11. Measure the depth of the rivets from the clutch disc lining surface (A) to the rivets (B) on both sides. If
the measurement is less than the service limit,
replace the clutch disc.
12. Remove the ring gear holder. 13. Inspect the ring gear teeth for wear and damage.
14. Inspect the clutch disc mating surface on the
flywheel for wear, cracks, and burning.
15. Measure the flywheel (A) runout using a dial indicator (B). Through at least two full turns with
pushing against the flywheel each time you turn it
to take up the crankshaft thrust washer clearance. If
the measurement is not within the standard,
replace the flywheel, and recheck the runout; go to
step 16.
16. Install the ring gear holder (A).
17. Loosen the flywheel mounting bolts in a cri sscross
pattern in several steps. Remove the bolts, then
remove the flywheel and the ring gear holder.

The electronic control system consists of the powertrain control module (PCM), sensors, and solenoid valves.
Shifting and lock-up are electronically controlled for comfortable driving under all conditions.
The PCM receives input signals from sensors, switches, and other control units, processes data, and outputs signals
for the engine control system and the A/T control system. The A/T control system includes shift control, grade logic
control, clutch pressure control, and lock-up control.
The PCM switches the shift solenoid valves and the A/T clutch pressure control solenoid valves ON and OFF to control
gear selection and torque converter clutch lock-up.

11. Release the clutch end-plate to lower the clutch
end-plate, then put the clutch compressor
attachment on the end-plate (A).
12. Press the clutch compressor attachment down with 150 160 N (15 16 kgf, 33 35 lbf) using a force
gauge, and read the dial indicator (B).
13. The dial indicator reads the clearance (C) between the clutch end-plate and top disc (D). Take
measurements in at least three places, and use
average as the actual clearance.
14. If the clearance is out of the service limit, select a new clutch end-plate from the following table. 1 22551-PRP-003 2.3 mm (0.091 in.)
