It’s always worth contacting a carmaker’s customer service division in a case like this. I agree that 136,000km is far from a reasonable expected lifespan for a modern more vehicle of any sort. But exactly how Volkswagen Australia will view the matter will depend on the car’s service history and how it was used.

You might have some luck and perhaps financial assistance in getting the Amarok fixed, but VW could also point at the age of the vehicle and the fact that it’s way out of warranty. But, again, if you don’t ask, you’ll never know. Don’t bother pursuing this at a dealership level, either, go straight to head office.

You need to get this vehicle to a transmission specialist right away. There’s clearly something not right either mechanically or electronically with the gearbox, and continuing to drive it in its wounded state is a big chance to cause more damage than has already been done.

Any vibration in an automatic transmissions suggests either torque converter or internal problems. It may already be too late for your vehicle, and the damage may already be done. But the sooner you get to a specialist, the less expensive, permanent damage will be done.

They’re not any more or less expensive to maintain than the Mazda or Ford. A VW dealer will be more expensive than an independent mechanic, but there’s nothing to prevent a regular mechanic from servicing it.
