Mercedes-Benz Sprinter / Dodge Sprinter. Manual — part 460
(14) Remove the transmission oil filter (1) and
o-ring from the electrohydraulic control unit.
(15) Clean the inside of the oil pan (3) of any
debris. Inspect the oil pan gasket (2) and replace if
necessary.
(16) Install a new oil filter (1) and o-ring into the
electrohydraulic control unit.
(17) Install the oil pan (3) and gasket (2) onto the
transmission.
(18) Install the oil pan bolts (5) and retainers (4).
Torque the bolts to 8 N·m (70 in.lbs.).
(19) Lower the vehicle and add 7.0 L (7.4 qts.) of
transmission fluid to the transmission.
(20) Check the oil level (Refer to 21 - TRANSMIS-
SION/AUTOMATIC - NAG1/FLUID AND FILTER -
STANDARD PROCEDURE - CHECK OIL LEVEL).
FREEWHEELING CLUTCH
DESCRIPTION
Freewheeling clutches (Fig. 154) are installed in
the front planetary gear set between the sun gear
and the stator shaft, and in the rear planetary gear
set between the sun gear and the intermediate shaft.
The freewheel consists of an outer race (4), an
inner race (7), a number of locking elements (3) and
a cage (6) for these locking elements.
OPERATION
The freewheeling clutch (Fig. 155) optimizes indi-
vidual gearshifts. They lock individual elements of a
planetary gear set together or against the transmis-
sion housing in one direction of rotation to allow the
torque to be transmitted.
If the inner race (7) of the freewheeling clutch is
locked and the outer race (4) turns counter-clockwise
(1), the locking elements (3) adopt a diagonal position
on account of their special contours, allowing the
freewheel function. The inner race (4) slides under
the locking elements (3) with minimal friction. If the
rotation of the outer race (4) changes to clockwise (2),
the locking elements (3) stand up and lock the outer
and inner races (4, 7) together.

ASSEMBLY
NOTE: The side of the freewheeling clutch F2 (3)
with the markings (directional arrow, part number,
etc.) must be up when the clutch is installed in the
sun gear (4).
(1) Press freewheeling clutch F2 (3) (Fig. 158) into
sun gear (4).
(2) Install snap-ring (2) for freewheeling clutch.
(3) Check O-rings (6) (Fig. 158) on hollow shaft,
replace if necessary.
(4) Install rear sun gear (4) with K3 internally
toothed disc carrier and rear freewheeling clutch (3)
onto the hollow shaft.
(5) Verify proper operation of the freewheeling
clutch F2. When the assembly is held with the F2
clutch snap-ring upward, it should be possible to
rotate the hollow shaft counter-clockwise.
(6) Install retaining ring (5) onto hollow shaft (1).
GEARSHIFT CABLE
DIAGNOSIS AND TESTING
GEARSHIFT CABLE
(1) The floor shifter lever and gate positions
should be in alignment with all transmission PARK,
NEUTRAL, and gear detent positions.
(2) Engine starts must be possible with floor shift
lever in PARK or NEUTRAL gate positions only.
