REMOVAL AND INSTALLATION
3. Install torque converter to drive plate.
lWith converter installed, rotate crankshaft several turns
to check that transaxle rotates freely without binding.
4. Tighten belts fixing transaxle.
5. Reinstall any part removed.
6. Adjust control cable. Refer toAT-456, "
Control Cable Adjust-
ment".
7. Check continuity of PNP switch. Refer toAT-130, "
DTC P0705
PARK/NEUTRAL POSITION (PNP) SWITCH".
8. Refill transaxle with ATF and check fluid level.
9. Move selector lever through all positions to be sure that tran-
saxle operates correctly. With parking brake applied, idle
engine. Move selector lever through “N” to “D”, to “2”, to “1” and
“R” positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer toAT-69, "
Road Test".
