Fiat 9 speed automatic

Similar problem here. 2021 Fiat campervan with 9 speed automatic 140 multijet. Nice gearbox but on a dual carriageway I pressed the mode button to change from power to normal as I was trying to see what difference the gearbox modes make. After pressing from sport to normal I pressed the throttle fully down to kick down. The gearbox dropped into neutral and I lost drive power. Although I was still in Drive the power was not being delivered to the drive wheels and the revs were unresponsive. Pusing up and down on the throttle pedal did little to affect the revs.

I pulled over. Turned everything off and restarted. Problem was gone and everything back to normal.

My concern is I have 2 months left on warranty and I'm not sure what to do about it? I havn't been able to replicate problem so if I take it to a dealer theres nothing to show them.... 

I get somethines there are glitches. I had a Discovery one that went into limp mode. Trun on and off and it ran again for years and never repeated the problem. I am curious though to see if anyone else has had this issue with the ducato 9 speed automatic box?

We have ordered a Wildax with the auto box which I’m told is a Mercedes unit. Our local dealer has only ordered auto versions as he says the 9 speed box is so good. Hopefully we won’t have the problems mentioned above.

As I mentioned on page 1 the same 9 speed box is in my car, and behaves impeccably. Almost certain it is down to the software design by differing motor vehicle manufacturers, maybe vehicle weight plays a big part in how the software is written and behaves.
