How to change trans fluid on FD?
i am installing a new clutch and have the (manual)trans off the car. i was wondering how i can change the gear oil in the trans, it looks to me like there are two compartments to fill but i could be wrong.

yup.. just follow the manual. I would highly recommend opening the fill plug first. If you open the drain plugs (there's 2), and can't get the fill plug open, you're kind of screwed. It's not that tough. Depending on what you're doing with the car, I would be careful what fluid you use. I don't want to turn this into a fluid debate either, but gear oil choice is important.
I'm using Amsoil. I won't say it's the best because there's other good options, but I would stay away from Royal Purple gear oil. It's apparantly pretty corrosive to yellow metals (aka synchros). Until i crack my transmission open for service, i won't know for sure, but I believe that's what has contributed considerably to my transmission issues. I have the typical 5th gear syncro problem, but at the last track day, I started losing clean shifts into 3rd as well. Now i really have to be gentle with it.
Here's a link to the discussion thread in the 3rd gen section:

Here's a link to a white paper comparing various gear lubes. Done by amsoil, but seems pretty much on the up and up.
