Does anyone have a link to a video and/or instructions on how to change the transmission fluid in a 2017 Honda Fit? I also need to find out what type of oil it takes and the size and quantity of crush washers needed. Thanks!

@Jazu, thanks for the info. Is this something an owner can do?

In looking at the YouTube videos online, it looks very similar to how I replace my 2012 Honda CR-V rear differential fluid. Also, aside from a possible torque wrench, are any special tools required? In the YouTube video I watched the author is using a funnel with a long tube to reach the CVT fill plug.

Thanks again for your help.

 

You should do it yourself. The hardest part of the CVT fluid change out is reaching the fill hole, which requires a flexible tube and a funnel. I was lazy and had the Honda Dealer do it for me at 50K miles. The quote was $89.95, but with the HIDDEN added "shop charge" of $15.25 misc the total cost came out to be $108.54. It was a rip off that I considered a lesson learned. Yea, the charge includes the customer lounge with a TV, chairs, coffee, water, snack, etc. But, I never took advantage of them. You can buy the recommended Honda transmission fluid, HCF-2 for about $9/quart. These days, there are a lot of maintenance videos in the internet. Some are well done and some are really bad. At least, the producers were informative. Thanking them!

 

Thanks! I'll give it shot.

 

Does anyone know the hole size for the transmission fluid fill hole? I'm looking for a funnel with a tube to make installing the CVT oil a little easier. After looking at various automotive products, most of which were cheap, I found this. The only problem is the tube is fairly large at 1" in diameter.

 

Actually, one of these might be better. Do you think one of these will work, given the placement of the fill plug?

 

Yes- there's no other way to pump up to the case other than one that is gravity fed (another Plews product). In the case of the "sealed" transmission - you'll never get a gravity fed valve with a long-enough transfer tube to pump from a higher position.

I was going to recommend the same - after using the Plews products for many MT, Diff, and ATF fluid changes. Always buy one more than you need (to have one on hand at all times) or clean one up by letting it drip dry (do not use detergent and water - you'll never get it out). I've had to refill a leaking case on off-road machines after damage and used a spare I had in my tool board.

 

here’s how I did it. I removed the air box, it made filling a million times easier.

 

Wow! That's a whole lot easier. So to remove the airbox all I need is a 10mm swivel socket? Will this work?
Thanks!

 

Yes that will work or if you want to get a better bang for your buck harbor freight sells a 3 pack with 1/4, 3/8, and 1/2 swivels you use with regular sockets.

Mike, I followed your instructions and I was able to successfully change my son's transmission oil, so thank you.

The ONLY problem I had was I removed both of the small hoses coming from the metal piece on top of the engine and quickly discovered that one of them was filled with antifreeze. So, for anyone following these instructions, DO NOT remove the small hose going underneath of the intake valve. Also, in my particular case, I did not need to use a swivel socket, so that saved me an additional $12.75.

 

Don't omit the step where you cycle the shift lever then recheck the fluid level. Mine took a considerable top-off amount. Maybe 1/3 to 1/2 quart.
Did I miss something? Which crush washers did you end up getting? I could only find one size, so I ended up reusing one of the washers - I don't remember which one.

 

Hmm. I did cycle through the gears, but I didn't check the fluid levels because it's a royal pain in the butt just to access the CVT. How were you able to check the fluid levels without a dipstick? As far as the crush washer, I purchased one from my local Honda dealer. The price was a ridiculous $3.15 and that was discounted.

 

First I drained the fluid. Then I refilled the tranny through the side hole using an 18" piece of 1/2" dia tubing and a dollar store funnel. Then I replaced the side hole plug. Then I started the car and cycled through the gears.
Then I removed the side hole plug and added fluid until it dribbled out. (This is where it took another 1/3 to 1/2 quart.)
Then I replaced the side hole plug and I was done.

 

Just changed the CVT fluid yesterday at 30K Bought 4 qt on ebay $45 shipped with new washer.

The oil comes out fast as the viscosity is low. Drain pan should touch tire.

To fill I made a L out of some 5/8 copper tubing. Mainly because I have it and it works. I bent the L and put a transmission funnel into the top of the tubing. I did't measure the hole, but found I could not stick my index finger inside to check the fluid level, had to use pinky finger.

Took a tad less than 3.5 qt before it flowed out the filler hole. So slow down at 3.25 qt or you will have a mess.

Notes: Before draining the fluid level, I tried to check the level, but was unable to because of internal components could not get my pinky in there.
I put all 4 tires on some 4x4 blocks to get access to remove the plastic access cover that covers the bottom of the engine area.
Tools: 17mm fill plug, 3/8 breaker bar drain plug.
CVT holds 8 qt Roughly 3.5 qt drain out of the unit.
Buy 4 qt to do an oil change.

 

Does the third generation Fit have a transmission filter that needs to be changed? I know the second generation has an external filter but I'm not sure about the third gen.

Thanks

 

IDK - but all past AT cars I've worked on have a transmission fluid filter or "bolt catcher" screen of some sort that can get clogged..

 

also you can create a splash guard from a milk jug to duct tape or hold around the filler hole when dropping the bolt - I made one for draining the RX8 coolant from the block.
