DIY: ENG: manual transmission drain/refill

[TypeG]

things needed:
-2 quarts of Honda Manual Transmission Fluid or the equivalent (note: H22 transmissions may require more than 2 quarts)
-17mm socket wrench or regular wrench
-3/8 drive wrench
-new crush washers

first you want to remove the 17mm filler bolt. it is located behind the axle and it has an aluminum crush washer on it. it's a good idea to spray around the holes with brake cleaner to remove grease and dirt that may fall into the hole when the bolt is removed.


you should replace the crush washer every time you take the bolts off. you can reuse them if you have to, but i don't like to, they are like cheap insurance. the crush washer does 2 things: 1) they make a seal when they crush and take the shape of the bolt and housing and 2) that crushing action helps to protect the threads from being damaged due to over tightening.


next, remove the drain bolt. it has a 3/8 square notched into it. you need only a 3/8 socket wrench to remove it (no socket needed). it too has an aluminum crush washer. it is located under the axle.


let it drain and the re-install the drain bolt (remember you don't have to tighten it real tight, keep in mind your putting a steel bolt into an aluminum housing). to fill it back up, you need a funnel and a rubber tube. i use a clear tube, so i can see it going in. fill until fluid comes out of the fill hole (aprox. 2 quarts). make sure the car is level.


then re-install the filler bolt, start it up and look for leaks, and your ready to ride. later.

[Phempa]

thank TypeG..... perfect writeup.
I'll be doing this soon.... but I think I read somewhere that H22 trannsmissions take a bit more fluid than F22. I think cp[mike] has the answer.

nice write up for the noobs..

did you use the new Honda manual transmission fluid??

[TypeG]

nah, i used the old stuff. i asked for the new stuff, but the guy has never heard of it. i told him it had a green lable ect, ect. one of my freinds is a tech there and he's also never heard of it. i'll just have to wait for technology to catch up i guess. later.

I wanna do this.

But where do I go about getting new Crush Washers?

Another stupid question. How do you fill it back up? Where does it go?

Like when you drain oil, you put the oil plug back on, and you put the new oil through the valve cover. Is there somewhere to put manual trans. fluid that I don't know about?

I feel so stupid. Plus it's late, have a headache, and can't think straight.

P.S. I've never changed Trans. fluid before.

you get them at the dealership. you can find aluminum washers at auto parts stores, but you don't have the assurance they will fit.

look at the first pic. the filler bolt is the one that the 17mm wrench is on.

you put it in the filler bolt hole when the filler bolt is remove and the drain bolt installed. you can use a funnel and add it from the top with the aid of a rubber tube. later.

Yo Type G. Once again, I couldn't thank you enough.

I had to bring my car to my friends who work at Jiffy Lube so they could break the top bolt.

Other than that, everything went well, and I can't tell you how smooth my trans shifts now. I'm even running that new Honda Trans. Fluid.

Thanks alot.

you can also use regular 10w30 oil as well
a good way of getting the fluid in it to go to napa or some auto parts store and get a fluid transfer pump
its easier because it can be upside down and may not be as hard to pour in as the funnel, but whatever does the job

[cleanz_28]

you can, but its shitty.

use some kind of MTF. 10x better than any motor oil.

in my opinion, is easier to fill the tranny at the top, threw that small hole.

Can you do that without any problems?
