What weight 75-90? 75-110? 75-140? I assume no additives are needed for a spool?

No additives are needed. especially with that oil. I run the 90 in my cars and we even run it in sprint cars with great results

dexron 6 in the trans and royal purple 75-90 in the rear end.

Why dextron6 you would think auto trans fluid would just burn up the manual trans? I would think to use the same 75 -90 as the rear.

nope, many manuals now come factory with some form of atf. I believe some aftermarket trannys also call for atf.
