c. Transmission Solenoid Valve Removal
1. Unlock and open the engine cover (1).
2. If the vehicle has dual batteries, disconnect both
negative battery cables (3 and 4) from both
batteries.
To access the lower battery (5), loosen the knob (6)
far enough so that the lip (7) on the upper battery box
clears the knob. Lift up the upper battery box (8) and
swing it out, so that the box clears the hydraulic tank
support bracket, to gain access to the lower negative
battery cable (3). Disconnect the lower negative
battery cable.
3. Label and disconnect the wire harness connector
plug (9) on the solenoid valve (10) to be replaced.
4. Remove the socket head capscrew (11), securing
the retaining bracket (12) and solenoid valve (10) to
the transmission. Note the orientation of the solenoid
connector plug (13) for later re-assembly.
5. Remove the solenoid valve (10) and replace.
d. Transmission Solenoid Valve Installation
1. Install the solenoid valve (10) along with the
retaining bracket (12).
2. Install the socket head capscrew (11) and torque to
7.4 - 13.3 lb-ft (10 - 18 Nm).
3. Connect the wire harness connector plug (9) to the
solenoid connector plug (13).
4. If the vehicle has dual batteries, connect both
negative battery cables (3 and 4) to both batteries.
Connect the lower negative battery cable (3) to the
negative (-) terminal on the lower battery (5). Swing
the upper battery box (8) in and make sure that the
lip (7) on the upper battery box slides below the
knob (6). Secure in place with the knob.
5. Lower and lock engine cover. To release and lower
the engine cover (1) from the fully raised position, lift
up slightly on the cover and push the upper part of
the right gas shock (2) (orange tab) to the left. Line
up the upper part of the shock lock tube with the
lower part of the gas shock and pull the cover down
to the closed position.
6. Test the operation of the transmission. Put the
transmission through its entire range of gears
(speeds) in both FORWARD (F) and REVERSE (R)
and check that the transmission also shifts into
NEUTRAL (N).
7. Verify that each function works properly, that the
transmission does not engage when in NEUTRAL
(N) and that the proper indicators illuminate on the
front dash panel.
For further transmission information, refer to Section 6,
“Transmission: ZF 4WG-92/98 TSC & Transfer Case: ZF
TB92-I4.”
