Ok, at the last autocross, just before my first run, I noticed that I had a torn CV boot. I ended up going home to work on the car vs. staying for the rest of the day (yes I did work!)

So I ended up replacing the axels with rebuilt units. But I just noticed today that I am leaking fluid from the passenger side transmission seal. In the back of my mind I “knew” those probably should be replaced when I did my axels, but I didn’t. I assume that a combo of age and me removing/reinstalling the axels caused the leak.

Of course, this entire issue ruined my autocross last time and now this happens just a few days prior to the next one. Who knows if I am going to get it fixed in time.

Anyhow, is it as simple as…

1. Drain transmission
2. Remove axel
3. Note how deep the old seal is.
4. Pull out old seal using some type of seal puller.
5. Clean up surface on transmission.
6. Pound in new seal (make sure it goes in perfectly straight) with rubber mallet to proper depth
7. Clean up surface on axel, and lightly grease axel stub
8. Reinstall axel
9. Replace fluid

I know all of the Civic specific tricks on getting axel out, replacing transmission fluid, etc. But is there any special things that I need to do for this seal? Is the seal supposed to have any other sealant applied prior to installing it? Or is it just rubber to metal? If just rubber to metal, do you lightly lubricate it before pounding it in? Or just do it dry?

Should I use a Honda OEM part or does someone like Autozone, etc. sell a decent replacement part for this that I can trust?

Same info is posted on Honda-Tech, but since we have a few DIY Honda guys here I figured it couldn't hurt to ask.

-If you are careful you can skip #1, just do 1 side at a time
-Skip #3, just tap it in until it stops, it wont go IN the transmission
-No special tool needed to remove, flat headed screwdriver works fine

I would coat the seal in some sort of oil, transmission or motor other than that have fun!

My experience (and I am sure my brother will agree)...go with Honda OEM parts.

Ok, thanks guys.

I probably will skip draining as since it is leaking, who knows how much I have left and it probably would only leak a bit if totally full. It is just wet and not a huge puddle under car so hopefully it has not leaked much. Car and I am at work, so I am going to risk driving it home. Probably been this way for a week.

Crown Honda at Southpoint (just a few miles from my house) has the parts in stock. So I will get the Honda OEM from them.

If all goes well, I will still be able to make it on Sunday. I DO have a new mystery sqeak on the right front. Sounds like a squeaky bushing (never has done that before). My luck I will discover I have blown out a shock or something.

When I did mine I was surprised that the seals were different sizes! You would think they would be exactly the same but they weren't. Whatthe heck was Honda thinking? Anyway, something to be aware of.

And yes, its as easy as the others have pointed out.
