Control Cable AdjustmentNCAT0111Move selector lever from the ªPº position to the ªLº position. You
should be able to feel the detents in each position. If the detents
cannot be felt or if the pointer indicating the position is improperly
aligned, the control cable needs adjustment.
1. Place selector lever in ªPº position.
2. Loosen control cable lock nut and place manual shaft in ªPº
position.
CAUTION:
Turn wheels more than 1/4 rotations and apply the park lock.
3. Tighten control cable lock nut.
:12-14N×m (1.2 - 1.5 kg-m,9-10ft-lb)
4. Move selector lever from ªPº to ªLº position again. Make sure
that selector lever moves smoothly.
5. Apply grease to contacting areas of selector lever and control
cable. Install any part removed.
Park/Neutral Position (PNP) Switch AdjustmentNCAT01121. Remove control cable end from manual shaft.
2. Set manual shaft in ªNº position.
3. Loosen PNP switch fixing bolts.
4. Usea4mm(0.157 in) pin for this adjustment.
a. Insert the pin straight into the manual shaft adjustment hole.
b. Rotate PNP switch until the pin can also be inserted straight
into hole in PNP switch.
5. Tighten PNP switch fixing bolts.
: 4.9 - 6.8 N×m (0.5 - 0.7 kg-m, 44 - 60 in-lb)
6. Remove pin from adjustment hole after adjusting PNP switch.
7. Reinstall any part removed.
8. Adjust control cable. Refer to ªControl Cable Adjustmentº.
9. Check continuity of PNP switch. Refer to AT-53.
Differential Side Oil Seal ReplacementNCAT01131. Remove drive shaft assemblies. Refer to FA section (ªDrive
Shaftº, ªFRONT AXLEº).
2. Remove oil seals.

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).
