Product Description
When installed, the Mishimoto engineers put the transmission cooler through a series of rigorous tests, including driving the vehicle, fully-loaded with occupants and supplier, up a steep grade to measure the efficiency of the 19-row oil cooler. Mishimoto engineers saw consistent 20°F (6.7°C) drops in transmission fluid temperatures, with temperature decreases even during normal driving. If you drive your CVT WRX hard on the racetrack or street, the Mishimoto CVT Transmission cooler is a must!
Mishimoto engineers thought of everything for your 2015-2021 WRX with this simple and easy-to-install kit. The application-specific mounting brackets feature mounting holes for popular aftermarket horns. The rubber lines are pre-cut to length and fit with your stock transmission fittings. All of the necessary hardware and clamps are supplied, making this installation simple. The oil cooler is available in either Sleek Silver or Stealth Black to suit your taste. As with all of our 2015-2021 WRX parts, this kit includes the Mishimoto Lifetime Warranty.

Mishimoto Subaru WRX CVT Transmission Cooler
For our third prototype unit for the CVT cooler, we decided to take a more traditional approach. We would place the cooler in a location that would guarantee airflow. The main concern was fitting our large 19-row cooler in a position that would not leave any space for other aftermarket components. First, we mocked-up the cooler and developed some basic brackets that would place the cooler in an angled position behind the upper grille area. Check out a few shots of the mounted cooler!

After we witnessed reasonable performance gains with our first prototype, we decided to evaluate what we liked and didn't like with the design.
Pros
- Short line lengths
- Efficient cooling
- Compact design and packaging
Cons
- Did not achieve the temperature decreases we wanted to see
- Requires wiring of the electric fan
- Airflow was not as sufficient as it could be
This first design was efficient but not ideal for what we wanted out of the project. To obtain the desired cooling benefits, the addition of an electric fan was necessary. However, the fan would add complexity and wiring to the product, which we would like to avoid. So we hit the drawing

Welcome back! The quest for low transmission fluid temperatures continues. Once we developed our goals and plan of action for this project, our engineering team went to work, grinding, welding, bending, and cutting. Our first prototype design was quite unique. We mounted one of our 19-row, stacked-plate fluid coolers next to the liquid-to-liquid transfer unit. This is the same location as the turbocharger on the previous generation of EJ engines. Check out the beginning of the mock-up below!

The lines are rubber with a sheathing to protect them from any rubbing. This unit mounts to the side of the engine block on the passenger side. After evaluating the stock unit, our team decided to design a product to assist the stock unit. The stock setup also functions as a fluid warmer, which will help bring the fluid up to operating temperature, and then our supplemental cooler will help retain optimal temperatures. Check out our test vehicle below!
