AS68RC Overhaul Kit 2006-2012, new and ready to install. Fits the AS68RC. Ships fast from the USA.
A Ram 3500, 4500 or 5500 with the 6.7L Cummins and the Aisin six-speed that weeps fluid from the bell housing, drops into gear late on a cold morning, or starts to flare between shifts while towing is often losing pressure at a worn seal long before the clutches are gone. This AS68RC overhaul kit is the gasket and seal set for that rebuild. The bag in the photo carries the 99002 overhaul kit number, and it is a soft-parts kit only: it does not include frictions, steels or the filter, so a unit with burnt clutches also needs a friction set or a full master kit.
The AS68RC belongs to the Aisin A465 / AS6 family. Transmission Digest explains that its K1 clutch is applied in first through fourth and K2 in fourth through sixth, and K1 apply oil passes the stator shaft in the pump support, which is where one well-known cross-leak starts. The pump, the support, the drums and the valve body are all sealed by gaskets, lip seals, metal clad seals, O-rings and sealing rings, and the piston seals inside each drum hold the apply pressure that clamps the packs. Heat from towing hardens that rubber over time. Once a ring wears or a piston seal leaks, pressure bleeds off before it reaches the clutch, the packs slip under load, and the fluid gets hotter, which speeds up the wear on the remaining seals.
Transmission Digest also describes a stator shaft that turns in the pump body and cross-leaks K1 oil into K2 and the converter clutch circuit. That fault produces the same shift complaints but needs the pump and support repaired, not just new seals, so inspect it during teardown.
Check the fluid level and condition first, then pull the pan and look at what is on the magnet. Fine gray paste is normal wear, while friction material and metal flakes mean the clutches are done and a master kit is the better buy. Our guides to Aisin slipping under load and harsh or delayed Aisin shifts cover pressure testing that separates a leaking seal from a worn pack or a sticking valve. If the truck has been running hot, read our Aisin overheating guide before the rebuild so the new seals are not cooked by the same cause.
This kit is listed for the AS68RC from 2006 to 2012. In Ram trucks the AS68RC arrived with the 6.7L Cummins during the 2007 model year and was replaced by the AS69RC for 2013, so most buyers will have a 2007-2012 Ram 2500, 3500, 4500 or 5500. A published fitment table for a comparable AS68RC overhaul kit lists 2007-2009 Ram 2500, 2007-2010 Ram 3500 and 2008-2012 Ram 4500 and 5500. Check the transmission tag before ordering, compare the old gaskets with the kit, and send us your year and VIN if you have any doubt. Our other Aisin parts are on the Aisin transmission page, and if you need frictions and steels too, the AS68RC master rebuild kit combines them with a full seal set.

No. It is a gasket and seal kit. Frictions, steels and the filter are separate, or you can buy the master rebuild kit if the clutch packs are worn.
No. Ram moved to the AS69RC for 2013, and that transmission takes its own parts. This kit is for the AS68RC used through 2012.
The AS68RC went into Ram trucks with the 6.7L Cummins during the 2007 model year, so a 2007.5-2012 truck is the main application. Send us the VIN and we will confirm before it ships.
Use Mopar ASRC fluid or Mobil 3309, and set the level with the transmission at operating temperature.
Replace the filter, flush the cooler and lines, and inspect the pump, stator shaft and drum bushings. If the pan shows friction material, add frictions and steels.
