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.

PPE’s Heavy-Duty DEEP Transmission Pans hold an extra 4 quarts of fluid and are cast from high-quality aluminum for optimal heat dissipation. Large 3/4 inch cooling fins outside and heat sink fins inside reduce operating temperatures up to 40 degrees.

The PPE Heavy-Duty DEEP Aluminum Transmission Pan also features a high-powered Neodymium-magnet-equipped drain plug to keep metal contaminants out of the transmission internals.

PPE exclusive built-in filter lock comes standard and keeps deep filters securely in place. Allen-head mounting bolts and a new deep filter are included with this kit. Must use original style Allison pan gasket.
