AS68RC Transmission Master Rebuild Kit, Ram 2500 3500 Cummins

This is a complete friction, gasket, and seal overhaul kit for the Aisin AS68RC, the six-speed automatic that sits behind the 6.7L Cummins in 2007.5-and-up Ram trucks - the 3500, 4500 and 5500 cab-and-chassis and the heavier 2500/3500 applications that got the Aisin unit instead of the 68RFE. Open this kit when you are tearing an AS68RC down for slipping clutches, a burnt overdrive pack, or a fluid-and-metal teardown after a converter came apart.

The clutch pack is Raybestos AS68RC friction material, and the overhaul set is a Precision AS68RC gasket and seal kit, so every rubber and paper part that comes out during a rebuild goes back in new: the frictions, the pan and case gaskets, the lip seals, the sealing rings and the O-rings. That is the wear set that decides whether the rebuild holds line pressure and shifts clean, which is exactly where these units let go when the miles pile up behind a working diesel.

Reuse your steel plates if they gauge flat and are not blued, inspect the pump and the drums, and replace the bushings and any hard parts separately - this is the friction-and-seal package, not the steels, hard parts or torque converter. Set your clutch clearances as you stack each pack, prime the pump, and air-check the circuits before the valve body goes back on. Do it once and the AS68RC takes the torque and the tow weight the way the factory unit did. Ships from the USA; handling in 1-2 business days.
