AS68RC Master Rebuild Kit 2007-2012, new and ready to install. Fits the AS68RC. Ships fast from the USA.
This is a complete Transtec master rebuild kit for the Aisin AS68RC six-speed (also catalogued as the A465) behind the 6.7L Cummins in 2007-2012 Ram 3500, 4500 and 5500 cab-chassis trucks. It is for the truck that is slipping under load, flaring between gears, showing burnt fluid and clutch material in the pan, or simply has the miles and the work history that call for a full overhaul instead of chasing one clutch pack at a time.
The AS68RC builds its six forward speeds from three rotating clutches and two brakes. In Aisin's naming, K1 is the 1-2-3-4 clutch, K2 is the third rotating clutch, K3 handles 3rd, 5th and reverse, B1 is the 2-6 brake and B2 is the low/reverse brake. A worn pack in any one of them shows up as a slip or flare on the specific shifts that pack serves, which is why a heavy-duty unit that has been worked hard usually needs all of them at once. The Transtar catalog listing for the AS68RC master kit (with frictions and steels) breaks it down as an overhaul gasket and seal kit with a fiber pan gasket, friction plates for K1, K3, B1 and B2 plus a further friction set, steel plates for K1, K2, B1 and B2, and a bonded K1 clutch balance retainer. That is every soft part and wear plate you open the case to replace.
A rebuild kit only makes sense if the hard parts are worth saving, so diagnose first. Check fluid level and condition, read the codes from the dedicated transmission control module, and see whether the slip shows up in one gear or several; our Aisin slipping under load guide covers the checks. Pull the pan and look at what is in it: fine clutch material points to the packs this kit replaces, while chunks of metal or a damaged planetary mean you need hard parts as well. The AS68RC and its successor share a known weak spot in the internal wiring harness, where wires turn brittle from heat or pull out of their terminals, which can look like a mechanical failure; our AS69RC problems and service guide explains that failure and how this Aisin family is serviced.
The catalog fitment for this kit covers the AS68RC in 2007-2010 Dodge Ram 3500, 2008-2010 Dodge Ram 4500 and 5500, 2011-2012 Ram 4500 and 5500, and some 2007-2009 Ram 2500 applications. The AS68RC was used behind the 6.7 Cummins in Ram cab-chassis and commercial trucks; most Ram 2500 and 3500 pickups of these years use the 68RFE, which this kit does not fit, and 2013-up trucks moved to the AS69RC. Check the transmission tag before you order, or send us your year and VIN and we will confirm the unit. For the newer unit, compare our 68RFE vs AS69RC guide.

Only if the truck actually has the AS68RC. Most Ram 2500 and 3500 pickups from these years use the 68RFE, which this kit does not fit. The AS68RC was used with the 6.7 Cummins mainly in cab-chassis 3500, 4500 and 5500 trucks. Check the transmission tag or send us your VIN.
The AS68RC master kit catalog lists an overhaul gasket and seal kit with fiber pan gasket, friction plates for K1, K3, B1 and B2 plus an extra friction set, steel plates for K1, K2, B1 and B2, and a bonded K1 clutch balance retainer. A filter is not listed, so order one separately.
Use Mopar AS68RC ATF or Mobil 3309, which is listed as the equivalent for this transmission. Do not fill it with ATF+4 meant for the 68RFE.
No. The AS69RC replaced the AS68RC for 2013 and has different ratios and a revised valve body. This kit is catalogued for the 2007-2012 AS68RC.
Plan on a filter, a torque converter service or replacement, and any hard parts that fail inspection such as bushings, a worn planetary or a brittle internal harness. Flush the cooler and lines before startup.
