Valve Body
To disassemble the valve body, proceed as follows.
1. Remove the detent spring and retainer plate using a T40 Torx bit.
Notice
Be aware that the manual valve will fall out of the valve body.
2. Take note of the angular relationship of the solenoid terminals
to the valve body, then slide the manual valve out of the lower
valve body.
3. Remove the solenoid and valve assembly as follows:
!
solenoid 1
!
solenoid 2
!
solenoid 3
!
solenoid 4
!
solenoid 5
!
solenoid 6
4. Place the valve body assembly on the bench with the upper
body uppermost.
5. Remove the 24 clamping screws with a No. 30 Ton bit. Separate
the upper and lower valve bodies by lifting the upper body and
the separator plate together.
6. Upper body over and place it on the bench with the separator
plate uppermost.
7. Lift the separator plate and gaskets from the upper valve body.
8. Remove the five nylon check balls exposed in the valve body.
9. Remove the retainer plate, plug, spring and reverse lockout
valve.
10. Remove the two filters (and the large nylon check ball) from the
lower valve body.
Notice
Once the pins are removed, the plates are loose in the valve

ASSEMBLY PROCEDURE
The transmission is assembled in modular fashion and details
of assembly for each module are given under the appropriate
subject. Refer to table 8.1 (at the end of Section 8.3) for the
torque specifications to be applied, and to table 9.10 in section
9.6 for details of all special tools required, when performing
assembly procedures. Technicians overhauling these
transmissions will also require a selection of good quality Torx
bit sockets, in particular numbers 30,40 and 50, and an 8 mm,10
mm and 12 mm double hex socket.
Transmission
Notice
1. Ensure that the B1R circlip is fitted to the case. (If this is not
fitted, the valve will peen its way into and through the
separator plate.)
2. Ensure that the ‘E’ clip is fitted to the cross shaft.
3. Ensure that all aspects of the parking mechanism are
working.
To assemble the transmission, proceed as follows:
1. Turn the transmission case upside down on the bench and
mount it to the transmission cradle No.0555-331895.
2. Install all fittings, plugs and the breather, applying a sealant
where applicable, Tighten the fittings to specifications.
Ensure that the breather is clear, and check that the lube
fitting in the rear of the case is fitted and clear of obstruction.
3. Assemble the B1R valve and spring, and secure with the
irclip. Refer to Ensure that the circlip is completely seated
in its groove.
4. Install the rear servo lever and pivot pin.
Notice
The lever must pivot freely on its pin.
AUTOMATIC TRANSMISSION 5A-95
Notice
Care must be taken when applying sealant to ensure that it is
not applied between the pin and the lever.
5. Assemble the park rod lever, complete with the return spring
and pivot pin, applying a small amount of sealant to the
outer end of the pivot pin.
Notice
That the lever must pivot freely on its pin and the spring
must return the park rod lever to its correct location.
6. Secure the pivot pin with the circlip.
Notice
The pawl must pivot freely on its pin.
7. Install the parking pawl pivot pin and spring.
8. Connect the park rod to the manual valve detent lever.
Ensure the spring and cam collar is firmly installed on the
rod.

9. Check that the cam collar slides freely on the rod.
10. Insert the cross shaft into the case, from the side opposite
to the inhibitor switch, then install the anti-rattle spring on
the shaft.
11. Position the manual valve detent lever, aligning it with the
cross-shaft bore in the case.
12. Push the shaft through the detent lever until it starts in the
detent lever side of the case.
13. Install the detent lever drive pin in the shaft using tool No.
0555-331897 with the adaptor over the pin.
14. Press the pin into the shaft until the tool bottoms.
15. Remove the tool and fit the spring retaining circlip to the
shaft.
16. Install the new cross shaft seals using tool No. 0555-
331894.
17. Install the inhibitor switch on the case. Torque the screws
as per specifications. Press the pin into the shaft until the
tool bottoms (4WD models) using tool No.0555-332942.
18. Thoroughly check the terminal wiring loom for condition
and continuity.
19. Position the loom and locate the solenoid 7 contact and
terminal in the pump mounting flange at the front of the
case. The solenoid 7 wire is routed under the park rod
and cross shaft in the case.
