General
This section covers the repairs related
to the clutch, manual and automatic
transmissions, shift linkages,
driveshafts, and transfer case (all
wheel drive vehicles only). For repairs
related to drive axles and front and rear
final drive differentials, see
Front Axle Final Drive
Axle Final Drive.

Drivetrain

E46 models are equipped with a
longitudinal drivetrain. The
transmission is bolted directly to the
rear of the engine. In rear wheel drive
models, a driveshaft connects the
output shaft of the transmission to the
rear final drive. On all wheel drive
models, a transfer case is mounted to
the rear of the transmission, with drive
shafts leading to front and rear final
drive assemblies. Individual drive axles
with integrated constant velocity joints
transfer rotational power from the final
drive units to the drive wheels.

Manual transmission

Due to different power characteristics
and performance requirements, three
different manual transmissions are
used in models covered by this
manual. Manual transmission
applications are given in
