I just installed NEO 75W-90 RHD in the newly rebuilt Miata geared transmission.
Not really satisfied with the noise in 4th gear, Considering/thinking about changing to 80W-140 EP

The transmission is smoother as a result of the new fluid. If that's because it's synthetic I don't know for sure. It seems happier in the cold switching from 80W90 to 75W90. It doesn't seem to get as hot either, but that's not exactly a scientific analysis.

I like Red Line MT-90 in the transmission, and 75w90 in the differential.

Other good synthetic oils:

http://www.neosyntheticoil.com/
http://www.royalpurple.com/
Synthetic wheel bearing grease is also excellent. I have used Mobil 1 for many years with good results, but the brands listed above also make synthetic wheel bearing grease. Just a few days ago I picked up a tube of Royal Purple grease to try out.

sold--no longer in debt
I used to have a grind down and up shifting into 2nd gear.. I switched to Redline MT-90 (bought it at summit racing, like 30 mins from my house) and the grind has ever since been gone.
