Heat is what takes transmission fluid out of the fight. Tow heavy, run in hot weather, or pull long grades, and the transmission and converter can spend too much time at the edge. The Banks Ram-Air Transmission Pan attacks that problem before fluid temperature gets out of hand. We use a forward-facing Ram-Air Scoop to capture air under the truck, compress it, and drive it across the pan’s Flow-Thru Fins®. Those fins connect the inside of the pan to the outside, so heat has a direct path out of the fluid and into the airstream. That’s the difference: not just more finning, but forced-air cooling working with aligned internal and external fins. The die-cast aluminum construction matters too. It gives us a dense, precise casting with smooth internal surfaces and thinner walls, which helps heat move out faster. We also built in serviceability with a magnetic drain plug at the lowest point for a more complete drain, and the scoop is a breakaway design that can be removed with four bolts if needed. Bottom line: better heat rejection, better fluid life, and less transmission stress when the truck is working hard.
The video opens with the premise that transmission durability is increasingly tied to temperature control. Trucks that tow heavy loads, operate in hot climates, or spend time on long grades can push both the transmission and torque converter toward excessive heat. Banks presents its new Ram-Air Transmission Pan as a tool intended to reduce those temperatures before they become a problem, framing it as a durability-focused component rather than a cosmetic accessory.
Banks explains that the pan lowers temperature by using airflow already moving under the truck. Instead of relying only on passive finning, the design captures cooler air and forces it across the pan's external cooling surfaces. The company attributes the pan's performance to three linked elements: the die-cast construction, the fin design, and the Ram-Air feature itself. According to the video, competing pans do not incorporate this Ram-Air approach.
At the front of the pan is a Ram-Air scoop designed to capture, compress, and accelerate incoming air. Banks says this concept builds on what it learned while developing its patented Ram-Air differential covers. The scoop is intended to direct airflow over the pan in a controlled way so that the cooling surfaces see more effective air movement than they would from incidental underbody flow alone.
The pan uses what Banks calls Flow-Thru Fins®. Viewed head-on, the fins run from front to back, and the video emphasizes that they connect the inside of the pan directly to the outside. That creates a direct heat path from the transmission fluid to the external airflow. Banks argues that this internal-to-external fin continuity is central to the design and says it is not practical to match this combination of internal and external fin surface area without using high-pressure die casting.
Banks describes the pan as a high-pressure die-cast aluminum part. In its explanation, aluminum is heated to 1,300 degrees and injected into a preheated H13 tool steel mold at 5,500 lb per square inch. The process happens essentially instantaneously. The company presents this as the correct way to cast lubrication-related products because it produces a precision casting with no porosity. The resulting surface finish is described as extremely smooth, which Banks says benefits fluid flow. The walls are also thinner and very dense, which improves heat transfer and thermal recovery. In practical terms, the claim is that thinner, denser walls let heat leave the fluid more quickly.
Banks also addresses practical use conditions. For owners concerned about winter operation, the Ram-Air scoop can be removed by taking out four bolts. The scoop is also designed to break away if it strikes an obstacle, without damaging the transmission pan itself. The video adds that if such a breakaway occurs, Gale says he will send a replacement scoop at no charge.
Beyond cooling, the pan includes a serviceability improvement. Banks says the Ram-Air Transmission Pan provides a more complete drain without requiring removal of the pan because it places a magnetic drain plug at the very lowest point. That location is intended to improve fluid draining while also giving the plug the ability to collect metallic debris.
The pan is said to be available for several transmissions: the Allison 5-speed and 6-speed, the newer Allison 10-speed, and the Mopar Ram 68RFE. Banks concludes that its original goal was simply to lower transmission fluid temperatures, but the company now characterizes the result as a major redesign of the transmission pan itself, centered on airflow management, die-cast construction, and direct heat-path finning.
