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

You mean the small “breather”? It is called Transmission Rubber Breather Cap with part number 21396-P20-000. This is a good place: honda.oempartsonline.com/oem-parts/honda-cap-breather-21396p20000 I recommend replacing the ATF plug as well: honda.oempartsonline.com/oem-parts/honda-cap-filler-atf-a-cvt-256155t0004 Please consider subscribing to my channel or a $thanks.

Thanks for your quick response!! really appreciated!! will update after changing the parts 😅

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 Please consider subscribing to my channel.

@@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

@@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

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

Thank you for your kind words and I am glad I could help you. Make sure you read the description of the video. I added information about the part number, etc

Unfortunately, yes, you have to replace the plug. The reason is that it kept popping up because the diameter shrunk a little bit already.

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.

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.

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.

What is the cap called so that I can order one

@@adrianasamaniego9856 I replaced it 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 was 20.24 mm.

​@@gotitdonethat was quick! Thanks and subbed

Glad to help

Happens on 15 civic for sure . I had to wrap mine in tape to get snug fit

That is correct. I actually measured the different plugs in this video ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-ERv_O5Z18yI.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 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!

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. Please consider subscribing to my channel.

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!!

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.

Do you mean the whole for the rubber vent that gets plugged?

I really hope you are kidding 😂

​@@gotitdoneno I'm actually serious. Your video has really cleared things up for me. When I first saw that hole I couldn't sleep that night. I kept wondering who in the world had gone out of their way to take the dipstick out and not bother putting it back. I was very upset.

@@KG-ly5fu ah… so you were not lucky to find the plug just sitting in the side as it happened to many people. You actually lost that plug and had to buy a new one.

Have you cleaned the rubber vent?

@@gotitdone yes it doesn’t work. I use duct tape works good

@@mainaunt4447 then what happened is that the ATF plug is not snug anymore. I would recommend to change it with a new one (check the description of the video) but if duct tape worked and you are happy.. go for it 😂

@@gotitdone 🤣duct taped better

Car sucks because of a plug falling out?😂

No

Mine didn’t pop out but Susan want to run the chance and replaced it 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 was 20.24 mm.

That happened to me. I didn’t know if I lost too much fluid so I checked the transmission fluid level as soon as I discovered this. If I remember right, I had to put around 6 ounces.
