Description
The TSI 700HP Stage 2, 4L80E High-Performance Transmission is the ideal solution for your hot rod, LS swap, or custom build where you need reliable overdrive, torque converter lock-up and solid power handling. Built to withstand up to 700 horsepower, this transmission is fully rebuilt using premium components and includes upgraded internal components like performance clutches, an enhanced sprag, TCC Regulator valve, and our version of the shift kit for firm, clean shifts under load.
Designed for street and mild strip use, this unit is perfect for improved holding power and drivability. Pair it with a TSI Single or Triple Disc lockup torque converter for maximum efficiency—lockup reduces heat, improves fuel economy, and drops cruising RPM.
