DISMOUNTING
1) Take down transmission with engine. For its procedure, refer
to Section 6A1.
2) For 4WD vehicle, remove transfer referring to Section 7D
For 2WD vehicle, remove engine rear mounting No.1
bracket and engine rear mounting No.2 bracket with stiff-
ener.
3) Remove torque converter housing lower plate (1).
4) Remove drive plate bolts.
To lock drive plate (1), engage a flat head rod or the like (2)
with drive plate gear.
5) Remove starting motor.
6) Remove bolts and nut fastening engine and transmission,
then detach transmission from engine.
NOTE:
When detaching transmission from engine, move it in
parallel with crankshaft and use care so as not to apply
excessive force to drive plate and torque converter.
WARNING:
Be sure to keep transmission with torque converter hori-
zontal or facing up throughout the work. Should it be
tilted with torque converter down, converter may fall off
and cause personal injury.

3) Tighten drive plate-torque converter bolts.
Align drive plate bolt hole and torque converter through
starter motor mounting opening then tighten bolts through
torque converter housing lower plate opening.
Lock drive plate (1) by engaging a flat head rod or the like (2)
with drive plate gear.
Tightening torque
Drive plate to torque converter bolts
(a) : 20 N·m (2.0 kg-m, 14.5 lb-ft)
4) Install torque converter housing lower plate (1).
5) Install starter motor.
Tightening Torque
Starter motor bolts : 23 N·m (2.3 kg-m, 16.5 lb-ft)
6) For 4WD vehicle, install transfer referring to Section 7D.
For 2WD vehicle, install engine rear mounting brackets and
stiffener.
7) Remount engine with transmission assembly to vehicle.
Refer to Section 6A1 for its procedure. WARNING:
Be sure to keep transmission with torque converter hori-
zontal or facing up throughout the work. Should it be
tilted with torque converter down, converter may fall off
and cause personal injury.

12) Disconnect couplers from solenoid valves, and transmission
temperature sensor.
Remove transmission temperature sensor.
13) Remove valve body assembly (1).
14) Remove solenoid harness assembly.
15) Remove accumulator pistons and springs.
To remove C0 (1), C2 (2) and B1 (3) accumulator pistons
and springs, position a rag on pistons to catch each piston.
To remove pistons, force low-pressure compressed air (1 kg/
cm
2, 15 psi, 100 kPa, max) into hole (4) as shown in figure,
and pop each piston into the rag.
To remove B0 and C1 accumulator pistons and springs,
remove each snap ring and accumulator spacer, then
remove spring and piston.
16) Remove torque converter housing (1).
a) Remove housing bolts.
b) Remove housing while tapping around it lightly with a plas-
tic hammer. CAUTION:
Be careful not to let manual valve fall off when removing
valve body assembly.
NOTE:
There are three kinds of bolts (bolts A, B and C) fixing
valve body assembly.
2. Bolt A
3. Bolt B
4. Bolt C
NOTE:
Do not push accumulator pistons with fingers or any-
thing before removing them. Pushing them may cause
compressed fluid in accumulator to spew out of hole and
get to your face and clothes.
NOTE:
Never reuse bolts A shown in figure.
