General repair notes

To ensure flawless and successful gearbox repairs, the greatest
care and cleanliness as well as the use of good and proper tools
are essential. Obviously, the basic rules for safety also apply dur‐
ing repair work.
A number of generally valid instructions applicable for the various
repair procedures - which were formerly repeated a number of
times at numerous places in the workshop manual - are summar‐
ised here. They apply to this workshop manual.
1.3

Gearbox

The "6-speed automatic gearbox 09G" has six hydraulically ac‐
tuated forward gears. When the torque converter lock-up clutch
closes, 2nd, 3rd, 4th, 5th and 6th gears become mechanically
driven gears by eliminating torque converter slip.
1.4

Torque converter

The torque converter is equipped with a lock-up clutch. The lock-
up clutch locks up depending on load and speed. The 2nd, 3rd,
4th, 5th and 6th gears can be driven mechanically (without slip).
1.5

ATF

The ATF is filled for life. The ATF need not be changed during a
service.
Use only ATF which has been ordered as a part from the ⇒ Elec‐
tronic parts catalogue "ETKA" .
The ATF levels in the planetary gearbox and final drive are
checked and topped up together.
