Reading the posts here I assume the FIAT dealers don't know / care about the Dualogic...

The Dualogic / Selespeed / Comfortmatic / F1 gearbox is a robotized manual gearbox. It needs regular and precise servicing. If not taken care properly of, it gets problematic. It has been installed across most of the FIAT makes (Alfa Romeo, FIAT, Lancia, Maserati) under different commercial names, but generally the system is the same. And has same problems...

It has 3 fluids. Including the DOT4 fluid, which is highly higroscopic, so it should be replaced every 2 to max 4 years to maintain its properties.

Here's the official FIAT diagnostic on the Dualogic. This one has been published for the AlfaRomeo, but as mentionned earlier, the system is the same, part localisation and minor things might differ. It contains instructions on fitting the new hydraulic unit:
