GM 10-Speed Automatic Transmission

P/N 19420480

The SuperMatic 10L90-E 10-speed automatic transmission offers a technologically advanced balance of performance and efficiency when matched with Chevrolet Performance”s LT Crate Engines, including the LT4, and LT5. Based on the robust transmission offered in the Camaro SS ZL1, as well as the latest full-size trucks and SUVs, our SuperMatic 10L90-E transmission kit features a slip yoke-type tail shaft, allowing it to be used with the conventional prop shaft design used in most older vehicles. That makes it easier to install on LT engine swaps into vintage cars, trucks, and SUVs.

The 10L90 is one of General Motors” most advanced automatic transmissions, and its wider 7.39 overall gear ratio spread enhances off-the-line performance, with an aggressive first-gear ratio of 4.70. Three overdrive gears in the 10-speed enable lower-rpm highway driving that can enhance fuel economy, allowing your resto-mod or Pro Touring classic to deliver a great balance of performance and efficiency. Our 10L90-E includes the torque converter and controller.
