Make sure what ever you get is GL4, NOT GL5.

Good luck finding a 'regular oil' that is 75W-90 GL4 (what the sr20 transmission takes). Practically all the transmission oil you'll see at auto parts stores is 'gear oil' and is GL-5. This stuff supposedly eats soft metals, ie brass or copper, which includes our synchros.

You could spend more money in wasted gas driving around finding that stuff than you would just buying redline or royal purple. I'm running royal purple and its awesome!

you fill it up at where the speedo pinion is -----there is one small bolt to remove and be careful because the gears are plastic when you remove it. You sholud remove your intake because it makes it s alot easier to get to. Buy a funnel and get a lone plastic or rubber tube to pour the fluid in. Our trannys take almost 4 quarts so just pour all of it in. I use MT90 from redline because I know it does not eat our soft metals in our trannys

so its on top of the tranny and underneath the intake? awesome! thanks alot
If you want to do it the hard way, yes. :) There is actually a 3/8" fill plug on the front of the transmission facing the radiator. Fill it with oil there until in starts to flow back out (with the car level).

Its easiest to do it with a funnel and a couple feet of vinyl tubing.

If you just want plain ol' GL-4 gera oil, here is what I did. I stopped by one of those local quick change Valvoline shops and asked them if they had any. They went in the storage room and found a brand new unopened 5 gallon container of Valvoline Hypo GL-4 Gear Oil 80W90. There was dust all over it.

They gave me 2 gallons in a plastic gas can for $20. I now have enough leftover after my clutch job to do another with no problems.
