My 2004 owner's manual specifies Mercon for the power steering and manual transmission..Is Mercon V the current spec?
The manual shows two weights for the differential.Is 75w-140 syn the correct one for the GT posi rear?
Thanks.

merc v or equivalent for PS and trans, and yes 75-140 is the correct fluid, dont forget friction modifier

Do you still need friction modifier when using Royal Purple?

jwog666

if the royal purple specifies that it has friction modifier included, then no. otherwise always use modifier

Even with RP which I hear contains a friction modifier I would still invest the extra $6 on a bottle of f/m and put it in anyway.

So it won't hurt it to ad more than what's in the rp?

i dont see it being a problem
