Derale GM 4L80 & 4L80E Transmission Cooling Pan

Derale's Transmission Cooling Pan #14207 uses air passing beneath the vehicle and redirects it to help lower transmission oil temperatures. Designed for GM's heavy duty 4L80E transmissions, this pan features brazed, turbulator-equipped airway tubes passing through the lower section of the transmission pan for more efficient cooling, each is individually pressure tested to ensure a leak-free pan. We've included a much stronger magnetic drain plug and rubber/steel reusable washer, in addition to a 1/8" NPT temperature sender bung located in the side of the pan. Finished with a durable black two-stage coating, each pan also includes neoprene gasket and 1/8" NPT temperature sender plug.
