Part of the 60k service is to change the transmission fluid. Here's a write up with pics on how to
do it yourself.
Parts & Tools Needed
3 quarts manual transmission fluid
- I used Redline MT-90 because that's what I've always used in my track car
(a turbo 1G DSM) and had good results with it.
Read this 5 speed tranny thread at my.is if you need help deciding on what brand to use.
Some other popular brands are Royal Purple, Amsoil etc
Jack and jack stands
- Remember, NEVER use the jack alone (especially the scissor jack that
comes with the car) to support the car. ALWAYS support it with jack
stands if you're going to be working under it.
24 mm (or 15/16 inch) box end wrench and socket
- You might not need both box end and socket, but for me, it was easier to remove the fill plug with the box end wrench and easier to remove the drain plug with the socket.
Both the fill and drain plugs are supposed to be 24mm, but I didn't have a 24mm box end wrench sitting around so I just used a 15/16 inch and it worked just fine.
As a matter of fact, it seemed like the 15/16 inch fit better than the 24mm.
- Optional if you're removing the drain plug with a socket. Otherwise just double up the box end wrench and you should have enough leverage to remove the plugs.
Washers for the plugs
- You can get these for a few cents at the dealer.
My old ones were actually fine but I used the new ones since I already bought them.
Pump or tubing
- You'll need this to fill the tranny with new fluid.
I used a pump (see pic below). You can get it at any auto parts store.
Here's a pic of the pump (the tubing was clear, it turned orange red after I used it with Redline Shock Proof on the other car):
Pic of the Redline MT-90 (the 2 bottles of 75w90 gear oil is for the rear diff):

Jack the car up and support it with jack stands
Remove the fill plug
This is where you'll need the 24 mm (or 15/16 inch) box end wrench
because the socket won't fit (see pic below).
This has probably been said a million times, but make sure you can
remove the fill plug before you drain it.
I made the mistake of draining first when I did my other car and well,
sure enough Murphy's Law kicked in and I ended up spending the next
3 hours filing down a rounded off fill plug (what started out as a
17mm plug wound up as a 13mm plug by the time I got it off)
Remove the drain plug and drain the transmission fluid
I used the 24mm socket and extension here because it was kinda awkward
getting the box end wrench in there (you'll see what I mean once you're
down under the car). I suppose you can do it with the box end wrench
if you remove the plastic shield.
By the way, you might wanna move back a bit before you remove the
plug completely because the fluid will gush out and a good amount
will most likely end up on your face (don't ask me how I know this)
Let the old fluid drain completely and replace the drain plug
Go take a break (or wash your face if you messed up doing step 3)
and let it drain for a while, then replace the drain plug. Dont forget
Fill with fresh tranny fluid
Shove enough of the tube into the filler hole so that it sits
firmly and won't fall out when you pump new fluid into the tranny.
Here's a pic:
I had to cut the top off of one of the bottles because the pump wouldn't fit in it:
I kept pumping fresh fluid into it until it started dripping out. Ended up
using nearly all of the 3 quarts of the transmission fluid.
Replace the fill plug
Since I didn't want to lose any of that precious MT-90,
I temporarily plugged the hole with my thumb with one hand while I was
grabbing the fill plug with the other. Tighten the plug and you're all done!
Perform this procedure at your own risk! As easy as this is and as accurate as
I've tried to make this guide, I'm not responsible if you screw up and mess
up your car!
