Mixing coolant into your transmission fluid can have catastrophic results, and can cost thousands of dollars in rebuilding or replacing the transmission. The Mishimoto Replacement Transmission Oil Cooler is a direct fit to the OEM, making it easy-to- install and is equivalent to the OEM Specifications of performance. This product requires no modifications and is backed by Mishshmoto’s Lifetime warranty. Replace your transmission cooler and prevent premature failure.
