66RFE 68RFE TransTec Overhaul Kit 2007-2018 Ram 2500 3500

This is the TransTec (Freudenberg-NOK) overhaul kit for the Chrysler 66RFE and 68RFE six-speed automatics, the transmissions behind the 6.7L Cummins and 5.7L HEMI in 2007-2018 Ram 2500 and 3500 trucks. It is the paper-and-rubber side of a rebuild: every metal-clad seal, lip seal, molded piston seal, O-ring, sealing ring and gasket the case needs to go back together and hold pressure, plus the Duraprene molded pan gasket that replaces the throwaway cork or RTV bead.

TransTec is the OE-grade sealing brand most builders reach for because the seals are cut to the same spec the factory used, so clutch and servo apply pressures come back where they belong and you are not chasing a slow leak or a soft shift after the job. Use it with your own frictions and steels on a clutch-only refresh, or as the seal package inside a full master rebuild.

Fits 2007-2010 Ram 2500 and 3500, 2011-2019 Ram 2500, 2012 Ram 1500, and 66RFE/68RFE applications through 2018. TransTec kit number 81000518, also cross-referenced as DP2544. Does not include frictions, steels, bushings, filter, torque converter or fluid.
