Ram Asin Trans fluid

2014 here. I used Mobil 3309 atf after searching turbo diesel register and other CTD sites. I bought the Chrysler transfer case oil on Amazon and run Mobil 1 in the pigs. DO NOT mix up the coolant. There are a few different ones and mine uses HOAT. It specifically warns about using the exact coolant. It may appear orangish at times depending on the light angle but it's purple. I bought it at the dealer.

Did you download the diesel supplement?

Look on AMAZON. Great deal on OE Mopar fluid delivered to your door $44.76 per gallon.

Changed the fluid on my son's 3500 RAM last weekend. Draining JUST the pan 8 quarts came out. Removed the pan and filter an additional 2 quarts came out. I popped the line at the radiator but only a little over 1 quart came out before it turned RED. So we removed about 11.5 quarts out of 13.7 total fill.

The 3 bolts holding the trans to the cross member need to be removed and raise the trans up tim it stops to get to the 4 bolts at the front pan. NOT an easy task!!!

My Son used the AMZ/OIL ATF.

X2 for the Mobil ATF 3309. I believe they say its a 6.8 quart change. I used a full 7 quarts, FWIW.

7 quarts out of 13.7 is not much of a "change".

Not to the point of having to change it yet but thought I'd look ahead to see what others were doing after seeing a comment of someone getting charged about $500 for a fluid change! Seen they run special antifreeze also so I'll be getting some of that too. Thanks for the insight Cummins12V98 on changing the fluid!

Just following the manufacturer's recommendations for service at the specified intervals. Next "change" will be a full "change".

Mobil 3309 is the correct fluid.

Book says to "change" at every 30K does not say partial. Book says to change filter at 120K.
