I had Honda change it after 75.000 km and 2½ year. thats was the service indicator

thanks for reply I was thinking that all the initial wear would happen in the first couple of thousand miles and any loose debris could be flushed out by a change of fluid just thinking long term it might be a good idea or maybe its a waste of time

I get my Jazz Hybrid changed every 25,000 miles as per service requirements. My Jazz is 3 years and a month old, and is due its FIFTH CVT fluid change in the next few weeks. :) Honda main dealers charge £70 for the fluid change.

I am sure that if Honda thought that the CVT fluid needed changing that quick they would include it in the service schedule, After all, they would make money out of it.

Getting back to the original question, I believe its a straightforward drain and refill, but I think its a case of the fluid deteriates rather than gets contaminated with debris. The car does feel smoother once the fluid has been changed, especially when moving away from stationary.

I was just really trying to be extra careful by changing it myself after a couple of thousand miles but its probably not really needed

So far it seems no one changes their own CVT fluid? Is it difficult to do DIY? Presumed it was as easy as an engine oil change but can't see any topic on doing it oneself. Mk1 and 2 Jazz

Trust me, they do. It's just damn difficult holding a camera when you've oil all over your gloves! (Then finding the time to write and post it all up)

This is for a GD Jazz, but it'll be similar for a GE.

Get some CVT-F x2. Case holds 5.4l and only 3.2l comes out on a drain, so change is done twice to flush.

The drain plug is definitely NOT a 10mm square, but a 9.5mm or 3/8" one.

Get the driving wheels off the ground and run it all selector positions to slosh it all around. Go out and re-set the clutch calibration. Rinse and repeat.

That's more or less it.

Can you please explain how to  re-set the clutch calibration

I would also like to know how to reset the clutch as I'm thinking about changing the oil I'm my jazz cvt box.

Post by: Eddie Honda on January 24, 2016, 01:06:47 AM
Find an empty road. Take the car up to 40mph with nothing electrical on. Then turn the dipped beam on and let the car coast to 20mph.

Forget about trying to short pins 4 and 9 on the DTC socket on a UK model, pin four isn't even wired up so will do nothing.

How much is the oil from Honda just out of interest?
Title: Re: Cvt fluid change
Post by: Eddie Honda on January 30, 2016, 01:25:58 AM
I expect 4L to be approx £40 UK. It's approx €50 in Ireland.
Title: Re: Cvt fluid change
Post by: olduser1 on January 30, 2016, 11:22:01 AM
a search Bay can often find 4l going for less.

With the caveat that it'll be a private sale of someone else's unused surplus. (sold car, didn't use it, etc.)

Post by: tetskoma on April 09, 2017, 10:33:15 AM
Just want to say a big 'Thank you' to this post. I managed to change the fluid on my 2004 1.4 SE by myself yesterday. This totally cured the funny vibration when the vehicle start moving. I know this will come back some point, but I am not scared of this anymore as I can fix it by myself.

Bought two genuine HONDA 4L CVT fluids on ebay (cost me about £80). I bought a washer (about£1 from Honda), but didn't use it as the old one looked ok.

For the safety, I shouldn't have done this but just used pump jack (ie no axle stands) as I didn't really have to go under the car (just my arms once I recognised the drain bolt). I found a tip to drain out the fluid more - jack up the right hand side of the car when it stop dripping on flat, which help the drain-out extra 100-200ml.

Follow the instruction as explained here (shifting between gears, holding up to 3000rpm etc), drained the fluid out again after waiting for 1 hour or so (someone said 'wait at least 20mins', but please wait more as long as you can. If this is too short, it won't cure the problem). It takes time, so be patient.

I changed the engine oil/filter/air filter/cabin filter/spark plug while waiting 2nd drain out. Now the car runs wonderfully. I didn't know the car is so powerful with full throttle, couldn't do before because of the vibration. I took me 4-5 hours in total, but it wan't too difficult and it is definitely DIYable if you have the right tools.
The costs in total were about £120 (inc oil and filter etc). For almost like a full service, it is not bad if you have spare time to do it yourself.

I got so much used to the vibration since I bought the car a few month ago, so I feel rather strange without any noises or vibration :) I would like to put a new aftermarket stereo next. Thanks.

Good to learn you were able to improve your Jazz & complete a thorough service.
As regards a change of stereo, I thought about it our one of our older Jazz models but ended up changing the speakers fr & Rr instead - no dash issues.

Please tell me how better to drain old CVT fluid, should I warm the engine or drain the cold oil?
 
Title: Re: Cvt fluid change
Post by: VicW on August 15, 2017, 03:34:58 PM
  I suggest that it is better to drain warm oil than cold as it flows more freely and hence carries more debris with it. If you are doing a double fluid change, ie a flush, then the second oil change will be cold.
Don't just warm the engine before you change the oil as this will not warm up the gearbox oil, take the car for a drive and use all the gearbox functions, 'D', 'S' and 'R', to get the oil thoroughly warm. You can of course put it all back together to warm up the second oil change if you are doing two.

Vic.

Post by: Nils on August 15, 2017, 04:15:00 PM
Thank you for your detail answer! I Is there some information about when just change CVT oil and when to make a double fluid change? 
If I need double fluid change may I do second change later on? (I have only 4 liters of CVT oil now)
Title: Re: Cvt fluid change
Post by: TG on August 15, 2017, 05:46:07 PM
On the official service schedule it is now replace every 2 years, but I see no harm on waiting until you start to feel the judder if you are doing the maintenance yourself.  There would also be no harm in waiting a week between 1st and 2nd fill, a luxury that a garage does not have.

I think there's benefit in using the vehicle for a week or two before doing the second flush: I recall that the discussion about fixing the clutch judder problem included explanation about giving the gearbox some hard work so that the clean fluid would pick up more of the accumulated muck before being drained out. Filling and then immediately emptying the fluid won't be as beneficial.
Title: Re: Cvt fluid change
Post by: Nils on August 16, 2017, 09:13:10 PM
Thank you for your advices!
I have changed the oil and vibration during the start disappeared. Should I change CVT oil for the second time soon, or I can leave this oil for 2 years or till the next vibration? I guess It was first change of CVT oil for 2006  jazz with 55000 km. Oil was moderately dark but not black.

Hi Eddie, thanks for all the info. so I have a GE6 Jap model Fit, is there any other way to reset the cvt ? short pin 4-9? where did you get this info have you got a service manual?

thanks again!

Post by: Eddie Honda on September 23, 2017, 12:53:15 PM
I've got a service manual somewhere, but I don't run Windows much - think it may be on the slow laptop.

Pin 4 and 9 depends on market. On both my UK market cars pin 4 isn't connected to anything, so shorting will do nothing.

Excellent write up!

I've just taken delivery of a GD3 with an uncertain service history so I thought I'd tackle this along with a standard oil, plugs and filters chance.
