2.1 Information for the automatic gearbox
09G
Gearbox
The automatic 6 speed gearbox 09G is equipped with 6 hydraul‐
ically controlled forward gears. When the torque converter lockup
clutch is closed, the 2nd, 3rd, 4th, 5th and 6th forward gears be‐
come mechanically driven gears by bypassing the converter slip.
Torque converter
The torque converter is equipped with a torque converter lockup
clutch. The closing of the torque converter lockup clutch is load
and speed sensitive, and particularly low in vibrations, and without
the converter slip the direct gear clutch drives the 2nd, 3rd, 4th,
5th and 6th forward gears mechanically.
ATF
The ATF is filled for life. The ATF need not be changed within the
scope of servicing.
The ATF oil filling is for the planetary gear and final drive together.

♦ Only ATF available as spare part should be used in the auto‐
matic gearbox 09G. Other oils can lead to functional problems
or to failure of the gearbox.
♦ ATF Part No. ⇒ Electronic Catalogue of Original Parts .
Automatic gearbox control unit - J217-
The gear-change point is determined automatically, according to
driving conditions and road resistance.
Advantages:
♦ Fuel-efficient gearshift
♦ maximum engine power output continuously available
♦ gear-change points are adapted to suit particular road condi‐
tions
♦ gear-change points changed as required
Gear-change points change on upward and downward gradients
On upward or downward gradients, gear-changes are selected
automatically by additional gear-change mapping, according to
accelerator position and driving speed.
♦ On steep gradients, gear-change mapping is adapted to en‐
gine power output
♦ On steep gradients, gear-change mapping is adapted to the
braking effect of the engine
♦ By directly selecting a gear via the Tiptronic, e.g. for a slope
during trailer operation, the motor braking effect is also fully
used.
