RemovalNCAT0115CAUTION:
Before separating transaxle from engine, remove the crank-
shaft 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 control valve harness connector, PNP switch har-
ness connector, secondary speed sensor harness connector,
dropping resistor harness connector, primary speed sensor
harness connector and body earth harness connector.
4. Remove crankshaft position sensor (OBD) from transaxle.
5. Drain CVT fluid from transaxle.
6. Disconnect control cable from transaxle.
7. Remove exhaust front tube. Refer to FE section (ªEXHAUST
SYSTEMº).
8. Remove drive shafts. Refer to FA section (ªDrive Shaftº,
ªFRONT AXLEº).
9. Disconnect oil cooler hoses.
10. Remove starter motor from transaxle.
Tighten bolts to specified torque.
:41-52N×m (4.2 - 5.3 kg-m, 30 - 38 ft-lb)
11. Support transaxle with a jack.
12. Remove center member.
ITighten center member fixing bolts to specified torque, Refer
to EM section (ªENGINE REMOVALº).
13. Remove rear plate cover.
14. Remove torque converter bolts.
Rotate crankshaft to gain access to securing bolts.
15. Support engine with a jack.
16. Remove transaxle mount bolt. Refer to EM section (ªENGINE
REMOVALº).
17. Remove oil cooler tube (outlet side).
18. Remove transaxle.
InspectionNCAT0236IWhen connecting torque converter to transaxle, measure dis-
tance ªAº to be certain that they are correctly assembled.

2. Install torque converter to drive plate.
IWith converter installed, rotate crankshaft several turns to
check that transaxle rotates freely without binding.
3. Reinstall any part removed.
4. Adjust control cable. Refer to AT-114.
5. Check continuity of PNP switch. Refer to AT-53.
6. Refill transaxle with CVT fluid and check fluid level.
7. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. A slight shock should be felt through the hand gripping
the selector each time the transaxle is shifted.
8. Perform road test. Refer to AT-36.
