Ram-Air Transmission Pan

Engineered To Run Cool

The Banks Ram Air Transmission Pan for 2020-2024 Duramax trucks with the 10-speed 10L10000 transmission outperforms and outcools the competition by leveraging decades of Ram-Air technology and thermal management expertise honed in racing and military engine development.

Taking advantage of the fast-moving cool air under your truck, the Ram-Air Transmission Pan draws ambient air through the large forward-facing scoop, funneling it through the external heat radiation fins.

The plastic scoop is also designed to break away without causing damage to your pan, just in case. If this happens to you, let us know and we will send a replacement Ram-Air scoop on the house.

•1/8" NPT port for easily adding a supplemental temperature sensor to your vehicle.

•22 deep-cut external radiator fins provide more exposed surface area to the cool air moving under the truck.

•Integrated support structure for internal filter acts as anti-slosh baffles for fluid in the pan.

•20 internal fins absorb more heat from the oil than a standard pan or all other aftermarket pans.

•Die-cast process provides a smoother, less porous interior surface and improves fluid flow in the pan.

The Banks proprietary FlowThru Fins^TM maximize thermal energy transfer by lining up the internal absorption and external radiator elements with each other.

Transmission fluid heat is efficiently drawn from the fluid, reducing stress on your Duramax's cooling and lubrication systems.

Banks vs The Competition

What happens when the Ram-Air goes against the competition? While others claim to have massive cooling ability with their designs featuring fins that cross haphazardly across their surface with no concideration for fluid dynamics, the Banks Ram-Air still comes out on top in total internal and external fin area.

What all others lack though, is the forward facing Ram-Air scoop to help guide the air under your truck directly through its die-cast FlowThru Fins^TM which further enhances heat transfer out of your fluid and away from your transmisison. No ohter pan is as well engineered.

Die-Cast vs Sandcast

All Banks lubrication cooling products are die-cast, not sand-cast like competitors. Made with far greater precision, a die-cast part is denser, smoother, and has virtually no porosity compared to the equivalent sand-cast part.

Sand-cast parts can even retain the sand they were molded with. (You don’t want sand in your oil). Finally, our long, thin cooling fins are only possible with a die-cast process. Although this process costs more, we think it's worth it.
