SHIFT CONTROL SYSTEM
Adjustment of A/T Position
INFOID:0000000003532475
1. Loosen nut of control cable.
2. Place PNP switch and selector lever in “P” position.
3. After pushing the control cable in the direction shown with a
force of 9.8 N·m (1kg-m, 2.2 lb-ft), release it. This is in the natu-
ral state, tighten control cable nut to specifications.
Checking of A/T PositionINFOID:0000000003532476
1. Place selector lever in “P” position, and turn ignition switch ON
(engine stop).
2. Make sure selector lever can be shifted to other than “P” position
when brake pedal is depressed. Also make sure selector lever
can be shifted from “P” position only when brake pedal is
depressed.
3. Move the selector lever and check for excessive effort, sticking,
noise or rattle.
4. Confirm the selector lever stops at each position with the feel of
engagement when it is moved through all the positions. Check
whether or not the actual position the selector lever is in
matches the position shown by the shift position indicator and
the transmission body.
5. The method of operating the lever to individual positions correctly should be as shown.
6. Confirm the back-up lamps illuminate only when lever is placed in the “R” position. Confirm the back-up
lamps does not illuminate when selector lever is pushed against “R” position in the “P” or “N” position.
7. Confirm the engine can only be started with the selector lever in the “P” and “N” positions.
8. Make sure transmission is locked completely in “P” position.Control cable nut : 14.5 N·m (1.5 kg-m, 11 ft-lb)

Oil PanINFOID:0000000003532477
REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid. Refer to AT-13, "Changing Automatic Transmission Fluid (ATF)".
2. Remove oil pan clips (1).
3. Remove oil pan (2).
4. Remove oil pan gasket.
• : Front
• : Oil pan bolts
• Drain plug (3)
5. Check foreign materials in oil pan to help determine cause of malfunction. If the A/T fluid is very dark, has
some burned smell, or contains foreign particles, friction 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.
CAUTION:
If friction material is detected, flush the transmission cooler after repair. Refer to AT-15, "
A/T Fluid
Cooler Cleaning".
6. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.

• : Front
• : Oil pan bolts
CAUTION:
• Do not reuse the oil pan gasket.
• Completely remove all moisture, oil and old gasket from

4. Install drain plug in oil pan with new gasket.
CAUTION:
Do not reuse the drain plug gasket.
5. Refill the transmission assembly with fluid. Refer to AT-13, "
