SHEET. Continue Road Test.
3. CHECK SHIFT DOWN (D3 TO 22 )
1. Move selector lever from “D” to “2” position while driving in D
3 (O/D OFF).
2. Does A/T shift from D
3 (O/D OFF) to 22 ?
Read gear position.
Ye s o r N o
Yes >> GO TO 4
No >> Mark the box of “A/T Does Not Shift: D
3→ 22 , When
Selector Lever “D” → “2” Position” on the DIAGNOSTIC
WORKSHEET. Continue Road Test.

3. Tighten belts fixing transaxle.
4. Reinstall any part removed.
5. Adjust control cable. Refer to AT- 4 1 6 , "
Control Cable Adjust-
ment" .
6. Check continuity of PNP switch. Refer to AT- 11 0 , "

PARK/NEUTRAL POSITION (PNP) SWITCH" .
7. Refill transaxle with ATF and check fluid level.
8. 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.
9. Perform road test. Refer to AT-68, "
