PML Transmission Pans and Differential Covers provide many benefits for off-road, towing, and racing applications. The covers and pans feature sand-cast aluminum construction and machined gasket flanges. The result is a finished part that actually increases the torsional strength of the transmission case or differential housing and a gasket surface that remains flat far better than stock parts. Magnetic drain plugs make oil changes easy. On deep or extra-capacity covers and pans, extra oil provides cooling for the transmission and differential under stressful conditions. Heat build-up causes oil to lose its lubricating properties which leads to increased wear on the clutches, bands, and seals. The end result is costly premature rebuilds and lost time. Our covers and pans feature raised cooling fins in addition to the increased fluid capacity to reduce oil temperatures. Customers have reported temperatures 20 to 30 degrees cooler.

PML Valve Covers feature stiff aluminum construction with thick walls and a machined gasket flanges to provide a uniform clamping force on the gasket, ensuring a secure seal far superior to thin stamped steel valve covers that are stock on most vehicles. PML offers many styles and finishes for a custom look under the hood.

PML also does private label parts for those customers interested in promoting their idea or company name on machined castings. Contact PML for a quote based on your requirements.
