Hi Guys, first time posting. Was doing a CVT fluid change and instead of opening the drain plug first, I opened the "check" "overflow" plug first and immediately closed it.
Now when I went back to put new fluid, I ran out of fluid and it didn't overflow after I put the shifter in PRNSL.

I'm wondering if I could just warm up the car and shift thru PRNSL and fill it till it overflows? Seems like too much came out?

Thanks.

This is a 14 or newer CVT trans? Make sure you used Hondas HCF2 fluid! (for non-hybrid cars)


It will drain about a gallon if you let it dribble 5 minutes or so......but those will keep on draining as long as you leave the plug out.... If you left it draining long enough it might drain far more than 4 quarts out as it slowly empties the torque converter....

This is why I drain this trans fluid into a gallon jug, so I know how much comes out and how much to put back in



This is how it's supposed to be done !!
(The check plug is called a "spill hole" for good reason)

This is 2015 Honda Civic Coupe CVT.

My only concern is overfilling it but I don't think it's possible due to overflow "check" hole.

If you do it correctly it will be the correct level!

Ended up adding roughly half a quart to get it to overflow. Driving much better, feels quicker and in the proper gear. It had hesitation before. This is my GF car which has 63K on it which she bought brand new.
