INSTALLATION

Installation is in reverse order of removal. Be careful of the following

1. After installation is completed, adjust and check A/T position.

Scheme 152

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 natural state, tighten control cable nut to specifications. Control cable nut: 14.5 N.m (1.5 kg-m, 11 ft-lb)

Scheme 153

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.

Scheme 155

1. Drain A/T fluid, refer to «CHANGING A/T FLUID»(ref-233319-S28143630952006052500000) .
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 «A/T FLUID COOLER CLEANING PROCEDURE»(ref-233274-S20884774452006052500000) .
