Are you swapping a 48RE into your 68RFE equipped 6.7L Cummins? Install this Full Send Diesel 48RE Swap line kit and ensure your transmission has adequate fluid flow. This kit includes all of the fittings you need to plumb a 48RE into your factory transmission cooling system. Built from the best braided hose and AN fittings the market has to offer. As always, this kit is backed by Full Send Diesel's lifetime workmanship warranty.

This line kit does not replace your factory lines, it simply connects to your new transmission and then you must cut the factory hardlines and plumb these braided lines in using the supplied compression fittings. This kit can bypass the transmission cooler thermostat, or be connected in before the thermostat to retain it.
