10L90 Transmission

The 10L90 transmission is a 10-speed longitudinal automatic transmission that was designed to operate near the efficiency of a CVT while improving fuel economy in GM high-horsepower vehicles highlighted by the Camaro, Suburban, Tahoe, and Escalade. The 10L90 was a joint engineering effort between GM and Ford. Although the Ford 10R80 and GM 10L90 are very similar there are some differences in software and clutch specifications. The 10L90 transmission makes use of a triple-clutch assembly to allow it to fit two more gears while beings similar in size and weight to its 8L90 predecessor.

The 10L90 transmission is being tested on drag strips near you. Stock clutch failure looks to be a common occurrence for racers looking to break the 9 second quarter mile barrier.  Raybestos Powertrain is proud to have been first to market in 2019 with the first set of 10R80, 10L80, and 10L90 performance clutches. GPZ friction clutches have proven to handle increased horsepower and have helped produce dozens of under 9 second quarter mile track times in the similar Ford 10R80. We look forward to the future of 10L90 transmissions on the drag strip as we continue to develop new products for even faster track times.
