Since there are two different stock pans, we are looking at a design that could replace both stock pans.
If you have a valve body, used and not functional ok, from a 2020 or new Sileverado/Sierra, let us know.
The GM 8L90 transmission can be found on 2015 and newer Chevrolet, Cadillac, and GMC vehicles.
- 2015 and newer Cadillac Escalade 6.2L
- 2015 and newer Chevrolet Silverado 6.2L
- 2015 and newer GMC Sierra 6.2L
- 2015 and newer GMC Yukon Denali/Denali XL 6.2L
- 2016 and newer Chevrolet Tahoe 6.2L
- 2017 and new Colorado and Canyon, gas engines (may be 8L45)
- Some 2015 and newer models of Camaro, Carpice, Corvette, and Cadillac cars also have the 8L90 but probably lack ground clearance for a deeper transmission pan.
Always check your vehicle to verify transmission and clearance. Configurations vary. Cars may not have enough ground clearance for a deep pan.
For 2017 gas engine Canyon and Colorado, GM switched to an 8 speed transmission from the 6 speed 6L50. See article in The Shop Magazine.
