Is the PowerShift gearbox reliable?

Ford PowerShift covers two different dual-clutch gearboxes: the dry-clutch DPS6, fitted to the Fiesta, Focus, B-MAX, EcoSport and C-MAX; and the oil-bath 6DCT450, fitted to higher-torque diesels in the Focus, Kuga, Mondeo, S-MAX and Galaxy. The DPS6 has racked up thousands of complaints about juddering and slipping, with a US court settlement in 2020; the 6DCT450 is more robust, but needs its oil changed every 50,000-60,000 km to avoid wearing out the clutch.[1][2][3]

Is the ZF 8HP gearbox reliable?

The ZF 8HP is an 8-speed torque-converter automatic gearbox, launched in 2008 in the BMW 7 Series and later adopted by BMW, Audi ('tiptronic'), Jaguar, Land Rover, Alfa Romeo and Jeep. It has a reputation for being reliable, although it accumulates jerking that sometimes calls for reprogramming the control unit, occasional mechatronic failures and leaks from the sump gaskets; the oil is sold as 'lifetime', but several garages advise changing it earlier.[4][5][6][7][8]
