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

Modulating Pressure Regulating Solenoid Valve, Location

In the supporting body of the electrical control unit (Y3/6) and pressed against the valve housing of the
shift plate (2a) by means of a leaf spring. See Fig. 64
.
Modulating Pressure Regulating Solenoid Valve, Task

To control the modulating pressure depending on the constantly changing operating conditions such as
load/gear changes.
Modulating Pressure Regulating Solenoid Valve, Design

See MODULATING PRESSURE REGULATING SOLENOID VALVE, DESIGN
.
Modulating Pressure Regulating Solenoid Valve, Function

The modulating pressure regulating solenoid valve (Y3/6y1) assigns a proportional pressure to the current
which is controlled by the ETC control module (N15/3) according to the load.

Fig. 83: R/P-Lock, Function (Locking Position)
Courtesy of MERCEDES-BENZ OF NORTH AMERICA.
Function Of R/P Lock - The selector lever position "P" is locked whenever the R/P locking solenoid (89) is not
actuated by the electronic selector lever module control module (N15/5). See Fig. 83
. The prerequisites for this
are as follows:
No voltage supply to the electronic selector lever module control module (N15/5).
Brake pedal not depressed.
Under these conditions the locking lever (90) is in the locking position (P-lock).
The web on the locking lever (P-lock) (90b) locks the locking disc (69). It is not possible to shift the selector
lever (80) out of selector lever position "P".

Operation - When the multiple-disc brake (B) is engaged, the working pressure (p-A) is applied to the end face
of the shift valve (29) via the command valve (31). See Fig. 91
. Its shift condition is retained in the shift phase,

whilst the shift element pressure acting on the end face and which is variable during the shift phase is replaced
by a corresponding, constant pressure.
When the multiple-disc clutch (K) is engaged (K) the end face of the shift pressure shift valve (29) is
depressurized during the stationary and shift phases, here the shift condition is also retained during the shift
phase.
