Derale's Transmission Cooling Pans use the air passing beneath your vehicle to help lower transmission oil temperatures. These pans feature brazed, turbulator-equipped airway tubes passing through the lower section of the transmission pan for more efficient cooling. Each piece is individually pressure tested to ensure a leak-free pan. Most factory filters and pickup tubes can also be utilized. Each pan is finished with a durable black two-stage coating, and also include a neoprene gasket and 1/8" NPT temperature sender plug.
