Revision: October 20052005 QX56
REMOVAL
1. Remove A/T finisher.
Refer to IP-13, "A/T Finisher" .
2. Disconnect selector control cable.
3. Disconnect A/T device harness connector.
4. Remove control device assembly.
INSTALLATION
Installation is in reverse order of removal. Be careful of the following:
After installation is completed, adjust and check A/T position.
Adjustment of A/T PositionECS00CKU
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 PositionECS00CKV
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” posi-
tion 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 PanECS00CKW
REMOVAL AND INSTALLATION
Removal
1. Drain A/T fluid, refer to MA-24, "Changing A/T Fluid" .
2. Remove oil pan and gasket.
3. 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- 1 3 , "
A/T FLUID
COOLER CLEANING PROCEDURE" .
4. Remove magnets from oil pan.
Installation
1. Install the oil pan magnets as shown.

2. Install the oil pan and new oil pan gasket.
CAUTION:
Be sure the oil pan drain plug is located to the rear of the
transmission assembly.
Before installing oil pan bolts, remove any traces of old
sealant from the sealing surfaces and threaded holes.
Do not reuse old gasket, replace with a new one.
Always replace the oil pan bolts as they are self-sealing.
Partially install the oil pan bolts in a criss-cross pattern to
prevent dislocation of the gasket.
3. Tighten oil pan bolts in numerical order as shown.
4. Install drain plug in oil pan.
CAUTION:
Do not reuse old drain plug gasket replace with a new one.
5. Refill the transmission assembly with fluid. Refer to MA-24, "
Changing A/T Fluid" .
