Yep, you need to push the new fluid in by the drainplug. Here is what they say you need to do. VW G 055 540 A2 (latest VW-approved ATF for the 09G transmission)

Filling Procedure

The transmission is filled from the fill port using a hand pump.

Install the drain plug/overflow tube.
Pump ATF into the transmission until it begins to run back out.
Start the engine.
Hold the brake and shift:
P
R
N
D
Manual ranges
Back to Park
Pause 3–5 seconds in each gear.
Leave the engine idling.
Fluid Level Check

The critical part is checking the level at the correct fluid temperature.

ATF Temperature

35–45°C (95–113°F)

With:

Engine idling
Vehicle perfectly level
Transmission in Park

Remove the drain plug:

A thin stream that changes to a drip: Level is correct.
Nothing comes out: Add more fluid until it begins to drip.
A heavy stream continues: Allow it to drain until it becomes a slow drip, then reinstall the plug.


Check out the images (below). Let me know if you need anything else.
