Benefits of PML Design

Extra capacity
Finned to increase surface area for heat dissipation
Drain and magnetic drain plug
Thick walls and gasket flange
Heavy duty construction
Compatibility with OEM vehicles with the fluid level check in the OEM pan

PML designed this transmission pan with many benefits while keeping in mind clearance issues such as exhaust cross over pipes.

The PML pan can replace stock pans with or without the fluid level check on the OEM transmission pan.

May also fit GM 10L60 transmissions.

Status

In 2024, we made some prototype pan for GEN1 transmissions. We have a few of these available. After updating the design, we are making more prototype pans. Prototype testing to begin June 2025. If you are interested in PML's prototype program, email us at [email protected]

2020 and newer Silverado 1500
2020 and newer Sierra 1500

Always check your vehicle configuration before ordering! Models vary. Transmissions other than the 10L80 are possible. This PML pan is larger than stock so check clearances.

Although Ford and GM jointly developed this 10 speed transmission, GM 10 speed 10L80 transmissions began appearing in 2020 models and Ford 10 speed 10R80 transmissions began appearing in 2017 models. The transmission pans are not interchangeable.

Our thanks to Paul for installing this PML pan and providing his feedback and many pictures. Paul reported that the PML pan was a 100 percent match and installed with no clearance issues whatsoever.

Paul installed this pan in his driveway/garage and took 3 to 4 hours. His truck has true dual exhaust so he loosened one side of the exhaust from the header flange to drop the pipe 2-3 inches. A lisiting of the tools he used is below the pictures.
