My point was that I've had auto boxes in Audi, BMW, Mercedes, Nissan, Toyota, Vauxhall, Volkswagen, Porsche, Maserati, Saab, Fiat, Peugeot, Volvo, Rover, Honda, Dodge, Ford and I'm sure I've forgotten a few....Dated between 1987 - today. Variants from standard old slush boxes, to tip-tronic to CVT to current dual clutch fast shifting boxes...Can't say any has particular issues or is to be avoided.
My favourite of them all was the Nissan Murano with its CVT gearbox, so super smooth and fast...Based on that experience I can't but disagree with @un1eash regarding CVT, although I'm aware that Audi's implementation (or mating to engine/drivetrain?) seemed to have been flawed.
I think my least favourite was the Nissan Patrol but to be fair that was more its mating to an agricultural 4 cylinder 3.0 diesel opposed to the box itself. The combination of that one didn't work that well.
Currently I've got three auto boxes;
1. Tiptronic from 2004, done about 112K miles mated to a 3.0V6 with mechanical four wheel drive. I've had one issue just before Christmas, but that was that the electronics corroded over time and once desoldered and soldered and reprogrammed it is as smooth as ever again.
2. DSG from 2014, done about 40K miles mated to a 2.0 turbo with electronic four wheel drive. Super fast shifting thing from the VAG group. 7 speed and I love it. But does require a different driving style to make most of it.
3. 9G-Tronic from 2017, done about 40K, a 9 speed with hydrodynamic torque converter (i.e. uses fluid instead of a mechanical clutch) mapped with AMG software to a 3.0V6 twin turbo with primarily rear wheel drive. My least favourite as it is only superb when you really push the car...
Anyway my point being, all gearboxes can be different depending on the combination of the car, engine, drive train and software provided by who ever installs them. As such it is impossible to provide a generic answer that is based on facts.
I really wouldn't be concerned about any particular type, but try them out and see where you like it in combination with the car as that is the only thing that matters. For example last holiday I had a Fiesta with an auto, I hated it, but that wasn't the fault of the gearbox. It was the fault of the engine being too small. Same as with the replacement which was a Nissan Juke, again that 1.2 was no match for the CVT.
Anyway just my opinion, go try them for yourself! |
