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.
