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.
