2015 Chevrolet Silverado Enhanced All-New Eight-Speed Automatic Transmission
DUBAI – The all-new, GM-developed Hydra-Matic 8L90 eight-speed transmission is matched with the available 6.2L EcoTec3 V-8 engine in the 2015 Chevrolet Silverado Light Duty (available on 4WD extended and crew cab models only), supporting the pickup’s capabilities with greater efficiency and refinement.
It was designed with 11 percent greater torque capacity than GM’s 6L80 six-speed automatic transmission, complementing the output of the 6.2L, which – at 420 horsepower and 624 Nm of torque – is the most powerful engine offered in a light-duty pickup.

With four simple gearsets for optimal efficiency and five clutches (two brake clutches and three rotating clutches), creative packaging enables the new eight-speed automatic to fit the same space as the previous six-speed automatic, with a lower weight. A wider 7.0 overall gear ratio spread provides a numerically higher 4.56 first gear ratio, helping drivers start off more confidently with a heavy load or when trailering.
The 2015 Silverado Light Duty equipped with the 6.2L engine and eight-speed automatic transmission will have a maximum available trailer rating of 5443 Kg (12,000 pounds), based on SAE J2807 Recommended Practices.

Smaller steps between gears, compared to the 6L80, keep the engine within the sweet spot of the rpm band, making the most of its horsepower and torque to optimize performance and efficiency. They also enable numerically lower rear axle ratios, which reduce engine rpm on the highway for reduced fuel consumption.
More than 550 computer-aided engineering analysis were made during the development of the 8L90 to ensure strength, durability, performance and refinement. The architecture features a one-piece case with an integral bell housing for enhanced powertrain stiffness.
Founded in 1911 in Detroit, Chevrolet is now one of the world's largest automotive brands, doing business in more than 140 countries and selling more than 4.9 million cars and trucks a year. Chevrolet provides customers with fuel-efficient vehicles that feature spirited performance, expressive design, high quality and outstanding value. The Chevrolet portfolio for the Middle East features award-winning passenger cars such as the Spark, Sonic, Cruze, Malibu, Impala, Camaro and Corvette; crossovers such as the Captiva and Traverse; and, SUVs and pickups including the Tahoe and Silverado. Chevrolet also offers customers a high-level aftersales service experience through Chevrolet Care. More information can be found at
