A “transaxle” is a combined gearbox and final drive unit and is what’s fitted to front wheel drive vehicles (there are a very few where there is a rear mounted transaxle but it’s rare)
Very few European vans/motorhomes were ever fitted with “proper” automatic gearboxes, they cost a fair bit more than manuals so fleet operators were not interested in them, so manufacturers didn’t fit ‘em.
Having done a bit of research I now know that vans were made with the transmission option you mention, I've never actually seen one (not that, that is really relevant though).
I've not managed to find any meaningful information on it just a couple of references on the Fiat forum.
Sorry I've not been much help.
I'm a bit out of my depth with this one!
I wasn't aware that they ever used a true auto box with torque converter which is what the box (ZF4-HP20) you quote is.
You also mention that yours has " sequential manual shift", which doesn't sound like a true auto box.
The oil you drained out, what does it look, smell like? Is it red colour and very thin almost watery, or is it slightly thicker than engine oil and smells a bit like cats pee?
A transaxle is simply the term for a combined gearbox and differential unit and unless a four wheel drive always front wheel drive.
To go back to your problem of splitting your CV joint, normally you need to turn the outer part as far as you can and then with a twisting pulling motion the inner race will come out, then remove the circlip pull off the bearing carrier and change the boot.
Ok ... I now have to stop and recheck.
Note....My VAN is the auto transmission. ( I could see how people could be getting fill levels wrong)
My manual says 2.7L with Tutela Matryx for the Transaxle.
I was thinking that was the rear axle and not the gearbox?
But the rear axle sounds wrong...
Wow...this transaxle looks to be connected to the gearbox?
It sounds like there are two different fluids here...with different volumes!
The manual does mention two different fluids.
My manual says 8.2L for the auto gearbox.
But I will measure what comes out. If there is a dipstick, I will use it also. I expect around 2.5-3L? (note. this is not in the Fiat owners manual that I have or in Fiat eLearn that I have.)
I see said the blind man to his deaf wife!

Australia. Gday mate!
It is the RH drive version.
I do have a 2006 Ducato 2.8 JTD with auto transmission.
Good point. I did assume he was tallking Autotrans like mine.
When I read the OP post, it sounded similar to my auto transmission.
eg. the location of the ZF auto transmission located passenger side of engine bay.
Mine is the auto with sequential manual shift.
I think this was the forerunner to the 6 speed Comformatic gearbox?
Think I have the ZF4-HP20 auto gearbox.
The volume of ATF fluid says 8.3l in my fiat owners manual.
I got a ZF4-HP20 auto trans manual and it says Up to 3l drain of ATF fluid.
Hence the 2.5-2.7 OP mentioned sounded about right.
I cannot see the actual ZF gearbox code yet as it is obscured in the engine bay by the air filter box and various pipes from the intake.
But his comments...sounded same as my Maxi VAN.
This has all arisen from me having to replace a split rh side CV boot.
I have been avoiding pulling the whole right axle...as it meant a ATF oil change approx 30K early!
Was trying to just do the RH drive shaft/axle and leave the intermediate axle in the auto gearbox. ( thus delaying the ATF job until it is really needed)
Of course...we have bushfires all around Australia , hasn't rained in 10 months and where does it decide to bloody rain just when I have half the van apart?....outside! lol
I have been stuck .... separating the intermediate axle from the rh axle as it won't separate out of the cup.
Cannot work out why?
I followed Fiat eLearn manual ... but it seems to fall short .... the service guide I have.
Anyway, Are you sure OP was not talking about the Auto transmission model?
It does sound similar/same as mine.
I will remove my airbox as i need to confirm my Auto Transmission model .... I need to anyway if i am ever going to do an ATF oil change.
I cannot see things like the auto dipstick.
Cannot see the Breather plug others refer to.
I need to remove the items OP Tiffy said to see my Auto tranny better.
I do spy a blue knob/cap on the top about the size of a £1 coin . Hoping that is a modified dipstick? Unsure at this stage as that is not in the ZF manual either.
It's a magical mystery tour it seems!
I certainly need to find out.
I cannot really put it off any longer. ...in case it really decides to really rain here.
If anyone has any other info on this gearbox, it would be great!
This is a VERY technical vehicle...for a van!
They must drive their vans very fast in Italy! lol
Geoff, don't know if OP is still around his post is from 2010.
I have a FIAT 2.8Jtd, same engine.
"Most people report that Fiat stipulates 2 Ltrs. of oil, 2.7 Lrts. is widely recommended to ensure lubrication of the fifth gear cogs as this was a common point of failure on the 2.8 JTD models.
My vehicle handbook actually states 2.7 Ltrs. for transmission."
This is indeed a good idea. Additionaly I have seen advice to not select 5th gear until the gearbox oil is warm to assist the splash lubrication of 5th, so I do not select it before the engine is up to working temperature.
Also having a re-mapped engine I keep the revs in 5th to 2100rpm or more, to avoid strain on the drive train including the clutch. It is early days so far, as engine has done only 53,000 miles, mostly on M/Ways, Autobahns, but I am trying to look after all the running gear.
Peter that article is referring to a manual gearbox.
Where are you in the world? and where did your van originate from??? (country)
Yes....I have been searching for such an article.
Funny...as I havnt been able to find any other post on this for our model vehicle!
Perhaps I need to use the search function more.
I am still wet behind the ears with this van! a ducato newbie...
which is rapidly changing as i attempt to change the CV joint boot.
Turns out I have to pull the right axles out...which means drain the auto trans and refill.
I do not have that Tutela available. But I have an equivalent ATF....the specs look correct.
Never owned an auto trans before so this step is done with trepidation and lots of research first.
I havn't rushed into this job!
