5. Reinstall any part removed.
6. Adjust control cable. Refer to AT-344.
7. Check continuity of PNP switch. Refer to AT-326.
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 ªNº to ªDº, to ª2º, to ª1º and
ªRº positions. A slight shock should be felt through the hand
gripping the selector each time the transaxle is shifted.
10. Perform road test. Refer to AT-83.
