I can tell you that I just went through my WC T-5 which the previous owner had used gear lube in and sure enough, my upshift gear grinding was due to this material being badly worn. I plan on using Mobil 1 ATF.

BTW - This only applies to WC T-5's - non-WC versions due not use the fiber lined rings.

There are a few ways to tell a WC from a non-WC. The easiest for me is to look at the front countershaft bearing cup. A WC will have a bearing race type cup with an external bearing (Timken) type number stamped in it. The non-WC version is just a plain, flat cup. Hard to explain without pics.

Of course, this ID aid would require the trans to be removed. I believe I have a .pdf of a T5 manual somewhere that explains some more ways to identify a WC trans. Let me know if you need more help with it.
