6L80-E Automatic Trans with 45% More Torque Than the Production Version

Chevrolet Performance 6L80-E SuperMatic Six-Speed Automatic Transmission is based on the production version six-speed transmission found in many modern rear-wheel-drive Chevrolet cars and trucks. This aftermarket version of the transmission is enhanced with upgraded internal components that allow for a much higher torque output of 650 ft.lbs. Equipped with a 4.02:1 first gear for strong off-the-line acceleration and a 0.67:1 final gear for smooth highway cruising, the 6L80-E is perfect for any project vehicle running a Chevrolet LS engine in a RWD configuration.
