A/T Does Not Shift: D1->D2 or Does Not Kickdown: D4->D2

9. A/T Does Not Shift: D1 -> D2 Or Does Not Kickdown: D4 -> D2

SYMPTOM:
A/T does not shift from D1 to D2 at the specified speed.
A/T does not shift from D4 to D2 when depressing accelerator pedal fully at the specified speed.

1. CHECK SYMPTOM
Are "7. Vehicle Does Not Creep Forward In D, 2 Or 1 Position" and "8. Vehicle Cannot Be Started From D1 " OK?
Yes or No
Yes >>GO TO 2.
No >> Go to "7. Vehicle Does Not creep Forward In "D", "2" Or "1" Position", "8. Vehicle Cannot Be Started From D1".

2. CHECK PNP SWITCH CIRCUIT
With CONSULT-II





Does "TCM INPUT SIGNALS" in "DATA MONITOR" show damage to PNP switch circuit?
Without CONSULT-II
Does self-diagnosis show damage to PNP switch circuit?
Yes or No
Yes >> Check PNP switch circuit. Refer to "DTC P0705 PARK/NEUTRAL POSITION (PNP) SWITCH".
No >> GO TO 3.

3. CHECK VEHICLE SPEED SENSOR A/T AND CHECK VEHICLE SPEED SENSOR MTR CIRCUIT
Check vehicle speed sensor A/T (revolution sensor) and vehicle speed sensor MTR circuit. Refer to "DTC P0720 VEHICLE SPEED SENSOR A/T (REVOLUTION SENSOR)", "DTC VHCL SPEED SEN MTR VEHICLE SPEED SENSOR MTR".
OK or NG
OK >>GO TO 4.
NG >> Repair or replace vehicle speed sensor A/T (revolution sensor) and vehicle speed sensor MTR circuits.

4. CHECK THROTTLE POSITION SENSOR





Check throttle position sensor.
OK or NG
OK >> GO TO 5.
NG >> Repair or replace throttle position sensor.

5. CHECK A/T FLUID CONDITION





1. Remove oil pan.
2. Check A/T fluid condition.
OK or NG
