Diagnostic ProcedureECS007SA
1.CHECK VALVE RESISTANCE
1. Turn ignition switch to “OFF” position.
2. Disconnect terminal cord assembly connector in engine compartment.
3. Check resistance between terminal 5 and ground.
OK or NG
OK >> GO TO 2
NG >> 1. Remove oil pan. Refer to AT- 4 0 6 , "
Control Valve
Assembly and Accumulators" .
2. Check the following items:
Torque converter clutch solenoid valve
Refer to AT- 3 7 5 , "
Component Inspection" .
Harness of terminal cord assembly for short or open
2.CHECK POWER SOURCE CIRCUIT
1. Turn ignition switch to “OFF” position.
2. Disconnect TCM harness connector.
3. Check continuity between terminal 5 and TCM harness connector terminal 3.
If OK, check harness for short to ground and short to power.
4. Reinstall any part removed.
OK or NG
OK >> GO TO 3
NG >> Repair open circuit or short to ground or short to power
in harness or connectors.
3.CHECK DTC
Perform AT- 3 7 3 , "

RemovalECS007T4
CAUTION:
Before separating transaxle from engine, remove the crankshaft
position sensor (OBD) from transaxle. Be careful not to damage
sensor.
1. Remove battery and bracket.
2. Remove air duct between throttle body and air cleaner.
3. Disconnect A/T solenoid harness connector, PNP switch har-
ness connector and revolution sensor harness connector.
4. Remove crankshaft position sensor (OBD) from transaxle.
5. Drain ATF from transaxle.
6. Disconnect control cable from transaxle.
7. Disconnect fluid cooler hoses.
8. Remove drive shafts. Refer to AX-10, "FRONT DRIVE SHAFT".
9. Remove the intake manifold support bracket. Refer to EM-16,
"INTAKE MANIFOLD" .
10. Remove starter motor from transaxle.
11. Remove upper bolts fixing transaxle to engine.
12. Support transaxle with a jack.
13. Remove center member.
●Tighten center member fixing bolts to specified torque, Refer
to EM-67, "
ENGINE ASSEMBLY" .
14. Remove center member, engine insulator and engine mounting bracket.
●Tighten center member fixing bolts to specified torque, Refer to EM-67, "ENGINE ASSEMBLY" .

15. Remove suspension member. Refer to SU-5, "FRONTSUSPEN-
SION MEMBER".
16. Remove dust cover from converter housing.
Rotate crankshaft to gain access to securing bolts.
17. Remove securing bolts between drive plate and torque con-
verter. when crank shaft rotates, turn to right at the front side of
engine.
18. Support engine with a jack.
19. Remove bolts fixing transaxle to engine.
20. Lower transaxle while supporting it with a jack.
InstallationECS007T5
1. Check drive plate runout.
CAUTION:
Do not allow any magnetic materials to contact the ring
gear teeth.
●If this runout is out of allowance, replace drive plate with ring
gear.
2. When connecting torque converter to transaxle, measure dis-
tance “A” to be certain that they are correctly assembled.
3. Install torque converter to drive plate.
●With converter installed, rotate crankshaft several turns
to check that transaxle rotates freely without binding.

REMOVAL AND INSTALLATION
4. Tighten bolts fixing transaxle.
5. Reinstall any part removed.
6. Adjust control cable. Refer to AT- 4 0 8 , "
Control Cable Adjust-
ment" .
7. Check continuity of PNP switch. Refer to AT- 111 , "
DTC P0705
PARK/NEUTRAL POSITION (PNP) SWITCH" .
8. Refill transaxle with ATF and check fluid level.
9. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through “N” to “D”, to “2”, to “1” and
“R” positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer to AT- 2 6 6 , "
Road Test" .
