4L80E Rebuilt Transmission

The 4L80E transmission is a 4-speed automatic transmission developed by General Motors, introduced in 1991 as a heavy-duty upgrade to the 4L60E. Based on the Turbo-Hydramatic 400 (TH400), a legendary 3-speed transmission known for its strength and reliability, the 4L80E added an overdrive gear and electronic controls, making it a modern solution for high-torque applications. It was designed to handle the demands of large trucks, SUVs, vans, and performance vehicles, becoming a staple in GM's lineup for decades.

The 4L80E was engineered for vehicles requiring greater torque capacity and durability. Its robust design includes a reinforced aluminum case, heavy-duty gearsets, and a lock-up torque converter for improved fuel efficiency during highway driving. The addition of electronic controls allowed the transmission to adjust shift points and line pressure based on engine input, ensuring smooth performance under varying conditions. The 4L80E was commonly paired with big-block V8 engines, diesel engines, and even high-performance applications, such as the Hummer H1 and Chevrolet Suburban 2500.
