Fitment

General Motors vehicles equipped with the 6L80 6-speed automatic transmission (e.g., 2010-2015 Camaro, and 2007-2013 GM 1500 Trucks & SUVs)
Truck owners must verify they have a 6-speed 6L80 and not a 4-speed transmission as 07-13 both were available
Ideal for high-horsepower builds, including positive displacement superchargers, turbo setups, and heavy nitrous applications

Note: Transmission tuning is highly recommended when upgrading to an aftermarket torque converter. Verify compatibility with your specific 6L80 application before ordering.
