Title: CVT Fluid Change
Post by: Leo on January 08, 2017, 11:07:20 AM
My car is overdue for CVT fluid change. Is it difficult task that needs to be done with Honda dealer only or it can be done by local garage also?

It's not difficult with the right facilities, there is a drain plug and a refill point with dipstick.
You should only use the Honda fluid called I believe, CVT-F, and drain, refill, run the car selecting all the functions and then drain and refill again. You will need twice the amount of oil specified for the capacity of the gearbox.
Do a search on here, there is loads of info on CVT oil changing.

Honda main dealers charge £70 for CVT fluid change, if you go that route.

Hi,
Honda now recommend the oil change every two years,

A Honda dealer sells Honda fluid cheap on ebay.. excellent service..

CVT's require cvt fluid not atf fluid

ATF-DW1 is recommended for Honda automatic transmission models.

A CVT  is not like a 'normal' automatic transmission and requires the use of Honda CVT-F not an ATF.
I have queried this with my local Honda dealer and was told that the fluid for a CVT box is CVT-F and nothing else.
I have no idea what the subtle differences are between the two types but I do know what I would use and have used in the past.

For €1 / litre more than the ebay ad you have the right CVT fluid for your car.

Very quick and good service from Cox! I ordered our Jazz stuff from them as they have better prices than here in the Netherlands. ;)


edit: of course i bought MTF for our iShift. ;)

I'm not sure they change the oil completely for that price. It costs more than £70 to buy enough oil to fill the transmission. How on earth can they make money if they're doing it properly?

Honda CVT fluid in above post link is €38.40 for 4 litres! I think that's enough to change it twice.
Title: Re: CVT Fluid Change
Post by: Pumpkin on January 28, 2017, 01:26:33 PM
I think the capacity is 5.4L, though I may be wrong. I've definitely seen 5.4L quoted in another thread:

A drain only releases around 2.5 litres. capacity is double that..approx. 
Honda's schedule cannot be a full drain.. That requires drain once, refill 2.5litres. Drive 15 minutes. drain again. Refill. That is more like £150+ worth of work..

Honda may put a suction tube into transmission and draw all the fluid out that way. That is how you do it on a transmission with no drain plug.

Don't forget gearbox flush is different from gearbox oil change.  Flush £150;  Oil change £80 and check the magnetic plug for metallic debris

hi guys,

i bought a jazz 2005 (51,000 miles) recently, its last service history record was on 33,500 miles end-2016.

i've just done new, spark plugs, air filter, engine oil & filter.

i checked here and i'm getting confusfed in regards to the CVT Fluid Change -

would it been of done @ 33,500 miles service?

also when is the correct milage to do this CVT Fluid Change ?

thanks in advance for any help!
Title: Re: CVT Fluid Change
Post by: sparky Paul on August 24, 2019, 01:28:34 PM
As far as I know, it's now every 25,000 miles or two years, whichever is soonest. I believe it was originally 50,000/4 years, but this was found to be insufficient.

In theory, it should have been done several times. If in any doubt, I would change it and start from there.

thanks Paul,

can it be done DIY?

If so can you kindly point me to a CVT Fluid Change DIY thread if theres one, thanks!

Other threads will say it is essential to use only the correct HONDA fluid for your car.

Hi,

I realise this is an old thread, However I was wondering if anyone has changed their CVT fluid using a pump, as opposed to undoing the drain plug. Would that work?

I've used a pump for engine oil change, and it worked well, so thought I'd do the same with the CVT fluid. The pump manual says to only use it for engine oil (or Diesel) and not gearbox oil (as that is potentially thicker), I don't know yet how thick CVT fluid is , but from the dipstick, it seems fairly runny.

Although I have no shudder on startup, I do notice a bit of a lurch, under moderate acceleration, when moving off from a roundabout, or joining a motorway. I use S mode as a workaround for quick pickup, but thought it maybe a good idea, to change this as I don't know when it was last changed.

The oil is pretty thin, I doubt the pump will struggle to pull it out but I doubt it will be able to pull out the full approx 3L that a change entails. I tried pulling some out recently and it was a struggle to even get 500ml out with suction.

Gearboxes are complex and I doubt that the filler/dipstick hole gives you access to the lowest point like the sump plug does.

I could be wrong though and knowing where to place the suction pipe to access the fluid better may help.

Most gearbox oil now is no thicker than engine oil,  the days of the old 'gearbox treacle' are long gone due to churning losses and higher MPG ( especially when cold ) being incompatible... probably still pay to go for a drive to warm the oil up, as that makes quite a difference.  It may pay to compare the oil level on dipstick to the shoulder that sits on top of tube with the length of oil you get on the tube of your vacuum device when it is pushed down into gearbox,  that will give you an idea how far down the vacuum tube is going.

Happy to report that the pump out method worked with the CVT fluid. I was able to extract about 2.4 litres of cvt fluid. I noticed that the level on the dipstick was higher with the car sloping forward,( front wheels lower than rear wheels.) so pumped out with car in that position. Went for a short drive to check if the lurching under moderate acceleration was cured, it seems to have made a difference, as I now need to accelerate harder than I normally would to get it to happen, but it’s not completely gone. But again, This wasn’t a complete change of fluid , but will do for me for now, I’ll pump out and fill it again in a month or two to complete the ‘flush’. Hopefully that will cure it.

When you refill it again try adding Xado EX120 additive, coupled with an oil flush my jerkiness has been eliminated. For a small cost it is extra insurance.

Post by: DomnicZZ on September 20, 2020, 05:33:25 PM
Thanks, Yep, I did read about it, will consider it after my next oil change.  I’ve seen ads about it, but nice to have that validated by someone here whose actually done it. Thanks!

I've just done a CVT oil change and it is pretty straightforward. Took the advice and added the Xado 120 as well and it has immediately eliminated the judder it had.

Welcome. It is quite common for gearboxes (and other components) not to drop their entire contents when drained. There could be baffles inside the sump or an internal filter and/or oil pump that retains fluid. The main thing is that when you refill it, you let excess oil escape from the Fill/Level port so as not to overfill it.

It's actually just over 3 litres that drains out, it's because it's an automatic and oil remains in the operating parts of the gearbox, you can only drain all the oil if you open it up.

Please can someone tell me how much CVT oil to refill on a Jazz 2007. I am doing a flush because of the juddering problem and need to know hou much to refill. It seems to me that currently it is overfilled. Please also see photo of the dipstick. Please advise.

You need to get the service manual which is available via google or google how to check the CVT oil level because it's a bit of a process. Do not drive the vehicle until you've ensured the level is correct because you may cause expensive damage.
