The 6L80 transmission is a 6-speed GM automatic transmission designed for rear-wheel drive, all-wheel drive, and four-wheel drive cars, trucks, and SUVs. The 6L80 transmission is found in Escalades, Silverados, Suburbans, Tahoes, and even in the high performance Corvette and Camaro. The 6L80 transmission provides optimum 6-speed performance and efficiency by taking advantage of a wide gear ratio and clutch to clutch operation. The 6L80 is slightly smaller than its 6L90 contemporary and features one less clutch plate in each pack than the 6L90. Raybestos Powertrain has developed a 3-5 Reverse redesigned ZPak (RZP-005) clutch pack and 4-5-6 redesigned ZPak (RZP-006) clutch pack to combat the common 3-5 Reverse and 4-5-6 clutch 6L80 transmission failure points.
