ack in 2008 Dave Skora wrote
a series of articles introducing
the VW 09G 6-speed trans-
mission. That was before most shops
were likely to run into this unit, but at
ATRA we always like to keep the trans-
mission industry up to speed on the tech
that’s coming down the road.
Well, it’s been two years since
then, and these new transmissions are
starting to find their way into transmis-
sion shops all over the country. These
units are most commonly seen in the
04-08 New Beetle and the 05-08 Jetta
with various engine sizes.
In this edition of Fun with Figure 1: The fluid level is correct when it just runs out the stove pipe inside the pan.
Transmissions, we’ll look at a few
critical aspects of service for the 09G,
including fluid level inspection, valve
body service and rebuilding tips.
Oil Fill and Level Check
The only way to check the 09G oil
level accurately requires a scan tool to
determine the ATF temperature. When
it’s full, the oil will just drip over the
stovepipe in the oil pan when the oil
temperature is between 35ºC (95ºF)
and 45ºC (113ºF). You should replace
the seals on the fill plug and fill level
pipe plug whenever you check or drain
the oil.
To check the fluid level:
• Park the vehicle on level ground.
• Connect your scan tool to the vehi-
cle.
• Make sure the transmission fluid is
cold; below 35ºC (95ºF).
• Remove the fill level pipe plug.
• Start the engine.
• Watch the ATF temperature as the
transmission warms up. Figure 2: Always mark or take a picture of the harnesses connected to the solenoids
• The ATF should begin to drip out for easy reassembly.
