Nice, that's way better than the little OEM CVT trans vent cap.

Was your CVT trans fill plug popping out?

 

No. I heard about the situation after I bought my 22 FWD ln March last year and came up with that plan shortly thereafter. It seems those transmissions need a little more venting. 14 months later and running great, but I only have 15k miles on it. Great little car.

 

Hey. New user here and glad i found this forum.

Have a 2016 hrv with around 71000 miles. Found that fill plug just laying next to the transmisson hole like everyone's been saying in past post..

I cleaned the breather cap. But now should i fill the hole with some tran fluid?

I recently financed this car. Love the way it drives.. But I'm not even sure when's the last time transmisson fluid been changed..

 

So I have a question…should I top up the transmission fluid if the plug popped off and there was noticeable fluid on the ground? I suspect I was driving 3-4 days before I noticed it due to rain. I really don’t want to replace the entire transmission fluid but I don’t want to overfill and hurt the vehicle.

 

There is only 1 way to check the level of the fluid in the CVT transmission on the 1st Gen HRV.

Make sure the vehicle is level, remove the fluid level check plug.
If no fluid comes out, stick your finger in to determine the level and color of the fluid.

If the fluid is too low, add fluid to the fluid fill plug on top until fluid comes out of the fluid level check hole.

 

Fluid should be checked cold too, engine off - and i would run through the gears for a few seconds prior to checking if you can ( if it sat over night etc)
there should be a label near the drain plug that indicated which type of fluid !

 

 

Because of the TSB mentioned, I make it a point to clean out the CVT vent every oil change!

 

thank you for your response. I took my car to another dealer last week. When I got there, the vent plug had popped off, instead of the fill plug. My trip to the dealer was 30 minutes at freeway speed, and the smell was worse than before.

They said the problem was caused by gunk on the plugs. To correct the problem, they are servicing the transmission, including changing the fluid and replacing both plugs. I think the original dealer service department should have cleaned the plugs, but apparently not.

To avoid the issue from happening again, check the vent plug and clear out the clog regularly, a very simple process.

 

Had my CVT fill plug pop off sometime in the last few days (checked every weekend, along with vent plug). Vent plug dry and clear. CVT was serviced by dealer 2k miles ago. I have OBDII monitor showing CVT Temps, which were always in the normal range (205*F and under).
This car's CVT is a real head scratcher.
