Banks brings forced 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 No. US 12,313,156 B1
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' Patented design provides forced air cooling as it draws ambient air through the large forward-facing scoop and 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.
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.
What happens when the Ram-Air goes against the competition? Some brands also claim to have massive cooling ability with designs that feature exposed fins. But after closer inspection, these fin layouts appear to cross haphazardly across their surface or have blind corners that obstruct fluid flow and collect sediment.
Plus, what all others lack, is the forward-facing Ram-Air scoop to help guide the air under your truck directly through its die-cast FlowThru Fins®, which further enhances heat transfer out of your fluid and away from your transmission. No other pan is as well-engineered.
All Banks lubrication cooling products are die-cast, not sand-cast like some 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.

"Banks never lets me down. This was a great upgrade to my truck. I dont tow very often but I do have 35" tires and that put a little extra strain on the transmission. Adding this pan, I have clearly noticed that the transmission takes longer to get up to the standard 185 temp and generally runs cooler. I'm not surprised Banks nailed it again!"
"The appearance and finish is amazing and the installation went perfect I saw a 20% drop in temp on my first real heavy tow and it cooled down much quicker that the stock pan"
"The pan does exactly what it is supposed to do. I pull a trailer every time I use this truck and im always worried about over heating the transmission, this pan lowered my temperature by an average of 12 degrees. Thanks you for the great invention"
"Great fit on my 2015 LML. Hardware package was missing two bolts but I reached out to customer service and with no questions asked they sent out the missing hardware. I appreciated the gift they sent as well. Thanks."
"The Banks transmission pan is hands down one of the best upgrades I’ve added to my truck. The quality and craftsmanship are top-notch—you can tell right out of the box that Banks put a lot of thought and engineering into this product. Fitment was excellent, installation was straightforward, and once installed, it looks incredible underneath the truck. More importantly, it’s a functional upgrade, not just something that looks good. The added fluid capacity and improved cooling give me extra confidence in keeping transmission temperatures under control, especially with a modified truck that gets driven and shown regularly. I’m extremely happy with the overall quality, design, and attention to detail. If you’re looking to upgrade your transmission pan and want something that combines performance with a great-looking finished product, I definitely recommend Banks. ⭐⭐⭐⭐⭐ 5/5 — Quality product and a great addition to the build!"
"#1 Professionally Design To Work #2 Easy to install #3 Quality Made #4 Banks sends everything to complete the install. My transmission stays usually at 150 degrees. Best of all - o'ring instead of pan gasket and drain plug. Thanks"
"looks cool haven't had it on for a long drive on interstate to check for drop in temp around town no change."
"By adding this transmission pan, it lowered my transmission temperature at least 15° while towing."
"Got trans pan and diff cover. Love them both. Hurry up and make the oil pan for the 15 lml so I can get it."
"I love my trans pan, really works great . thank you"
