Description

Banks brings Ram-Air cooling to the Allison 1000 transmission. Using technology from our patented differential covers, the Banks Ram-Air Transmission Pan extends fluid oil life by rejecting more heat than stock and all competitors. An additional two quarts of capacity, a break-away Ram-Air scoop, and Banks FlowThru Fins aid in cooling. Cooler fluid means a longer-lasting transmission.

Engineered To Run Cool

The Banks Ram Air Transmission Pan for 2001-2019 Duramax trucks with Allison 1000 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 designed to break away without causing damage to your pan. Just let us know, and we will send a replacement Ram-Air scoop on the house.

Banks Ram-Air Transmission Pan Technical Features

A 1/8" NPT port for easily adding a supplemental temperature sensor.

24 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.

18 internal fins absorb more heat from the oil than a standard or all aftermarket pans.

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

The Banks proprietary FlowThru FinsTM 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 Stock

When comparing aginst the stock L5P configuration there are two options, the Standard Pan and an optional Deep Pan which offers about 3 quarts of extra fluid capacity

While the additional fluid capacity does help in lowering temperatures initially, without aditional means to cool the fluid, it quickly becomes heat soaked with no means to rediate the aditional heat load.

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 FinsTM 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.
