SuperMatic™ 8L90-E 8-Speed Automatic Transmission for LT1 Crate Engine

When it comes to world-class performance and technology, the Corvette and Camaro run with the best. Their advanced Gen V LT1 engines are among the most power-dense in the industry and they’re offered with equally sophisticated transmission technology in the 8L90-E eight-speed automatic.

Best of all, unique algorithms enable the 8L90-E to deliver shift performance that rivals the quickest dual-clutch/semiautomatic transmissions found in many supercars – but with the smoothness and refinement that comes with a conventional automatic fitted with a torque converter.

A numerically high 4.56 first gear ratio offers strong take-off performance while a wide 7.0:1 overall ratio helps enhance cruising efficiency. This version incorporates a slip yoke design (to be used with the LT1) and includes the torque converter, controller and harness.
