    PML Design and Benefits

    PML is looking into the design and development of an extra capacity, heavy duty pan for the GM 8L90 transmission. Our design includes these benefits:

    • Extra capacity
    • Finned
    • Drain hole and magnetic drain plug
    • Work with stock filter
    • Heavy duty sand cast aluminum construction

    We are collecting information about vehicles, fitment, and applications. Please sign up for our email list if you are interested in a 8L90 transmission pan.

    We welcome pictures, measurements, and suggestions. Please email us pictures of your stock pan on your truck, SUV, or care with any info to: yourcovers@pmli.com

    If there is enough interest, we would start this project in 2021.

    Applications

    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.
