Precautions for TCM and CVT Assembly Replacement

INSTALLATION

Note the following, and install in the reverse order of removal.

Scheme 122

1. The knurled surface of rib should be upward when installing the control cable to the control device assembly. And insert the control cable securely.
2. After installation is completed, adjust and check CVT position. Refer to «ADJUSTMENT OF CVT POSITION»(ref-234000-S41905427352006052800000) and «CHECKING OF CVT POSITION»(ref-234000-S07514561402006052800000) .

Scheme 123

1. Place selector lever in "P" position.
2. Loosen control cable nut and place manual lever in "P" position. CAUTION: Turn wheels more than 1/4 rotations and apply the park lock.
3. After pushing the control cable with the specified force toward the rear, move your hands off the control cable. Specified force: 9.8 N (1.0 kg, 2.2 lb)
4. Connect control cable on manual lever. CAUTION: No application of a force to the manual lever.
5. Tighten control cable nut. 13N.m (1.3 kg-m, 10 ft-lb)

Scheme 124

Scheme 125

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 transaxle body.
5. The method of operating the lever to individual positions correctly should be as shown in the figure.
6. Confirm the back-up lamps illuminate only when lever is placed in the "R" position. Confirm the back-up lamps do not illuminate when the selector lever is pushed toward the "R" position side with the gear position remained 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 transaxle is locked completely in "P" position.
9. When selector lever is set to manual shift gate, make sure manual mode is displayed on combination meter. Shift selector lever to "+" and "-" sides, and make sure set shift position changes.
