Fig. 3 Installing Holding Fixture:

4. To prevent rotation of the piston, engage the pawl of the special tool (MD 998196-1-01) into the notch of the piston, and using the adapter (MD998918), fix the piston as shown.

Caution:
1. Don't press the piston in with the special tool.
2. When mounting the adapter on the transaxle case, tighten it by hand. Don't apply much torque.

Fig. 9 Loosening Locknut:

5. Loosen the locking nut to before the V groove of the adjusting rod, and tighten the special tool (inner) until it contacts the locking nut.

Kickdown Servo Adjustment:

6. Engage the special tool (MD998916-2-01 outer) on the lock nut. Rotating the outer cylinder counter clockwise and the inner cylinder clockwise, lock the locking nut and special tool (MD 998916-3-01 inner).

Kickdown Servo Torque Adjustment:

7. Attach the torque wrench to the special tool (inner), and repeat "tightening" and "returning" at a torque of 10 Nm (7.2 ft.lbs.) two times. Then, tighten it to a torque of 5 Nm (3.6 ft.lbs.). Then, back off the special tool (inner) 2 to 21/4 turns.

Kickdown Servo Adjustment:

8. Engage the special tool (outer) on the locking nut. Rotating the outer cylinder clockwise and the inner cylinder counterclockwise, unlock the locking nut and special tool (inner).

Caution: When unlocking the lock, apply equal force to both tools.

Kickdown Servo Torque Adjustment:

9. Tighten the locking nut by hand until the locking nut contacts the piston. Then, using the torque wrench, tighten to the specified torque.

Locking nut: 25-32 Nm (18-23 ft.lbs.)

Caution: If it is rapidly tightened with the socket wrench or torque wrench, the lock nut and adjusting rod may rotate together.

10. Remove the special tool which fastens the piston. Attach the plug to the outlet of the low reverse pressure.
