TRANSMISSIONS | CHEVY | 4L80E

Despite its name, the 4L80E is not an upgrade to its GM counterparts. Introduced alongside the original 4L60 in the early 1990s, the 4L80E is 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 various performance ratings in our transmissions, including our StreetMonster (100 HP over stock) and the SportMonster (600 HP).
