About the 6L80 Transmission

Introduced in 2006, the 6L80 is a popular, 6-speed, RWD transmission produced for more than 8 million trucks, SUVs and cars. It's used by GM in about 20 models, most widely in the Chevy Silverado, Tahoe and Suburban, the GMC Sierra and Yukon, and the Cadillac Escalade. The 6L80 also is found in the Chevy Corvette and GMC Hummer. A heavy-duty version of the 6L80 — the 6L90— was introduced in 2007 for select GM trucks and vans.
