Mk1 CVT judder
« on: December 08, 2007, 09:11:33 PM »
1.4 DSI AUTO 04 PLATE ….when i stop at lights and take off again it goes for a second then kind of judders for about half a second then is okay….also when i take my foot off the acc pedal it seems to slow down quite a lot …IS THIS NORMAL ?

checked level of atf it seems fine but really light in colour almost like cooking oil? all my other autos have been a dark red colour ….any help please

Note by RichardA:
I have had confirmation from Honda (as of July 2012) that Honda offer a 7 year warranty on the CVT judder meaning that the repair is free of charge at a Honda dealer (in the UK at least).

Do not take your Jazz to a gearbox specialist without talking to your Honda dealer!

If you car is over 7 years you could still try your luck - they can only say no! :)

Hi Wetclio.
About the only things that you can check on the auto box is the level and quality of the fluid - as you have done this and all seems OK then your only option is a quick trip to your local auto box expert - they should check it out free for you…
Hesitation with auto transmissions is often caused by a slight misfire in the engine and is difficult to identify, so it is worth replacing the spark plugs if they are coming towards the end of their 25k mile lifespan, (there are 8 of them) also the famous EGR valve in earlier posts might give you similar symptoms.
Revving the engine in neutral might give the game away, but the engine is more likely to misfire under load conditions - so this would only be a guide.
Hope this helps.

went to an autobox specialist and he said he could feel the judder but all he said he could do is replace the ATF in the box….what worries me is the violent/quick slow down with my foot off the accelerator should it slow down this quick with this gearbox (i was thinking engine braking)inside the box …any help would be great ….many thanks

If the brakes are on to produce this effect they would be getting very hot after a short period - a kind MOT tester would easily be able to put it on the brake tester and see if they are binding… or you could try on a slight slope in neutral - it should roll easily.
It sounds like you didn’t find a particularly helpful gearbox specialist.
Though I don’t often recommend it - a dealer might be your only option to get a definitive answer …..

Interesting. I am experiencing a similar problem. 3 weeks after my Honda’s 50000 mile service (the so-called biggie), my 54 plate Jazz auto now conks out when idling. Basically, it conks out anything below around 1200 revs. It also judders a bit on acceleration and is acting very strange. I’ve read that this could be a few things on a number of forums but not specifically about a Jazz. My father says he reckons this has something to do with pipes leading in and out of the air filter coming loose but I’ve yet to check as the weather has been rather inclement. I’ll let you know how I get on. Anyone else got any ideas!?

If the atf has be changed and the judder has come back it could be a problem with the start clutch within the gear box. The same has happened to mine so i contacted my local dealer and they told me about the start clutch.Its off to be replaced next week. hope this helps. trev

In this weeks Honest John’s column in the D Telegraph a reader from NZ commented that CVT transmissions were failing around 60k

A quick check on the mtce schedule for Jazz CVT states change the fluid with ATF Z1 at
80,000 km (48,000 miles) or 5 years

A further search on Google shows Honda offered two oils see below

any suggestions , or better still anyone had the CVT fluid changed ?

Local Honda agent wanted £7.00 per litre for Z1 [ plus VAT }

Dealer’s all confirm the oil for the Jazz Auto is the ATF Z1

NB this has now changed see the latest posts

only use CVT oil in your jazz Auto - CVT
it all makes sense now !

CAREFUL!!!!

I’ve owned two CVT-7 Jazz’s and I can tell you right now without any shadow of a doubt ATF-Z1 is totally the wrong oil for your Jazz CVT.

The confusion is that in your owner’s manual it will say that ATF-Z1 should be used and may be Dextron III if ATF-Z1 is unavailable. However this is now incorrect.

Honda released a Worldwide product update (PDU) that informed all dealers, and service depots to use only Honda CVT-F (Honda part number (4 litres) 0826099904HE) in all CVT transmissions in Insight, Civic IMA, HRV, and JAZZ.

ATF-Z1 should only be used in conventional, i.e. non-CVT, automatic transmissions. It is highly likely that your dealer (in the UK) will not know this. The two Honda dealers I use did not know and I had a hard time convincing them until they find out about the HONDA product update notice!

If you call HONDA UK’s customer service line they will tell you that there is only one transmission oil suitable for the Jazz CVT-7 - Honda CVT-F. There is currently (March 2008) no oil produced by another manufacturer that Honda have qualified as being an equivallent to CVT-F.

If your dealer has replaced your CVT transmission oil with ATF-Z1 get it changed immediately! It will eventually damage your CVT transmission if used long term.

I know it is very difficult to tell a service manager his job but you HAVE to in the case of UK Honda Dealers with respect to the correct CVT transmission oil to use.

If you are having your transmission oil changed, explicitly say that you wish the transmission filled with CVT-F and NOT ATF-Z1 (or equivallent). Also since CVT-F comes in 4 litre bottles, ask to get the remainder (0.8 litres) so you can “use it top-up”. That way you know it’s correct.

If you’re thinking of buying a Jazz CVT-7 that has travelled more than 50K miles, check the colour of the transmission oil (yellow dipstick, front right-hand side). ATF-Z1 is a very red colour. CVT-F is a golden-yellow with a tinge of red.

Hope all this helps you fellow Jazz CVT-7 drivers!

Well I have a ‘07? model and I checked the manual and it clearly states ‘Use Honda CVT fluid’

No mention of ATF-Z1 or dexron III

CVT requires CVT fluid - SIMPLE

Hi, I had an issue with my CVT on my Jazz and the dealer has replaced the oil with the correct one as detailed by dunkv. I just checked the service worksheet and they used the new CVT-F oil. They said if it didn’t cure the judder from the transmission they would work with me to pin down Honda on a warranty claim. Hence I think my dealer knew all about this. It was Stratstone Honda in Bradford.

Lately my jazz has starting juddering when moving away from standing position.
Initially I thought tyres were slipping. But with new tyres all round still get the same.

As there’s no clutch on automatics I’m now wondering how bad this is going to be!, any one had similar problems?

Feeling a bit lonely here!.

Has no one any suggestions on what might be going on with an automatic which judders on power application from a standing start?.
