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!
