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
body and will drop out when the valve body is turned over.

11. Remove the keeper plates and pins from the 1-2,2-3,3-4, BAR

and CAR valves. The pins can be removed with a magnet.

12. Remove the 1-2,2-3 and 3-4 shift valves.

Notice

The plug is preloaded by the spring and may unexpectedly fall
out of the valve body.

13. Depress the 4-3 sequence valve plug and remove the keeper

plate.

14. Remove the plug, valve and spring.

15. Depress the solenoid 5 valve. Remove the keeper pin and

remove the valve and spring.

Notice

The valve is preloaded by the spring and may unexpectedly fall
out of the valve body.

16. Depress the line pressure release valve, remove the keeper

pin, disc (if fitted), spring and valve.

17. Drive out the roll pin and remove the spring and ball check 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.
