Mishimoto MMTC-WRX-15 19-Row CVT Transmission Cooler Kit for 2015-2021 Subaru WRX

Fits 2015-2021 Subaru WRX Base, Limited, and Premium models equipped with a CVT.

Protect your continuously variable transmission from the damaging effects of overheating. While the CVT in the 2015-2021 Subaru WRX provides smooth, seamless gear changes, high-stress conditions like track driving, towing, or steep grades can cause fluid temperatures to climb, potentially leading to premature component failure. The Mishimoto MMTC-WRX-15 cooler kit is a robust thermal management solution designed to keep your transmission operating within safe temperature ranges.

This kit features a large 19-row stacked-plate oil cooler mounted at the front of the vehicle to utilize maximum airflow. Mishimoto engineers designed this system to work in series with the factory transmission cooler, creating a dual-cooler setup capable of handling extreme loads. During rigorous testing—including full-occupant uphill climbs—this kit demonstrated a consistent 20°F (6.7°C) drop in transmission fluid temperatures. The direct-fit design ensures a clean installation with no cutting or vehicle modification required.
