Ok, I've gotten the tranny out now and we're working on changing out the clutch. what kind of transmission fluid do I need to put back in it? My owners manual says "Manual Transmission Gear Oil: API GL-4". I don't know what that means. Can someone please help me?

Thank you.

 

Make sure you replace only with API GL-4. GL-5 or GL-3 will ruin your transmission.
