2. Remove the six capscrews (1) four hex-head
capscrews (2), ten lockwashers (3 and 4) and
protective cover plate (5) secured over the
transmission solenoid cartridge valve (6). Inspect the
protective cover gasket (7); replace if torn or
missing.
3. Disconnect the internal wire connector (8) from the
solenoid valve that is being removed. Label the
internal wire connections if removing more than one
solenoid valve.
4. Remove the solenoid capscrew (9), retaining
plate (10) and flat washer (11) securing the solenoid
valve (6) to the transmission.
5. Remove the solenoid valve (6) and replace.
d. Transmission Upper Valve Body Solenoid
Installation
Note: When installing the solenoid valve into the valve
body, position the solenoid valve wires so that they do
not interfere with the protective cover plate.
1. Install the flat washer (11) and solenoid valve (6)
along with the retaining plate (10). Connect the
internal wire connector to solenoid. Insure that the
claw side (12) of the retaining plate is facing down
toward the valve body surface (13).
2. Install the solenoid capscrew (9) and torque to
53 lb-in (6 Nm).
3. Install the protective cover gasket (7) on the valve
body. Position the protective cover plate (5) over the
gasket. Install six lockwashers (3) and
capscrews (1), and tighten until the valve body
spring (14) (upper valve body only) is compressed
and the cover plate sits flush over the gasket.
4. Install the four lockwashers (4) and four
capscrews (2). Torque to 84 lb-in (9,5 Nm).
5. If the vehicle has one battery, connect the
negative (-) battery cable to the negative (-) battery
terminal (15).
If the vehicle has dual batteries, connect both
negative battery cables to both negative (-) battery
terminals (16).
6. Test the operation of the transmission. Put the
transmission through its entire range of gears
(speeds) in both (F) FORWARD and (R) REVERSE,
and check that the transmission also shifts into
(N) NEUTRAL.
7. Verify that each function works properly and that the
transmission does not engage when in (N) NEUTRAL.
For further information, refer to the Transmission Service
Manual, Model ZF 4 WG-98 TC P/N 8990455 (ZF P/N
5871 135 002).
e. Transmission Lower Valve Body Solenoid Removal
Note: In order to service the lower valve body housing,
the upper valve body housing MUST be removed to allow
access to the lower housing protective cover. The area
around the upper and lower valve body housing must be
thoroughly cleaned to avoid contamination of internal
transmission components.
1. If the vehicle has one battery, disconnect the
negative (-) battery cable at the negative (-) battery
terminal (15).
If the vehicle has dual batteries, disconnect both
negative battery cables from both negative (-) battery
terminals (16).
