Sorry to ask, I've ran searches here and elsewhere for days now. Have 4 quarts of official Honda fluid, know where drain is, but despite being under car and feeling around a bunch, I cannot locate fill port.
All I need is picture or diagram or description of fill port. I'm guessing large bolt on side of CVT is the sight hole or whatever you call it, and you fill through mystery invisible, or at least hard to find, fill port until HCF-2 trickles out that sight hole?
Other than the obvious drain plug to poke a 3/8 ratchet into, no fill port or sight hole bolt are marked. Pretty obvious Honda doesn't want you to figure CVT fluid changes out. My car at 16K, I'd like to start the CVT fluid drain/refill about every 15k, of 3.6 quarts, as I've read. I might be obsessive, but that's ok, it's my money I'm throwing away. Please where is fill port and side sight hole?
Thanks old Harold.

 

I can barely see the cvt filler cap underneath the air filter assembly. It has a little hook on the top of it. You'll have to remove the assembly to get at it. Shouldn't be too hard.

 

Old Harold, Why would you want to? The CVT does not require service until the 3 service code shows. Mine did not show until 53,000 at which time I did the service myself in 30 minutes.
