    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.

    Fluid Level Check

    The transmission fluid level check is in the pan. The level check is at different heights depending on the stock pan.
