DIY: Manual Transmission Flush/Replacement
DIY estimated time: 20 minites
Tools Needed: 3/8inch wrench, 17MM socket, funnel (from Homedepot), 4 Jack stands, and a jack.
Step 1: Once the front of your car is up on the two jack stands, get out your funnel, wrench, and 17mm socket.

Step 2: Look underneath the front of your car. You will see something similar to the picture below(maybe a little cleaner
):

Step 3: Place the wrench (without any socket attachments) into bolt #2. As you can see, bolt #2 has a hole in it that fits your wrench perfectly. Unscrew the bolt by turning couter-clockwise. Have a small bucket to catch all the manual transmission fluid about to pour out of where socket #2 is located. Once all the fluid has been drained tighten bolt #2 back on to the transmission.
Step 4: Using your wrench with a 17MM attachment as seen below,

Unscrew Bolt #1 (as seen below) by turning counter-clockwise.

Step 5: Have a person stand next to your car and hold the funnel as seen below.

Place the end of the funnel into the hole created by removing bolt #1. Tell the person to put the manual transmission fluid into the funnel. Once 1 quart is done tell the person to start on the second but pouring very slowly. Once about 60% of the second quart has been used, the hole from bolt #1 might start to overflow.
Step 6: Take out the end of funnel and put bolt #1 back on and screw it in.
I used the Honda manual transmission fluid. I bought 2 quarts.

I would advise the use of FOUR jackstands so the car sits level and you get enough tranny fluid in there. If you leave it on an angle, you'll overflow before you should and won't have enough in there.

I think changing the gearoil every 30k is a much better idea. I changed mine at 24k because of notchy shifting. BIG improvement. 30k is reasonable for any car. I'll change mine again when the transmission starts feeling stiff, or 30k. Whichever comes first.
Don't believe the manual. It's designed for people who trade in their cars every few years. If you plan to keep your car only 3-5 years, it's fine. It'll be trashed for the next guy. Oil is cheap.

Only thing I would do is undo the fill plug before the drain plug. That way, you can make sure you can put in the fluid. Id recommend redline mtl if you guys like to mash on your trannys a lot like me

Storm - did that funnel actaully come with the long hose attached? I saw what looked like the same funnel at Wal Mart but the hose was much shorter. Thanks.

Re: DIY: Manual Transmission Flush/Replacement
sorry to bring back a really old thread, but is the stuff I would be looking for? Everywhere else I keep seeing different viscosities of transmission oil and such, but I think this is what I'm looking for, if not, maybe someone can point me the right direction as far as which fluid to use, thanks!

Also don't forget that whenever you tighten your drain and fill bolts it's recommended that you torque them to the correct amount. For example, for the EP3 w/ K20a3 the fill bolt is 44 N-m/33 lbf-ft and the drain bolt is 39 N-m/29 lbf-ft.
Sorry but for yours your gonna have to look it up. I looked in my shop manual, if you don't have one you might be able to find a free one online like I did. Or just keep searching around to find out what it is. Kind of obscure information to find though, good luck.
