About the 4L80E Transmission

GM designed the 4L80E as an electronically controlled successor to the TH400, adding an overdrive gear while keeping much of the TH400’s legendary strength. It was used in 2500 and 3500 trucks, Suburbans and vans for nearly two decades. Its ability to handle high torque makes the 4L80E transmission a favourite for turbo LS builds, drag cars and tow rigs.
