That doesn't say they checked the gearbox box oil.

I'd suggest taking it back. Get them to confirm the oil level and to check the gearbox diagnostics.

Symptoms suggest low gearbox oil pressure. Could be failing seals or low oil (it then gets air bubbles in there which affects the pressure). An oil change could help.

Search AlexGS for some informed advice on preventative maintenance. Prevention is better than cure and all that.

I'd ignore someone who admitted continuing to drive with a known gearbox fault and then moans about the cost of replacing it.

That's what this is Mr. Russy. A known gearbox fault that can be only fixed for 1200 GBP. So yes she should check oil level, but there is always a reason why oil level is low. Fixing anything less is not fixing the problem correctly, which is why Fiat generally replaces the whole unit instead of certain parts (that's what the Fiat main dealer tech told me).
It is not normal, its probably why Fiat make it so difficult to check the oil in the first place, as in the car must be jacked up to see it from below the bottom of the car!

Re: The one and only Dualogic failure thread

I had no idea the part cost so much

I will book it into the garage who serviced it and get them to check it out. After that I really don't know. I think I paid top money for the car as it was hard to find an auto, then I paid out a few hundred for front and rear sensors as I am used to having those on our Mercedes, now of course I realise a car as small as a 500 really only needs the rear ones, if that.

In Greece generally you reverse until you hit the car behind = )

A friend told me never to get an auto in a small, unsophisticated car. It seems he was right.

Re: The one and only Dualogic failure thread

I've had a few smaller auto cars and never had a problem, Peugeot 206, Mercedes A Class, VW Golf V5, also have a friend who has an auto Mini, none of them have been a problem. In fact one of my friends has a 10yr old Fiat Panda with what seems to be a similar problem as mine, like mine it just plays up when she is doing a maneoveure that requires reversing and it's been doing that for years and never got any worse. If only I felt comfortable driving a manual, but I don't

Problem is the Fiat Dualogic is not a 'real' automatic. It's a hydroelectrical manual. I am hoping the next generation 500 will not have this gearbox anymore, it will have a dual clutch automatic like most new automatic cars being sold these day.

The Dualogic is a very old technology (1995 released).

Re: The one and only Dualogic failure thread

See that terminology means nothing to me

I know our Mercedes has a tiptronic gearbox and I thought it would be a similar thing with the dualogic box, guess I was wrong.

It IS similar.
basicaĺly its a Manual gearbox- with irs own oil- , but instead of a clutch pedal..it uses sensors and special oil..all driven by a computer.

So..get the garage to check:
1 : the level of oil in the gearbox
2: the level of fluid in the duologic reservoir

IF The duologic fluid level is low..then get it filled up..and purged of air and recalibrated

This will get it working perfectly

Re: Fiat 500c 1.4 petrol Duologic Transmission Failure - Australia

I do have an 2010 Punto with Dualogic. I have changed this parts already 2 years ago.
Now I have the same problem again.

yes but if the oil is low there is something wrong with the system.

did you replace the whole actuator unit? because any other fix is temporary basically. that's what happened to me, replaced bits and pieces but the problem kept on coming back until i changed the whole unit at once!

agreed,
but it's quite possible it's a VERY minor leak,
but the MainDealer's "service history" doesn't mean they've ever checked the levels..

Yes. Dealer charged me $2480.00 for this. Car was like 4 month at the garage.
I went to check right now. The Oil reservoir is half filled. Seems that it has a minor leakage too.
