Neo 75w90. I have used it successfully for many years in my rx7s trannys and diff. Works wonders.

LoL...I was hoping this thread had some answers too! I was just about to put trans and diff oil in to my FD and hopefully start it up. Would it be too much to ask for just a quick answer to the grade of oil used. I think for the trans I was told something like 75w90. Does that sound right? What about the diff? Help us out pleasssseee...

Gordon, you know if they have this stuff at local automotive shops? I'm sick and tired of ordering little things like this and waiting a few more days to finish and start my FD. These *little* things have all added up to over an extra month wait to start the car. It's sooo annoying...

MT-90 in the trans. Any good GL-5 in the diff. 75w-90 per the FSM.

My local stores are now carrying Redline and Royal Purple. Pretty cool, but unfortunately they didn't have more than 2qt of any one kind. :/

i also use neo 75w 90, shifts are noticeably smoother, differential feels better too.

I order mine from http://www.hankthomasperformance.com/ It cost me 43 bucks shipped for a 1 gallon of 75w90. Which is enough to do the tranny and diff.
