a. Remove all the bolts except for the two shown.

b. Remove the following from the control valve assembly:

• Clutch pressure solenoid valve

• Clutch pressure switch

• 2-4WD shift solenoid valve

• Line pressure switch

• Transfer fluid temperature sensor

Remove the O-rings from each solenoid valve, switch and termi-

nal body.

d. Place the control valve with the lower body facing up. Remove

the two bolts, and then remove the lower body and separator

plate from the upper body.

CAUTION:

• Do not reuse separator plate.

INSPECTION AFTER DISASSEMBLY

Shift Rod Components

• Check the working face of the shift rod and fork for wear, partial

wear, bending and other abnormality. If any is found, replace with a

new one.

• Measure the clearance between the shift fork and sleeve. If it is out

of specification, replace it with a new one.

• Measure the end play of each pinion gear. If it is out of specifica-

tion, replace the planetary carrier assembly with a new one.

• Check the working face of each gear and bearing for damage,

burrs, partial wear, dents and other abnormality. If any is found,

replace the planetary carrier assembly with a new one.

Sun Gear

• Check if the oil passage of the sun gear assembly is clogged. For

this, try to pass a 3.6 mm (0.142 in) dia. pin through the oil pas-

sage as shown.

• Check the sliding and contact surface of each gear and bearing for

damage, burrs, partial wear, dents, and other abnormality. If any is

found, replace the sun gear assembly with a new one.

Internal Gear

• Check the internal gear teeth for damage, partial wear, dents and

other abnormality. If any is found, replace the internal gear with a

new one.

Gears and Drive Chain

• Check the gear faces and shaft for wear, cracks, damage, and sei-

zure.

• Check the surfaces which contact the sun gear, clutch drum, clutch

hub, press flange, clutch piston and each bearing for damage,

peel, partial wear, dents, bending, or other abnormal damage. If

any is found, replace with a new one.
