We have a 2022 Fiat Ducato based motorhome with the superb 9 speed automatic gearbox. I have found one anomaly, and wonder if anyone else has found the same. Stopped at for example traffic lights, gearbox in Drive with the annoying start/stop function disengaged, and foot on footbrake, the gearbox drops into a sort of neutral. When lights change, foot off the brake, it takes a couple of seconds to re-engage the drive, and it does so with a mild “clonk”. If you accelerate before it re-engages, there’s quite a big “thump” as in engages again. I guess there’s not too many of these new boxes out there, but has anyone come across this, and is it considered normal for this gearbox? Thanks

We had 2020 model with this gearbox and now have a 2021 and have not encountered this issue with either van. Mind you, I generally put it in neutral and use the handbrake if stopped for more than a few seconds. And, yes, I turn the flaming stop/start off too!

I suggest you get it checked under warranty.

We used to have an automatic Astra that did similar ....

And yes ... I know an Astra is not Fiat nor 9 speed ... if you gave it a second or so to get back into Drive it was OK.

Is the Fiat slushbox or automated manual? 🤔

No, it’s the latest 9 speed auto, not the old 6 speed semi auto.

It’s a slush box, ED.

D'you think it could be connected with Nicho leaving it in D?

I very much doubt it. I & most people tend to leave an auto in D .... and cars with some kind of 'HOLD' encourages it.

It’s still doing it - 850 miles on the clock now. I have learned to live with it and on most journeys, the circumstances only arise two or three times. I will try putting the handbrake on and releasing the footbrake on the way home. Drove 130 miles yesterday, and once on the move it behaves impeccably. I will talk to a Fiat dealer, but in a couple of weeks we are off to Devon and Cornwall, so it can wait until we return. Any parts from Italy could take weeks, so I may leave it until the end of the season. Fiat U.K. say it will not cause problems.

We have a 2021 Fiat Ducato and have had experienced exactly the same problem, on 2 different occasions we have taken the Campervan to Fiat and they have said its a "Diagnostic" problem and reset the diagnostics, each time a red engine warning light has come on. At the time we can still drive the van but only in the manual mode, the automatic mode only seems to have one gear.

Each time the Van has been fine for a few weeks, now on this occasion the Fiat garage have said it needs a new Gearbox Control Unit, which is not available until 14th September.

I noted that you are still using your Motorhome and mention Fiat UK have said its ok to do so, will it not damage the engine?

Any help would be extremely appreciated as we are due to go to Spain on the 8th September!

OK so yours is a Motorhome and mine is a car, but both have the same ZF 9-HP German 'Slushbox', in use it is fantastic, smooth and responsive, and I can see no good reason for the behaviour yours is showing. Definitely something amiss.
