Overview

Pro Series Front Differential Cover (46-71051B) by aFe. Upgrade your transmission with this finned aluminum pan and increase fluid capacity, improve fluid cooling and ease future maintenance jobs. It includes a magnetic drain plug, temperature sensor port, and internal and external cooling fins. With its reinforced ribs and wrinkle black powder coated finish, it's both strong and stylish.

Replace your stock, stamped steel transmission pan with this deep, finned aluminum pan and extend the life of your transmission. Transmissions that run cooler last longer, and the increased fluid capacity and internal and external cooling fins on this cast aluminum pan will reduce transmission fluid temperature. And even though fluid capacity is increased by 3 to 4 quarts, no modification to the dipstick is needed.

This transmission pan is made of rugged die-cast A380 aluminum. The cooling fins are cast in along with reinforced ribs for strength. It includes a 1/8" NPT port for the temperature sensor, and a magnetic drain plug to catch loose particles and help protect the transmission. The drain plug will also make fluid changes easier; say goodbye to loosening screws and tilting the pan to drain the fluid! A durable, wrinkle black powder coated finish is applied to the pan to preserve its appearance.

Everything necessary for installation is included in the kit except for the pan gasket, spin-on filter and pickup screen.
