.

The new transmission, called the Hydra-Matic 8L90, remains just about the same size as the six-speed automatic, so you get added performance without losing any under-the-hood space or fuel efficiency. The Hydra-Matic 8L90 is the perfect match for the big EcoTec3 engine, which, with 420 horsepower and 460 lb-ft. of torque, claims the title of most powerful engine in any light-duty pickup truck.

This massive powertrain also helps the 2015 Sierra and Yukon post a maximum trailer capacity of 12,000 lbs—basically, the new eight-speed transmission assures that this new line of luxurious and powerful trucks is capable of completing whatever task you set before it. It’s automatic—and so is your choice when it comes to full-size pickup trucks. Come see us at Warsaw Buick GMC today to check out these awesome new trucks.
