transfer case - what fluid?

[scha0786]

what fluid am I suppose to use in my transfer case now (For an 04')?

The ford motocraft ATF is discontinued and the dealer told me to use Mercon V, but if you read on the bottle it says, "Do not use in Transfer Case".

Should I use this stuff, ford part number XL-12

Transfer Case Fluid

otherwise I will order some amsoil atf up

thanks

AMSOIL ATF is compatible with both Mercon and Mercon V - This is what I would recommend. I think the Mercon V is backward compatible to the Mercon but I personaly would have a hard time putting it in my T-case if it states on the bottle to "do not use in T-case" You think they would get that updated before recommending this.

Let me know if you would like a quote on the ATF

thanks for the info, what I would like to know is if the XL-12 is safe to use in my 04' transfer case because I already bought that from ford, not saying that I can return it but it just is a hassle to return.

I got this from a different forum. Apparently bd is a "Ford Master Parts Counterperson" according to his Sig. It seems that every dealer is different on what they recommend

bd - do you know what this fluid is exactly? It looks to be the same viscosity of an ATF. What kind of additives are in it? I thought that Ford recommended ATF in the tcase...?


its basically the old Mercon. they just call it transfer case fluid since Mercon is an obsolete spec in all transmissions from ford.

thanks for the info, I will most likely just use the XL-12 stuff since I have it and seems to be safe in transfer cases. maybe next time I'll switch to amsoil

put in the XL-12 fluid and everything seems ok
