Is the VW 01M gearbox reliable?

The VW 01M is the 4-speed automatic gearbox that Volkswagen fitted from 1995 to 2005 in the Golf, the Bora, the New Beetle and, according to the sources, the first-generation Octavia, León and A3. Its documented faults are the wiring and speed sensors (emergency mode in third gear), wear of the valve body and the plastic speedometer gear.[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]
