Keep your Allison transmission running cooler with the Banks Ram-Air Transmission Pan for 2001-2019 Chevrolet Silverado HD and GMC Sierra HD 2500/3500 models equipped with the Allison 1000 automatic transmission.

Using Banks' patented Ram-Air® technology, this heavy-duty transmission pan forces cooling air through the integrated FlowThru Fins® to remove heat more efficiently than the factory pan. Combined with an additional 2 quarts of transmission fluid capacity, it helps reduce operating temperatures, extend transmission fluid life and improve durability when towing, hauling or working your truck hard.

Manufactured from precision die-cast A380 aluminium, the pan features a breakaway Ram-Air scoop to protect against impact damage, a magnetic drain plug for easier servicing and a design that allows complete fluid drainage during maintenance. With significantly greater heat rejection than the factory transmission pan, it's an ideal upgrade for heavy-duty Duramax owners.
