Which fluid for '91 Explorer 5 Spd?

[Mark-in-CO]

I am finding conflicting specs for the manual trans and transfer case fluids for my '91 Mazda Navajo (aka Explorer). I have seen either 75W-90 gear oil or Mercon/Dexron.

Which fluid is right for the 5 spd tranny?

Which is right for the transfer case?

The Mazda Tranny uses Mercon/Dexron III. The diffs use 75W-90.

Thanks! Mercon/DexronIII for the transfer case as well?

You could use our MTFGlide for both the tranny and transfer case.

MolaKule is correct. Use of the SF fluids will aide your tranny and transfer case function over the factory grade fluids. I use SF's full synthetic SynchroGlide in my troublesome 2002 F-150 with the Mazda 5 speed tranny. It helped greatly with it versus using a Mercon grade fluid. I also use SF's full synthetic diff 75W-90 in my rear diff. I don't tow and have an open diff so the 75W-90 full synthetic works fine for me and hopefully saves a bit on gas. Check with MolaKule as to what type/grade of SF is best for you. He's a site sponsor and very helpful as to catering to our individual needs. I'm more than happy with MolaKule's service and products.
