Mishimoto Ram 2500/3500 2010-2013 6.7L Cummins Transmission Cooler Bypass Line Kit

The Mishimoto transmission cooler bypass line kit for the 2010-2013 Ram 2500/3500 6.7L Cummins is a direct-fit line set designed to be used with the MMTC-RAM-10 transmission cooler. It bypasses the factory transmission cooler — important after a transmission failure, where the OEM cooler can be contaminated — while leaving the factory cooler physically in place, so there's no need to discharge the A/C refrigerant or deal with vacuum lines. Hassle-free installation gets you back on the road quickly.
