1.CHECK SHIFT DOWN (D4 TO D3 )
1. Confirm overdrive control switch is in “ON” position.
2. Confirm selector lever is in “D” position.
3. Accelerate vehicle using half-throttle to D
4 .
4. Release accelerator pedal.
5. Set overdrive control switch to “OFF” position while driving in D
4
.
6. Does A/T shift from D
4 to D3 (O/D OFF)?
Read gear position and vehicle speed.
Ye s o r N o
Ye s > > G O T O 2
No >> Mark the box of “A/T Does Not Shift: D

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
