    PML designed this stock capacity transmission pan for the GM TH350 (Turbo–Hydramatic 350) transmission.

    Benefits:

    • Drain hole and magnetic drain plug for easy fluid changes
    • Finned for cooling
    • Heavy duty sand cast aluminum construction
    • 1/2 inch deeper than stock for vehicles with little ground clearance or skid plates
    • Machined flat gasket sealing surface
    • Can optionally be machined for a temperture sending unit

    PML also makes an extra capacity version of this pan. The extra capacity TH350 pan, PML part number 9684, does not have external bosses that may interfere with the drive shaft on some vehicles.

    TheTH350 transmission was first available in 1969 after joint development by Buick and Chevrolet. It continued in production in the 1980s. The TH350 transmission is called Turbo 350 in the racing field and is formally called THM350 for Turbo–Hydra–matic 350.

    The TH350 transmission is found in GM (Chevy, Cadillac, Olds, Buick) vehicles as well as retrofitted Jeeps and other cars and trucks. For example, this transmission was originally on 1967 to 1972 El Caminos, Blazers, and C/K 20 trucks and Suburbans.

    Always check your vehicle to verify transmission and clearance. This PML pan will fit the Turbo 350 transmission, but it is larger than stock. Make sure to check for clearance with the drive shaft and bosses on the passenger side of the pan.
