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.

Installations

• 2019 Yukon Denali

2019 Sierra 1500

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.
