Mishimoto MMTC-U Universal Transmission and Power Steering Cooler Kit 3/8"

Vehicle Fitment

• Universal - compatible with automatic transmission vehicles requiring a standalone external fluid cooler; also suitable as a power steering cooler or supplemental engine oil cooler
• Commonly paired with Mishimoto radiators that are rated for manual transmission only, enabling automatic transmission use

Fitment Notes

Product Description

The Mishimoto MMTC-U is a universal automatic transmission and power steering cooler kit designed to provide external fluid cooling across a wide range of vehicles and applications. Many Mishimoto aluminum radiators are engineered for manual-transmission vehicles only and do not include an integrated transmission cooler - the MMTC-U is the recommended companion that makes these radiators compatible with automatic transmission applications by handling transmission fluid cooling externally. It also serves as a standalone supplemental transmission cooler for trucks, SUVs, and tow rigs where the factory cooler is insufficient under sustained heavy load.

The two-row aluminum tube-and-fin core measures 15.5" x 5" x 0.75" and uses standard 3/8" push-on fittings, which are compatible with most automatic transmission cooler lines - verify your vehicle's line diameter and consult your service manual before installation. In addition to ATF, the MMTC-U is compatible with power steering fluid, engine oil, and other automotive fluids, making it a versatile standalone cooler for various applications. Note that custom work or adaptation may be required for certain installations and professional installation is recommended. All necessary mounting hardware is included. Backed by the Mishimoto Lifetime Warranty.
