About this product

This is a clutch drum for the Aisin AS68RC, the six-speed automatic Ram put behind the 6.7L Cummins in 3500, 4500 and 5500 chassis cab trucks from 2007 to 2012. It is listed in used condition. If your rebuild stalled because a drum came out with burned spline teeth, a cracked or blued shell, a scored piston bore or a bushing that has walked, this is the hard part that gets the unit back together without waiting on dealer back-order.

What a clutch drum does in the AS68RC

The AS68RC builds its six speeds from three rotating clutches (K1, K2 and K3) and two brakes (B1 and B2). Each rotating clutch has a drum: the outer splines hold the steel plates, the inside of the drum houses the apply piston and return spring, and fluid fed through sealing rings pushes the piston to clamp the pack. If the drum leaks, the piston cannot hold full force, and the pack slips and burns. The K2 pack is the one shops see fail most on this unit. Sonnax describes AS68RC K2 failures from limited clutch capacity, showing up as a burned K2 and no 4th, 5th or 6th gear, and sells a piston kit that adds a plate to that pack. Heat from a slipping pack is also what cracks or distorts a drum, so a drum often goes into the unit along with new clutches.

Symptoms of a bad AS68RC clutch drum

How to confirm it before you buy

Start with codes from the transmission control module and a note of which gears are missing or slipping, then check the fluid. Our Aisin slipping under load guide covers the in-truck checks, and the Aisin overheating guide explains how heat kills these packs on towing and upfitted trucks. With the unit apart, inspect the drum under good light: check the spline lugs for notching, the piston bore and sealing surfaces for scoring, the bushing for wear, and the shell for heat cracks. Air-check the assembled pack before it goes back in the case.

Fitment

This drum is for the AS68RC used in 2007-2012 Ram 3500, 4500 and 5500 chassis cab trucks with the 6.7 Cummins. It does not fit the 68RFE found in most Ram 2500 and 3500 pickups of these years, and the 2013-up AS69RC should be confirmed separately. The listing does not say which of the three rotating clutches this drum belongs to, so compare it with the drum you removed: outside diameter, spline count, the piston bore and the hub before you order. If you want it checked, send us a photo of your old drum with your year and VIN. For a known-year unit see our 2007-2010 AS68RC input drum, and browse the rest of our AS68RC parts under hard parts.

AS68RC Clutch Drum: common questions

Which clutch pack is this drum for?

The listing identifies it only as an AS68RC clutch drum. Compare its diameter, spline count, piston bore and hub with the drum you removed, or send us a photo with your year and VIN and we will confirm it before it ships.

Does it fit my Ram 2500 or 3500 pickup?

Most 2007-2012 Ram 2500 and 3500 pickups use the 68RFE, not the AS68RC. The AS68RC was used in 3500, 4500 and 5500 chassis cab trucks with the 6.7 Cummins. Check the transmission tag before ordering.

My truck has no 4th, 5th or 6th gear. Is it the drum?

That pattern usually means the K2 clutch pack burned. The drum may be fine or may be heat-damaged; inspect it for cracks, blued splines and a scored piston bore. If it is damaged, replace it along with the K2 frictions and steels.

Is a used drum safe to install?

A sound used drum works the same as a new one if it passes inspection. Check the splines, bushing and sealing surfaces, install new seals, and air-check the pack before the unit goes back in the truck.

What fluid should I use after the repair?

Mopar ASRC fluid or the Mobil 3309 listed as its equivalent. Flush the cooler and lines first so debris from the failure does not reach the new clutches.
