GENERAL DESCRIPTION

The Mercedes 722.6 transmission made its first
debut in the United States in 1996. It is used behind 4,
6, 8 and 12 cylinder gasoline engines, as well as their
diesel engines. It is their first completely computer
controlled transmission and their first transmission
equipped with a converter clutch. This fully electronic
controlled five speed automatic transmission consists
of 3 compound planetary gear sets, 3 multiple disc
driving clutches, 3 multiple disc brake clutches and 2
free-wheel (sprag) clutches, with 5th gear being
overdrive. The three planetary gear sets provide the
five forward gear ratios and two ratios for reverse.
Changing gear ratios is fully automatic and is
accomplished on the Mercedes units with the use of
an Electronic Transmission Controller (ETC). On
the Daimler/Chrysler units, it is referred to as a
Transmission Control Module (TCM). Both of the
controllers are the same and in this manual will be
referred to as a Transmission Control Module (TCM),
regardless of the application.
The TCM receives and monitors various electronic
sensor inputs, and uses this information to shift the
transmission at the optimum time and also controls
line pressure.

The TCM commands shift solenoids and variable
bleed Pulse Width Modulated (PWM) solenoids
within the transmission to control shift timing. The
TCM controls shift feel through the PWM solenoids.
The TCM also controls the apply and release of the
torque converter clutch which allows the engine to
deliver the maximum fuel efficiency without
sacrificing vehicle performance.
On Mercedes vehicles the driver can also choose
between 2 driving programs, "S" for standard driving
programs and "W" for winter driving programs.
Winter option provides a second gear start and a
higher gear ratio for a reverse movement. Standard
mode provides a first gear take off and a lower reverse
gear ratio.
The friction components used in this transmission
consist of six multiple disc clutches. The multiple
disc clutches combine with two mechanical sprag
clutches, to deliver five forward gear ratios, and two
reverse gear ratios, through the gearsets to the output
shaft. Refer to Figure 6 for the internal component
location and application chart for the 722.6
transmission.
