# Mishimoto 10-12 Ram 2500/3500 6.7L Cummins Transmission Cooler - Bypass

Upgrade your 2010-2012 Dodge Ram 2500/3500 6.7L Cummins with the Mishimoto Transmission Cooler Bypass Kit. Designed for a direct fit, this line kit allows a customer to leave their factory transmission cooler in place, negating the need to discharge the refrigerant in the A/C system, but bypasses the factory transmission cooler in the event it is contaminated from a transmission failure. You don't need to worry about dealing with freon or vacuum lines, so you can get back on the road quickly. This kit is made to be used with the MMTC-RAM-10 Transmission Cooler, ensuring compatibility and ease of use. Plus, it comes with the Mishimoto lifetime warranty, giving you peace of mind and reliable performance.

-   This kit is meant to be used with our MMTC-RAM-10 Transmission Cooler
-   Bypasses the stock transmission cooler and A/C condenser
-   Hassle-free installation
