Despite its name, the 4L80E is not an upgrade to its GM counterparts. Introduced alongside the original 4L60 in the early 90’s the 4L80E was designed for large trucks and is designed as a heavy duty unit, rather than a transmission for smaller cars or even some pickups. Applications that use this transmission include the 8.1 L Avalanche, the Tahoe, and the Hummer. Monster provides a wide selection of different performance ratings in our transmissions, including mild, heavy duty, super sport, and SS Xtreme.
