Is the Dualogic gearbox reliable?

The Dualogic is the automated manual gearbox that Fiat has fitted since 2003 to models such as the 500, Panda, Grande Punto/Punto, Doblò and Qubo, and that Lancia sells as D.F.N. on the Ypsilon. It has no systemic fault acknowledged by the manufacturer, but there are recurring testimonies of jerking on every gearchange, clutches that wear out early, and actuator faults that make the gearbox drop into neutral on its own while driving.[1][2][3]

Is the CVT Jatco JF011E gearbox reliable?

The Jatco JF011E CVT (Nissan’s Xtronic, Renault’s X-Tronic, Mitsubishi’s INVECS-III) has weak points well described by workshops and the technical press: wear of the pump and its valves, bearings that hum and, according to some sources, the belt and pulleys. Nissan fixed a possible belt slip in the first-generation Qashqai and X-Trail with software.[4][5][6][7]
