Keep your Allison transmission running cooler under the toughest conditions with the Banks Ram-Air Transmission Pan for 2020-Current Chevrolet Silverado HD and GMC Sierra HD models equipped with the Allison 10L1000 10-speed automatic transmission.

Using Banks' patented Ram-Air® technology, this innovative transmission pan forces cool air through integrated FlowThru Fins® to maximise heat rejection. Combined with an additional 3 quarts of transmission fluid capacity, it helps lower operating temperatures, extend transmission fluid life and improve reliability when towing, hauling or working your truck hard.

Manufactured from heavy-duty A380 die-cast aluminium, the pan features a breakaway Ram-Air scoop to protect against impact damage, internal cooling fins, a magnetic drain plug and a design that allows virtually complete fluid drainage during servicing. Despite its increased capacity, it maintains excellent ground clearance, making it an ideal upgrade for towing, commercial and off-road applications.
