This PML pan fits cars and trucks with the GM TH350 (Turbo-Hydramatic 350) transmission. The transmission was first available in 1969 after joint development by Buick and Chevrolet. 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.

The pan has a boss that can be machined for a temperature sensor.

The TH350 transmission is called Turbo 350 in the racing field and is formally called THM350 for Turbo-Hydramatic 350. It first appeared in cars in 1969 and continued in production in the 1980s.

PML moved the drain plug and optional temperature sending bosses in 2014. These interfered with the drive shaft on some vehicles.

PML also offers a low profile version of this pan for vehicles that need more ground clearance. The low profile pan, PML part number 9589 has the external bosses that may interfere with the drive shaft on some vehicles.

The filter bolts on to the valve body so no filter supports or extensions are needed.
