Changeover Play - Mercedes-Benz GLK-Class Service Manual

The pre-compressed multidisk clutch also acts as a
load change damper. It reduces load change shock
(when changing from acceleration to deceleration
mode and vice-versa).
During a load change, the drivetrain runs through its
entire changeover play. The driver notices this as a
load change shock.
Since the changeover play is much greater on all-
wheel drive vehicles due to the additional drivetrain to
the front axle, load change shock is particularly harsh
on these vehicles.

Tensioning the two drivetrains makes them run
through their changeover play simultaneously. This
allows the load change shock of 4MATIC vehicles to
be reduced to the level of a rear-wheel drive vehicle.
i Changeover play
The changeover play is the total amount of play
between all gears in the drivetrain when the direc-
tion of rotation is changed.
