7. Measure the bushing of the rear sun gear.

Bushing inner diameter

Standard:

29.900—29.921 mm {1.17717—1.17799

in}

Maximum: 29.941 mm {1.17878 in}

• If not as specified, replace the rear sun gear

plate.

8. Install the reverse clutch.

Caution

• Installing the reverse clutch piston may

damage its seal. Carefully install the reverse clutch piston by pushing evenly around the
circumference.

(1) Apply ATF to the circumference of the reverse clutch piston seal, and install the piston into the 2–4 brake

drum.

(2) Install the piston return spring and reverse

return stopper to the reverse piston.

(3) Install the snap ring and the SSTs to the 2–4

brake drum as shown.

Caution

• Depress the piston return spring only

enough to install the snap ring.
Overpressing will damage the piston
return spring assembly edges.

(4) Compress the piston return spring.
(5) Install the snap ring.
(6) Remove the SSTs.
(7) Install the dish plate.
(8) Install the drive and driven plates in the

following order.
Driven—Drive—Driven—Drive

(9) Install the retaining plate.

9. Measure the reverse clutch clearance.

(1) Install the reverse clutch into the end cover,

and set the dial gauge.

(2) Secure the reverse clutch by lightly pressing

down with a press or similar tool.

(3) Apply compressed air to the part indicated in

the figure and let the reverse clutch piston
stroke three times.

Air pressure

392—441 kPa {4.0—4.5 kgf/cm

2

, 57—63 psi}

(4) Apply compressed air and operate the

reverse clutch piston. Read the value when
the indicator of the dial gauge stops.

(5) Release the compressed air and read the dial

gauge when the reverse clutch piston is not
operating.

(6) Calculate the reverse clutch clearance

according to the following formula:
step (4) value – step (5) value = Reverse clutch clearance.

(7) Measure the clearances at four locations (90

°

apart) by following the steps from (3) to (6).
Verify that the average value is within the
specification below.

Reverse clutch clearance

1.00—1.30 mm {0.039—0.051 in}

• If not within the specification, remove the

snap ring and measure its thickness.

(8) Add the thickness to the average value

calculated in step (7), and select the snap ring
whose range includes the value.

Snap ring sizes

(9) Install the selected snap ring and perform steps (2) to (7) again. Verify that the calculated value satisfies the

clearance specification.

10. Inspect the reverse clutch operation.

(1) Install the 2–4 brake drum to the end cover.

11. Install the 3–4 clutch.

Caution

• Installing the 3-4 clutch piston may

damage its seal. Carefully install the 3–4
clutch piston by pushing evenly around
the circumference.

(1) Apply ATF to the circumference of the 3–4 clutch piston seal, and install the piston in to the 3–4 clutch

drum.

(2) Install the spring and retainer.
(3) Apply ATF to the 3–4 seal plate, and install it

onto the 3–4 clutch drum.

(4) Install the SST as shown.

Caution

• Depress the 3–4 seal plate only enough

to install the snap ring. Overpressing will
damage the 3–4 seal plate assembly
edges.

(5) Compress the spring and retainer component

and 3–4 seal plate.

(6) Install the snap ring.
(7) Remove the SST.
(8) Install the drive and driven plates in the

following order.
Driven—Drive—Driven—Drive—Driven—Drive

(9) Install the retaining plate.
