About this product

This is the K3 clutch drum, the 3rd, 5th and reverse drum, for the Aisin six-speed found in 2005 and later Isuzu NPR (where it is called the A465) and Mitsubishi Fuso FE and FG trucks (where it is called the AS6). It is listed as refurbished and comes loaded with good used clutch parts, four frictions in the pack, as shown in the photo. If your cab-over truck has lost reverse, slips into 3rd or flares on the 4-5 shift, or a teardown found a burned K3 pack or a cracked drum, this is the part.

What the K3 drum does in this transmission

In this unit three rotating clutches share the work. K1 is applied in 1st through 4th and K2 in 4th through 6th. K3 handles 3rd, 5th and reverse. In reverse, K3 has to hold full engine torque through a low ratio, and on a loaded box truck backing up a ramp it works hard. The drum holds the steels on its inner splines and houses the apply piston. If the piston bore, the drum hub sealing surfaces or the snap ring groove are worn, the pack cannot clamp and starts to slip.

Symptoms of a bad K3 drum

How to confirm before ordering

A failed K3 affects reverse, 3rd and 5th together, which sets it apart from a K1 failure (1st through 4th) or K2 (4th through 6th). Check which gears are missing, pull the codes and look at the fluid. Our ratio code guide covers what P0733 and P0735 mean, and the Aisin harsh and delayed shift guide covers delayed reverse. Also do the return-line check from Transmission Digest. If fluid comes out of the case fitting instead of the cooler line, the stator shaft is turning in the pump. That cross-leaks oil between circuits and will burn the new parts.

Fitment and how to match it

This drum is tagged for Isuzu and Mitsubishi trucks from 2005 on. The listing gives one key measurement: 0.405 inch from the edge of the drum to the snap ring groove. Measure your old drum at the same point before ordering, and count the frictions in your pack. The Ram AS68RC did not arrive until the 2007.5 cab and chassis trucks, and Transmission Digest notes the Isuzu and Mitsubishi versions differ slightly from the Ram one. Ram owners should match the measurement and photo or send us the year and VIN. If the K1 pack also burned, the remanufactured K1 input drum is listed separately.

AS68RC Clutch Drum 2005: common questions

Which trucks does this 2005-up drum fit?

It is tagged for the Isuzu NPR (A465) and Mitsubishi Fuso FE and FG (AS6) from 2005 on. Ram AS68RC trucks begin in 2007.5, so Ram owners should match the 0.405 inch snap ring groove measurement and the photo first.

What does the K3 clutch do?

K3 is the 3rd, 5th and reverse clutch. A slipping K3 usually shows up as a bad or missing reverse together with problems in 3rd or 5th.

Does the drum come with clutches?

Yes. It is listed as loaded with good used clutch parts, a four-friction pack. Many shops still install new frictions and seals during a rebuild.

How do I check the snap ring measurement?

Measure from the open edge of the drum to the snap ring groove. This drum measures 0.405 inch. A different number means a different drum version.

What else should I replace with it?

Replace the K3 piston seals and sealing rings, install a new filter and flush the cooler. Also check the pump stator shaft, because if it turns it cross-leaks oil and burns new clutches.
