Transfer Case Fluid

[Blac Trac]

Its time to replace my Transfer Case Fluid in my 2005 Trac. My manual says MERCON only. Is MERCON V OK? What is everone else using with success?

Do not use in transfer cases where MERCON ATF was previously recommended

swshawaii,

Thanks for the Motorcraft Fluid Data Sheet Link. That confirms that FORD still is advising not to use MERCON V in Transfer Cases where MERCON was recommended previously

* Do not use in transfer cases where MERCON ATF was previously recommended

What should I use? Any help please?

 

[swshawaii]

Use the original Mercon ATF (1.3 Quarts)

MERCON and MERCON V are not interchangeable. DO NOT

mix MERCON and MERCON V.

I called 2 of my local Ford Dealers last week and both told me MERCON is not available from Ford anymore. They only sell MERCON V. What is everyone else using in their Gen 1 Tracs?

I have used what is labelled dexronIII/mercon. It is the only thing I could find. It figures that we need a specific fluid, and it is no longer made.

After doing some availability searching at my local PSs and looking at on-line spec sheets, I'm leaning towards VALVOLINE DEX/MERC ATF as it is a mineral based ATF supporting MERCON requirements. I also looked at VALVOLINE MAXLIFE DEX/MERC ATF but it is synthetic and while it supports MERCON requirements Valvoline says it also supports MERCON V. To me that kind of reads like its OK to use MERCON V in place of MERCON which is what I was trying to avoid so I guess I'll use the regular VALVOLINE DEX/MERC.

I use Mobil 1 ATF in mine. It is rated for both Mercon and Mercon V use. Put it in both my Trac's t-cases and the Ranger I had before, no problems.

Are the Gen2 Transfer Cases different from the Gen1 ones?
