CVT Cooler
 

Anyone added a CVT cooler to the Fit 3 yet?
Where do you get the kit from? Or did you buy the parts and DIY?

Nobody?
People here have modded exhaust systems, intake systems Body kits, ICE systems etc........ and no one gave any thought to cooling the CVT fliud?

Its not one of those things thats often looked at unless you were towing for example, which if you are then you are asking for a CVT to fail. The other reason is if you live in a hot climate where the concern of the tranny fluid getting too hot was a problem. Plus adding a tranny cool takes away from the efficiency of the radiator and AC depending on what position its placed in.

You can various sizes on this site here in the states,but like I said, its one of those accessories that isn't really needed.

Have you measured the CVT to see if it's overheating or are you in search of a solution to a theorized problem?

The CVT in the gk has been around for 6-7 years and I haven't seen a reported case of the CVT failing. I'm at 76k+ and so far so good but I'm also not racing, just using it for normal commuting. I changed it the fluid around 50k according to the maintenance minder.

Well over here in forever summer Singapore, the CVT temp in my car can hit 101 degrees Celsius. The norm during driving ranges from 87 to 93 degrees Celsius. I drive in the city most of the time and prolonged exposure to such temperature can't be good for longevity of the CVT. I also find that once the CVT temp hits 91 degrees celsius and above, the car feels sluggish and there's an obvious power loss during driving.

Honda recommends changing the CVT fluid every 40,000km. My car's mileage is at 25,500km and after changing the CVT fluid, I can feel the car is actually smoother during driving. The difference is really as clear as nigh and day. That's what got me thinking about installing a CVT cooler.

And I just did it today. The temp held steady at 75 degrees Celsius and never exceeded 78 degrees Celsius. Power remains solid throughout and I'm happy with the mod.

The below photos shows the temp I'm experiencing at the end of some heavy City driving. 101 degrees celsius!!!!!

101 down to 77? wow, that is a huge improvement

Wow! Big difference.

Yep. That's why I'm very happy with the mod.
It's worth it over here at forever summer country.

How did you install it? and which kit did you buy?

The kit is available only locally here and i suspect they sourced the CVT adaptor from Taiwan. They wouldn't tell me

Today i tested the effectiveness of the Cooler again.

I did a 0 - 100km/h sprint and then drove the car at redline for about 2 mins at 2nd gear. Temp went up to a max of 86 degrees celsius.

I then went onto the highway and drove normally at 90 km/h home in D.

The temp went down to 79 degrees till i reached home

The above Just for info should anyone needs it.

That looks like a well made kit and the numbers definitely shows it made an improvement. If someone could source that kit into the US, I'm sure some other members would like to try it out.

BTW - what kind of diagnostics reader are you using?

Hi,

I'm using a Lifi gauge. Made in China but works well.

I used to have an Ultragauge but could not get the PID codes for the CVT temp readout.

Easily sourced here in the states. Couple different options too.

Good to know and thank you for the link. I don't tow, but may look into it. CVT seems to be doing fine on mine so not a huge priority for me.

Do you have it installed? Does it take that much additional CVT fluid?

Sorry but CVTs while they have their place, I think are garbage. I've been driving a manual since I was 16. Will make every effort to do so until my legs dont work anymore lol. A tranny cooler on a manual would be extremely difficult to implement since it lacks the input shaft pump the CVT does.

No worries. Used to drive stick shift only, but then bought a 4Runner where that wasn't an option. Bought the GK as a commuter car in DC Metro area and found the CVT got better gas mileage so that's what I went with. 4Runner got sold and I got a Odyssey for the wife instead.

When I want to flick through gears, I've got an SV650 for that these days :)

That adapter looks like the same one for the 2016+ Honda Civic coolers that are available. I can't seem to find one anywhere else. Do you think the cooler kit at this link will work? All the ones at etrailer don't have the cvt adapter.

Short answer is I think it would

The part number for the cvt "warmer" is different between the two vehicles but I think this may have to do with hose routing

This is the best I could do for comparison of the back side. The reddish area is the fit and the underlying grey is the civic part so it does look like the plate would work as all the bits that need to line up do. Since the O-rings are shared between vehicles we can be sure that the scaling is correct.

Here is an EBAY 2016 Cooler Kit that seems like it would work
https://www.ebay.com/itm/2016-Honda-....c100752.m1982
Another interesting note is that the Civics/HRVS/CRVs in other countries have OEM CVT coolers. I could not find an OEM foreign fit cooler plate. This part is for 2017,18,19 for sure

Great! Thanks for all the info @tyrtill. I'm going to get the ebay one you linked (looks like it's the same as the vivd racing one but cheaper). I'll let you know how goes.

Gave it a shot, and the answer is....NOPE! Does not fit. The screw holes don't line up.

Are they off just a tiny bit? That’s disappointing.

The bottom hole is off by quite a bit. If you look at the adapter in @JingJangJoe 's post, the bottom hole angles in the opposite direction of the one in the 2016+ Honda Civic kit. The top holes are only off by a little bit though.

That’s strange.
It almost looks like it would fit if the plate was flipped over.
I wonder if one of the parts pictures I had was mirrored before I downloaded it.

I found this, anyone have any experience dealing with this website?

Congrats on the successful installation. Would you mind sharing where you get the kit from and the connection route as well? I have the same problem with my CVT. Had to change fluids at 16,000km because it feels very sluggish although it's almost brand new. Car drives much smoother now which is what it's supposed to
