Problem: CVT Fill Plug Popping Out (10th Generation Honda Civic)

If you own a 10th generation Civic model, you might have encountered the problem of your CVT fill plug popping out. The issue could arise due to pressure buildup or a clogged vent. The problem is frustrating and can lead to further transmission issues if not resolved in time.

Solution: Check the Trans Vent Tube Cap and Clean the Vent

One of the reasons for the CVT fill plug popping out is a clogged vent tube cap. Check if the trans vent tube cap has become plugged and clean it. You can find a black plastic cap on top of the transmission for the vent. Clean it and ensure it is not clogged.

You can also face the vent at a 2 o’clock position rather than facing it at 6 or toward the radiator.

If the plug still pops out, you can try securing it with a small tie wrap through the plug and the vent cap. However, if this doesn’t fix the issue, you may need to check if the plug has O rings to keep it snug. You can also check the Honda parts site for part number changes to see if improvements have been made.

It is essential to fix the problem immediately to avoid further transmission issues. If you continue to face the problem, consult a professional mechanic to check and diagnose the issue correctly. Keep your vent clean and unclogged to prevent further issues in the future.

It is worth noting that we are talking about the 10th generation Civic model. However, if you have a 9th gen car, the design might be different, and you may need to seek other solutions.
