Banks Power Ram-Air Transmission Pan Black Powder Coat - 2001-2019 Chevy/GMC 2500/3500 6.6L Diesel with 5 or 6 speed Allison 1000 Transmission - 35146-B

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 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. Patent Pending

Why It's Better
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 Pans' Patent Pending design draws ambient air through the large forward-facing scoop, funneling it through the external heat radiation fins.

Unlike competitive designs where the metal of the pan hangs the lowest, the Ram-Air Transmission Pan is engineered so that the lowest point is only the sacrificial front scoop while still providing 2 additional quarts of fluid capacity.

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.
•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.
•Die-cast process provides a smoother, less porous interior surface and improves fluid flow in the pan.
The Banks proprietary FlowThru Fins™ 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
The stock Duramax pan is made from stamped steel which has no internal or external fins to assist in removing heat from the fluid inside.
Without additional means to cool the fluid, it quickly becomes heat soaked with no way to radiate the additional heat load.


Die-Cast vs Sand-Cast
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 often retain the sand they were molded with. Sand is an abrasive material that is bad for bearings and cylinder walls. In other words, 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, it's worth it.
Fluid Dynamics
Internal cooling fins run inline with the drain port with streamlined passageways
Downward-facing port eases oil change process
Lower aeration means longer fluid life
