For fyi, your coolant is 5 year Chrysler HOAT. Your owner manual here.

Front and Rear Axle – 2500/3500 Models

Synthetic, GL-5 SAE, 75W-90 or equivalent. Limited-Slip 10.5/11.5 inch Rear Axles Limited slip additive is not required.

Transfer Case MOPAR ATF+4 Automatic Transmission Fluid or equivalent licensed ATF+4 product.

Transfer Case – BW44–44 Only MOPAR BW44–44 Transfer Case Fluid or equivalent.


I like redline c+ for your transfer case, that is what I use in mine as well, even for the 44 we have guys try those unicorn tears 44 fluid and amsoil and redlne, just go redline c+, less then 3 quarts. @Hemi395 used all options in his 2012.

For gear fluid I like amsoil sg in the bags, or you can use redline 75w90 you do NOT want NS in the title, that is for older gear boxes not for 2012 gear boxes. Less then 3 quarts per diff for 1500, not sure if it is the same for 2500 diff.

I use Walmart Synthetic gear lube in my truck's diffs. It's inexpensive and I've never had any issues with it. I've probably used it for close to 15 years, maybe 20 in various vehicles that I've driven tons of miles.

I use the proper Mopar fluids in the transmission, xfer case and power steering (from Chrysler). Amazon sells them. By now some of the numbers may be superseded, I'm not sure. But non-Mopar +4 would probably work fine. It has to meet the specs.
