6L90 Transmission

The 6L90 transmission is a 6-speed GM automatic transmission designed for rear-wheel drive and rear focused all-wheel drive vehicles. Paired with GM's V8 Vortec VVT and V8 Duramax engines the 6L90 transmission is found in GM heavy duty and diesel trucks, cargo vans, and the Camaro ZL1. The 6L90 transmission provides optimum 6-speed performance and efficiency by taking advantage of a wider gear ratio instead of traditional planetary gearset design. The 6L90 is larger than its 6L80 contemporary and features one more 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 6L90 transmission failure points. See more product details below.
