1. Place the shift selector handle (1) in “N” position.
2. Slide shift selector handle cover (2) downward.
3. Pull out shift selector handle clip (3) from shift selector handle (1).
4. Remove shift selector handle (1) and shift selector handle cover (2) as a set from shift selector.
CAUTION:
Do not push shift selector handle button.
INSTALLATION
1. Insert shift selector handle clip (1) to shift selector handle (2).
2. Install shift selector handle cover (3) to shift selector handle (2).
3. Place the shift selector in “N” position.
4. Install shift selector handle over shift selector until a click is felt.
CAUTION:
• Do not tilt shift selector hand le when installing. Install it
straight, and do not tap or ap ply any shock to install it.
• Do not push shift selector handle button.
Adjustment of A/T PositionINFOID:0000000005928275
Move shift selector from “P” position to “1” position. You should be able to feel the detents in each position. If
the detents cannot be felt or if the position indicator is improperly aligned, the control cable needs adjustment.
CAUTION:
Make sure that parking brake is applied before adjustment.
1. Remove the air duct assembly. Refer to EM-135
.
2. Remove the control cable nut (A) and control cable (1) and place the manual lever (2) in the "P'"position.
3. Place shift selector in “P” position.
4. Hold control cable (1) at the end and pull it with a force of 9.8 N (approximately 1 kg, 2.2 lb). Release the control cable and tem-
porarily tighten control cable nut (A).
5. Tighten control cable nut (A) to the specified torque.
CAUTION:
Secure manual selector when tightening nut.
6. Move shift selector from “P” to "1" position again. Make sure that shift selector moves smoothly.
7. Check A/T position. Refer to AT-217, "
Checking of A/T Position".
8. Install air duct assembly. Refer to EM-135
.
Checking of A/T PositionINFOID:0000000005928276
1. Place shift selector in “P” position, and tu rn ignition switch ON (Do not start engine).
2. Make sure shift selector can be shifted to other than “P” position when brake pedal is depressed. Also make sure shift selector can be shifted from “P” position only when brake pedal is depressed.
3. Move shift selector and check for excessive effort, sticking, noise or rattle.
4. Confirm shift selector stops at each position with the feel of engagement when it is moved through all the
positions. Check whether or not the ac tual position shift selector is in matches the position shown by the
position indicator and the transaxle.

REMOVAL AND INSTALLATION
Removal
1. Disconnect the battery negative terminal.
2. Remove engine under cover and fender protector (LH). Refer to EI-26, "
Removal and Installation".
3. Drain the A/T fluid. Refer to AT- 1 7
.
4. Remove oil pan and oil pan gasket.
5. Check for foreign materials in oil pan to help determine cause of malfunction. If the ATF is very dark, smell burned or contains for-
eign particles, friction material (clutches, band) may need
replacement. A tacky film that will not wipe clean indicates var-
nish build up. Varnish can cause valves, servo, and clutches to
stick and can inhibit pump pressure.
•If ATF contains frictional ma terial (clutch, bands, etc.),
replace radiator and flush cool er line using cleaning sol-
vent and compressed air after repair of A/T. Refer to CO-
40.

• When replacing an engine or transmission you must make sure any dowels are installed correctly during re-assembly.
• Improper alignment caused by missing dowels may cause vibration, oil leaks or breakage of drive
train components.
• Do not reuse O-rings and copper washers. Refer to "COMPONENTS".
• When turning crankshaft, turn it clockwise as viewed from the front of the engine.
• When tightening the bolts for th e torque converter while securing the crankshaft pulley bolt, be sure
to confirm the tightening torque of the crankshaft pulley bolt. Refer to EM-159
.
• After converter is installed to drive plate, ro tate crankshaft several turns to check that transaxle
rotates freely without binding.
• When installing the torque converter to the transaxle measure dis- tance A.
• Check the fitting of the dowel pins when installing the transaxle assembly and the engine assembly.
