Hard Shifting under Acceleration

[A8 Doc]

The automatic transmission should always be silky smooth. Always make sure the fluid is changed.

If the transmission is still not effortlessly smooth your brake pedal switch might be the cause. They have been known to fail and give a bad signal to the gearbox ecu. This can cause the gearbox to think the car is braking and cause the car to think something is happenning, that actually isn't.

See 'Common Faults' for changing the pedal switch.

In addition early D3's had very old software in the transmission ECU. Audi can update this and it will take 1.5~ hours.
