Electrical System
e. Transmission Upper Valve Body Solenoid
Removal
Note: Before removing the valve body protective cover,
clean the area around the housing to prevent
contamination.
1. Disconnect the negative (-) battery cable at the
negative battery terminal.
2. Remove the six capscrews (Fig. 9-76, 1) four hex-
head capscrews (2), ten washers (3 and 4) and
protective cover (5) secured over the transmission
solenoid cartridge valve (6). Inspect the protective
cover gasket (7); replace if torn or missing.

Body Shown) Removal and Installation
3. Disconnect the internal wire connector (Fig. 9 -76, 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 (Fig. 9 -76, 9),
retaining plate (10) and flat washer (11) securing the
solenoid valve (6) to the transmission.
5. Remove the solenoid valve (Fig. 9-76, 6) and
replace.
f. 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 (Fig. 9-76, 11) and solenoid
valve (6) along with the retaining plate (10). Connect
the internal wire connector (8) 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 (Fig. 9-76, 9) and
torque to 53 lb/in (6 Nm).
3. Install the protective cover gasket (Fig. 9 -76, 7) on
the valve body. Position the protective cover (5) over
the gasket. Install six washers (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 (Fig. 9-76, 4) and four
capscrews (2). Torque to 84 lb/in (9,5 Nm).
5. Connect the negative (-) battery cable to the
negative battery terminal.
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, JLG P/N 8990455 (ZF P/
N 5871 135 002).
g. 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. Disconnect the negative (-) battery cable at the
negative battery terminal.
2. Thoroughly clean the area around the upper and
lower valve body housing.
3. Remove screws securing the upper valve housing to
the transmission.
