Chevrolet Performance has adapted the production-based 8L90-E 8-speed automatic transmission for use with the LT4 crate engine. 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. Two versions are available: a slip-yoke design for use with the LT4 engine, or a fixed-yoke design for use with the LT1 engine.
Connect & Cruise Crate Powertrain Systems provide factory-matched engine-and-transmission combinations that include specially calibrated controllers and wire harnesses designed for retrofit installations in older vehicles. Connect and Cruise packages are available for a wide variety of crate engines which can be paired with an automatic or manual transmission.
