Raspy I've always used the Mobile ATF 3309. It's easy to order on Amazon. 6-7 quarts to re-fill, after each pan drain.

The AS68RC transmission (only used in 3500, 4500, and 5500 Cab & Chassis trucks from 2007.5 through 2012) ran AS68RC fluid.

With the introduction of the improved and more robust AS69RC transmission in 2013 (used in Cab and Chassis trucks AND 3500 pickups) the name of the fluid was changed to simply ASRC fluid. Essentially......it is the same fluid, but is backwards compatible to 2007.5 The name was changed to eliminate any specificity of the older AS68RC fluid.

I order some stuff from Rock Auto.....just beware of some of their shipping charges, especially on heavier items like fluids. Sometimes all of the savings go away with the shipping. I have had great luck with a a few eBay and Amazon sellers purchasing cases of 12 quarts of the Mobil 3309 fluid.

Jhenderson Your trans is an Aisin AS69RC. Thatís the correct fluid.

Jimmy N. Mine has less miles on it than that, in about the same amount of time.
If I wanted to change the fluid, I'd order some and do it. But it still appears to be perfectly serviceable, so I won't change it anytime soon.

That doesn't mean I couldn't order the fluid today. Then, if one day I wake up with an irresistible urge to change it now, it'd be there ready to go in the trans.

3500newtome Right?!?

Actually truck has only 14k miles, but 27 months. My schedule is pretty tight and I donít see any open days in the next two months to get this done. But I will keep those sources in mind for 2021!

It's interesting how those last 30,000 miles can sneak up on you. On Monday everything was fine, yesterday the fluid change was imminent.

dillonjm Which is the same thing....

pwr2tow Or you could buy the Aisin fluid from rockauto for $4.95 a quart.
09-04-2019 08:46 PM
Jhenderson Of course you could just buy Mobil 3309 for $5 a quart from Summit Racing but I guess that makes too much sense.

3500newtome $16.63 for MOPAR at the dealership vs $6.30 for the Toyota ATF Type i-iv at the dealership. So unless you all tell me this is the wrong fluid, Iím off to save $10 per quart...
