Display
Function

Turn signal indicator

ticking
Switching on the turn signal indicator is

indicated acoustically by the turn signal

indicator ticking. The driver's attention is

brought to a defect in the turn signal system

by the turn signal indicator ticking at a higher

frequency.

Turn signal indicator ticking is generated

electromagnetically. The frequency

corresponds to that of the turn signal indicator

lamp.

The signal comes from the combination relay

(turn signal indicator with trailer coupling, rear

window defroster), wiper motor, ATA (N10/2),

on model 210 from the multi-function control
module (N10-1) or from the driver-side signal-

acquisition and actuation module (SAM)

(N10/1), on model 163 from the All-Activity

Module (AAM, N10), on model 168 it is

generated by the integrated turn signal

indicator control in the instrument cluster (A1).

Parking brake reminderThe parking brake warning sounds when

terminal 15g is ON from a speed of approx. 5

km/h.

These conditions are processed in the gear

recognition module (A61) or in the automatic

clutch control module (N15/4). The

Remove/Install
1 - Remove transmission with torque converter. See REMOVE/INSTALL TRANSMISSION WITH
TORQUE CONVERTER.
2 - Put transmission down on workbench. See Fig. 1
.
3 - Take transmission housing (1) off torque converter housing (2). See Fig. 1
.
4 - Pull torque converter housing (2) off transmission housing (1).
5 - Unscrew internal Torx drive bolts (4a) of oil pump (4).
6 - Screw two opposed bolts (a) into the oil pump housing (4) and press the oil pump (4) out of the
converter housing (2) by applying light blows with a plastic hammer.
Inspect
7 - Check oil pump (4).
8 - Check teflon rings (5a) of multi-disk brake B1 (5), replace if necessary.
9 - Install in the reverse order. NOTE: Internal Torx drive bolts (2a) 15 bolts and internal Torx drive bolts (1a) 2
bolts.
NOTE: The intermediate panel (6) on the torque converter housing (2) can usually
be used several times. The panel must not be coated with sealant.
NOTE: Bolt, transmission housing to converter housing. See Fig. 2
.
NOTE: Ensure that the multi-disk clutch K1 (3) does not fall out.
NOTE: Bolt, oil pump with multi-disk brake B1 to converter housing. See Fig. 2
.
NOTE: According to condition: Dismantle and assemble oil pump. See
DISMANTLING & ASSEMBLING OIL PUMP
.
NOTE: Insert both teflon rings (5a) into groove with grease so that the joint stays
together.

Fig. 18: Shift From 1 To 2, Function (Second Gear Engaged)
Courtesy of MERCEDES-BENZ OF NORTH AMERICA.
Aim
Engage front multiple-disc clutch (K1), disengage front multiple-disc brake (B1).
Operation
1st Gear Engaged See Fig. 16.
The end face of the 1-2/4-5 command valve (31a) is kept depressurized via the 1-2 and 4-5 shift solenoid valve
(Y3/6y3). Via the 1-2/4-5 holding pressure shift valve (28a), working pressure (p-A) is applied to the front
mutiple-disc clutch (K1) is depressurized.
Shift Phase
See Fig. 17
Via the 1-2 and 4-5 shift solenoid valve (Y3/6y3), the shift valve pressure (p-SV) is directed onto the end face
of the command valve 1-2/4-5 (31a). The 1-2/4-5 command valve (31a) is displaced and the shift pressure (p-S)
coming from the 1-2/4-5 shift pressure shift valve (29a) via the 1-2/4-5 command valve (31a) is directed to the
front multiple-disc clutch (K1). At the same time the front multiple-disc brake (B1) is subjected to overlap
pressure from the 1-2/4-5 overlap regulating valve (30a).
The B1 pressure acting on the end face of the 1-2/4-5 shift pressure shift valve (29a) is superseded by the
working pressure (p-A). The increasing shift pressure (p-S) at the front multiple-disc clutch (K1) acts on the
annular area of the 1-2/4-5 overlap regulating valve (30a). With an appropriate pressure level at the 1-2/4-5
holding pressure shift valve (28a) this valve switches over.
2nd Gear Engaged
See Fig. 18.
After the gear change is complete, the pressure on the end face of the 12-/4-5 command valve (31a) is reduced
via the 1-2 and 4-5 shift solenoid valve (Y3/6y3) and the command value is pushed back into its original
position. Via the 1-2/4-5 holding pressure shift valve (28a) working pressure (p-A) now reaches the front
multiple-disc clutch (K1) via the 1-2/4-5 command valve (31a).
The front multiple-disc brake (B1) is disengaged (depressurized). The spring in the 1-2/4-5 shift pressure shift
valve (29a) pushes this into its original position.
