PPE's Heavy-Duty Deep 10L80 Transmission Pan holds an extra 4 quarts of fluid and is cast from high-quality aluminum alloy for strength and optimal heat dissipation. Simply stated, more is always better when it comes to transmission fluid. Higher volumes of fluid take longer to heat up allowing for more stable transmission temperatures which help to extend transmission life. Cast gussets provide strength and overall robustness. Internal heat sinks wick heat and acts as baffles to reduce fluid sloshing. External fins add surface area and use free-flowing air to radiate heat. The PPE Heavy-Duty Deep Aluminum Transmission Pan also features a high-power Neodymium magnet-equipped billet stainless steel drain plug to catch and hold harmful ferrous metal contaminants keeping them out of the transmission internals.
