Tomorrow im going to replace the fluids in my read differental, T case and 6 spd trans. Im looking for a spec sheet for how much fluid each one takes.... Also what do you like for fluids??? I also have a LS axle do I need friction modifier like ford does?? If so will any brand work?? Thanks!!

 

btt............

 

I just did my differentials and needed a littel over 6 quarts for the front and rear. It was close to 2 quarts in the front and 4 in the rear. I used Chevron Delo ESI 80W90, still a dino oil but I like it and less than $4/qt. You will need limited slip modifier, but don't just dump it all in. I found some direction on this site to put in the oil and the find a lot to drive slowly in figure 8's. The inside tire should chirp on you while the limited slip tries to make it turn and break loose. Add the limited slip additive 1 ounce at a time untill it quits chirping. It only took 1-2 ounces for mine. Haven't done my transfer case yet, but I think it takes 2 quarts of ATF.

 

I switched out the stock fluid (I think) at 55K miles to the Redline MTL. I pulled the shift boot and poured it in thru the top as suggested by someone else on this site. Easy. I put 6 quarts in and immediately noticed smoother shifting. No leaks. I drained the old fluid out thru the bottom bolt of the drivers PTO cover. Again, Easy. I'm happy w/ the Redline MTL, but only can compare it to 55K old stock (I think) fluid. Hope this helps! Kurtaing
