aFe 22-24 Toyota Tundra BladeRunner Transmission Oil Cooler Kit

The transmission is the backbone of your RAM. It’s responsible for transmitting large amounts of torque from your 6.7L Cummins powerplant, and that torque generates heat. If that heat isn’t dissipated, it can destroy your transmission. The transmission cooler does a good job of keeping trans fluid temperatures in check, but only if the fluid can reach it. The stock cooling system of both the 68-RFE and Aisin AS69RC utilize an in-line thermal bypass valve that controls the flow of fluid to the transmission cooler. The purpose of this valve is to prevent transmission fluid from flowing to the cooler until it reaches operating temperature. The thermostat inside this valve is prone to failure, however, and when that happens, the fluid never flows to the cooler and the transmission can overheat. That’s why Mishimoto has developed an improved thermal bypass valve kit for your 2019+ Dodge Ram 6.7L Cummins. Our CNC-machined aluminum thermal bypass valve not only looks better than the stock unit, but it performs better too. The Mishimoto thermal bypass valve utilizes a replaceable thermostat that is more durable than the stock thermostat and opens about 10 F earlier. This allows fluid to flow to the cooler sooner, without over-cooling. For owners in hot climates, the Mishimoto valve includes a bypass that allows full flow to the transmission cooler, regardless of temperature. The bypass can be easily swapped out with only a wrench for summer or winter driving. The Mishimoto thermal bypass valve flows better in both configurations than the stock valve for more effective cooling. Cooling fins machined into the valve body add even more heat dissipation. This 2019+ Dodge Ram 6.7L Cummins Thermal Bypass Valve Kit is built to last a lifetime with a durable black anodized finish and our Mishimoto Lifetime Guarantee.
High-performance component designed to enhance thermal efficiency, durability, and reliability under demanding conditions. Engineered to support optimal temperature control and system performance across applications.

CSF is the world leader in cooling technology. From its experience starting with the transmission in the BMW F8X M3, M4, and M2 Comp, CSF applied several different features exclusive to its manufacturing technologies. An innovative dual-core design allows for a 240% increase in core volume, resulting in maximum performance and maintaining optimal shifting during extreme racing conditions – from road racing to the drag strip. During R&D, CSF consulted with a network of partners, including leading time attack teams, tuners, and more. Often, the feedback was gearbox fatigue and sluggish shifting with transmission temperatures overheating under prolonged or hard use. CSF has the answer with our industry-leading transmission cooler for the A90/91 Supra and BMW G-Series. Installed in one of the world’s fastest A90 Supra – Titan Motorsports Drag Race Supra (first Supra to reach 8s in the 1/4 mile).
CSF offers the best and most advanced Transmission Coolers on the market. Keeping your transmission temps down as you push your Supra / BMW hard on the street or track.
The CSF #8183 Cooling product is designed to be a “Drop-In Fit” application.
