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" .

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" .

4. Remove A/T fluid charging pipe and fluid cooler tube.
5. Set manual shaft to position P.
6. Remove park/neutral position (PNP) switch.
7. Remove oil pan and oil pan gasket.
●Do not reuse oil pan bolts.
8. Check foreign materials in oil pan to help determine causes of
malfunction. If the fluid is very dark, smells burned, or contains
foreign particles, the frictional material (clutches, band) may
need replacement. A tacky film that will not wipe clean indicates
varnish build up. Varnish can cause valves, servo, and clutches
to stick and can inhibit pump pressure.
●If frictional material is detected, replace radiator after
repair of A/T. Refer to LC-16, "RADIATOR".
9. Remove control valve assembly according to the following pro-
cedures.
a. Remove control valve assembly mounting bolts A, B and C.
