I am looking for a front / rear differential fluid recommendation and a transmission fluid recommendation. I have a 2005 Dodge Durango 4.7 SXT, AWD, Auto Transmission. Also the manual calls for diff. fluid changes every 15k, this seems kind of excessive to me. It also calls for tranny fluid at 60k, that doesn’t seem like enough. Do I need a friction modifier? Any thoughts? Thanks.

 

I should check my manual as I have 35,000 miles and never noticed or changed the transmission fluid on my 5.7L. You would want to repost this in the second generation Durango section as this is the general forum,

I have a 2003 Durango, and changed the diff fluids at 15,000 miles to get the factory fluid out and put in a good high quality fluid. RedLine. I recommend it. I have had no problems either. I use Mopar ATF+4 Trans fluid when I installed a shift kit in the 45RFE trans.
