Honda Civic Automatic Transmission Oil Plug keeps coming out

- The automatic transmission fluid (ATF) plug in my Honda civic 2014 kept coming out even though I inserted it securely. It was a miracle I didn’t lose it while driving. I would be checking the oil and all of a sudden the plug would be out again.
The root cause was that there is a small rubber piece that allows the pressure in the ATF to be released but it was clogged with dirt. Therefore it kept pushing the ATF plug out.
I cleaned the rubber piece to allow the pressure out and put it back in the two o’clock position (rather than facing forward like it was) to avoid dirt clogging it again. I think it is called Transmission Rubber Breather Cap with part number 21396-P20-000.
Since then, the ATF plug never came out again.
Other people in the comment suggested to replace the plug with an original Honda in addition to cleaning the small rubber piece. I bought this one from Amazon for $12: a.co/d/bR16SYM
I measured the diameter of the new one and it was 20.7 mm. The old one that kept coming out was 20.24 mm.

youtube is amazing for stuff like this. I had this problem as well and my mechanic had no idea why the plug would have popped out. I checked my pressure vent piece and it was clogged just like yours
I am so glad it helped you.

Nice. My plug popped out once. I checked it recently and it's still there, but it seems to be leaking all around it so I'll check the vent plug next.

I can see you also watched the other video. At the end, you will need a new plug or risk popping it out again in the future.

I bought this Civic 2014 May 2023 with 200,000 miles. I could not find the plug, so I ordered one. Trans was slow until it warmed up, then it was ok. I added a quart just incase that was the issue, and it worked great. The following week I decided to change the fluid. I drained only 1 1/2 quarts of trans fluid! I put in 3 quarts to the overfill hole, so it was very low of fluid; but I got a great deal on the Civic because they thought the Trans was going bad. I found the original plug on top of the trans housing. Thank you for your video! I removed the vent today and it was clogged. ❤
Love to hear stories like this. I am happy for you. Check my other videos for the 2014 civic I have. You can clean the MAP, MAF, change the PCV valve, etc and the car will run perfectly fine.
What's the name of this little cap?
@backtoys Do you mean the little rubber piece that was blocked?
That is a Transmission Rubber Breather Cap. And I think the part number is 21396-P20-000

@@gotitdone Yes!! Thank you very much. 🙏🙏🤝
Just had the same problem, thanks for the informational video!
I am glad I could help you!
Mine kept popping out even after cleaning the vent think it got worn from popping out to much / solved this issue by buying a USA version of the plug from eBay it’s a bit thicker then the oem one it’s very snug and never had a issue again I clean the vent still every so often so nothing happens to the new plug , hope that helps anyone that was having this issue still even after cleaning the vent
Thank you very much for your comments and suggestion. I didn’t find that part in rockauto.
Great Answer… I got this Car & Just Found the transmission plug… Honda is full of 💩… after they make the sale.. you on your own..🥶
I bought this one from Amazon: a.co/d/dA1Olz5
And updated the description with this information. Thanks again!
I got one from there but it’s super hard to get in is that normal? I tried turning also any tips would help thanks
@@Woods1999 you got a new plug from the link I provided? I didn’t have any trouble inserting it on my 2014 civic EX
I found my filler plug out on top of my tranny and was wondering if a clogged vent somewhere created pressure that forced this out. You answered this question, and I will now pull out the vent cap and deal with it. Thank you.

Glad to help
Happens on 15 civic for sure . I had to wrap mine in tape to get snug fit
Clean the vent then get a new plug as the rubber on the old plug gets soft and is prone to popping out
That is correct. I actually measured the different plugs in this video
th-cam.com/video/ERv_O5Z18yI/w-d-xo.html
@@gotitdone yes indeed some time simplicity is the best fix make an old rubber part fit like a new rubber part doesn't always work
I thought my local mechanic forgot to put back the TR plug, I was so upset.
Was the rubber piece plugged?
@@gotitdoneYeah and I actually checked it now, it's unplugged again and dirty. I cleaned the vent as well. Tomorrow I'll do a clean and change TR fluid.
Because just yesterday, my coworker noticed my TR is slipping. Didn't know this popped plug is quite common.
Thank you for the video, it really helped!
@@gotitdone You didn't even watch the video or you wouldn't have best that question
Hey Sir! Can you name the rubber part!! It’s kind broken in my car! Need to get new one!! Please help me on it
You mean the small “breather”?
It is called Transmission Rubber Breather Cap with part number 21396-P20-000.

: Great backyard mechanic fix.
But if you don't mind spending a few extra dollars, you can replace those 2 parts with new ones from Honda. (FYI)
Yep, original parts were a total of $30. Thats what i did.
@aphoenix9349 agree. I replaced the plug.
Check this other video I did:
th-cam.com/video/ERv_O5Z18yI/w-d-xo.html
If that cap is off long enough can it cause fluid to leak out and drip down the bottom?
I have seen some fluid coming out but not enough to drip. Anyway, if the cap has been off for a long time I would check if the fluid is at the right level.

@@gotitdone so I replaced it and yes it was super gunk up but my plug still coming out.
@@topwing211 then it is because the plug already shrank a little bit and cannot hold the position anymore. Check the description of the video. Towards the end I explain that a new plug was slightly thicker to stay snug into position
Pls help the fill in plug keeps popping up out even after I clean the vent plug what should I do ? Replace the filll plug ?????
Unfortunately, yes, you have to replace the plug. The reason is that it kept popping up because the diameter shrunk a little bit already. Read the description on my video because I remember that I explained that exactly and the part you have to get.

I got 2015 honda civic. I got check emissions light on and check transmission sign on the dashboard.
Any one knows what would be the likely problem?
Have you checked the code numbers on the OBD port? Was your ATF plug coming out? If that was happening you should check the ATF level.

Will that lil clogged pressure cap cause it to not move? And with the dipstick cap off and not knowing will the fluid evaporate cause ain’t no wet spots under the hood or on the ground.
@@BeenHadEnt when the pressure cap is clogged, the transmission fluid will get pressure and pop out the plugs. Some fluid could get out but won’t drip, so don’t expect wet spots
@@gotitdone will the clogged cap cause the car not to move ?
@@BeenHadEnt I don’t think so. The internal pressure will be released through the plug. That is why they pop out

I noticed my transmission slipping, I checked it and the plug was missing. I removed the breather and it was so old it cracked. What happens if you simply dont replace the breather ?
I suppose leaving it without a breather is better than being plugged but I would still replace it. It is a cheap part. I added it some time ago to the description of the video.

Question. When the cap would pop off, would it spill out oil and if it did, did you car smell like burning oil?
It didn’t spill too much ATF fluid. I could see a little bit of a mess around that area. I put back some fluid to ensure the correct levels for the transmission to work properly.

Seems to me that the little plug would blow off easier could something else be going on I’m having this problem as well
In my case it was the vent that was fully blocked since it was facing forward.

Will this cause the checking engine light to come out by any chance? I was double checking the engine after the CL came out for the first time and I wonder if it’s this, especially since the scanner is not giving me an specific code for the issue.
I didn't get any codes when it happened to me.
I would imagine that if the transmission fluid gets too low and the transmission gets too hot you would get a code but for that to happen you would have to be losing fluid for a while and driving like crazy.

One question! I found my filler plug out and fortunately, oil did not pop out from it. BUT I found the something broken acorn shell in there!! I tried to pull it out but it was going inside more now! Do I need to drain then the acorn shell will come out? Or is it okay to leave it?
I have never heard of the rubber plug breaking into parts. To start with, I would replace the plug with an original Honda in addition to cleaning the small vent. I bought one from Amazon for $12: a.co/d/bR16SYM. Then, I would change the ATF fluid once to see if those small parts come out.

This video explains how to change the ATF fluid: th-cam.com/video/DU1aFb4iARQ/w-d-xo.htmlsi=bUs8LSJmR7UJal95
I mean that I park my car outside most of the time, and acorn shells had accumulated quite a bit under the battery area. At that time, the transmission oil plug was have popped out, and one of the acorn shells got into the hole(A squirrel may have gotten in). Anyway, you recommend changing the transmission oil fluid in this case, right? I already replaced the plug and cleaned the small vent now, and the only concern is that a small piece of acorn shell is still in the transmission tank.
@@wkhong3996 got you now! I think the only thing you can do now is replacing the fluid and see if any pieces come out the ATF drain plug. That process cannot harm anything and should cost around $50. I would think the acorn would be shred into tiny pieces inside the transmission. Not that I like the idea but you won’t be able to fish those acorns anyway.
@@gotitdone Many thanks!!
So what is the smaller whole next to the plug?
Do you mean the whole for the rubber vent that gets plugged?
this doesn't fix the problem yes you should keep the pressure vent clean but this happens when the rubber transmission plug shrinks from the heat over time it needs to be replaced.
I think it depends. It worked for me since the vent was completely blocked (like mine) and the plug is still snug. But you are also right, if they plug is not snug anymore cleaning the vent might help but the plug will eventually come out and you will be required to get a new one to be snug again. Somebody mentioned that in another comment.
@@gotitdone Its a cheap part best to just replace it when you clean the pressure valve it's not worth the risk of the plug popping again.
Following your suggestion I replaced the plug with an original Honda from Amazon for $12: a.co/d/bR16SYM
I measured the diameter of the new one and it was 20.7 mm. The old one that kept coming out was 20.24 mm.
Thank you!
