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, 3, 2 Or 1 Position" and "8. Vehicle Cannot Be Started From D1" OK?

   Yes or No

   1. Yes: GO TO 2.
   2. No: Go to "7. VEHICLE DOES NOT CREEP FORWARD IN D, 3, 2 OR 1 POSITION  and "8. VEHICLE CANNOT BE STARTED FROM D1 ".
2. CHECK SELF-DIAGNOSTIC RESULTS 

   With CONSULT-II 

   Does "TCM INPUT SIGNALS" in "DATA MONITOR" show damage to park/neutral position (PNP) switch circuit?

   Without CONSULT-II 

   Does self-diagnosis show damage to park/neutral position (PNP) switch circuit?

   Yes or No

   1. Yes: Check park/neutral position (PNP) switch circuit. Refer to "DTC P0705 PARK/NEUTRAL POSITION SWITCH ".
   2. No: GO TO 3.

3. CHECK VEHICLE SPEED SENSOR.A/T AND 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) " and "DTC VEHICLE SPEED SENSOR MTR ".

   OK or NG

   1. OK: GO TO 4.
   2. NG: Repair or replace vehicle speed sensor.A/T (revolution sensor) and vehicle speed sensor.MTR circuits.
4. CHECK THROTTLE POSITION SENSOR [ACCELERATOR PEDAL POSITION (APP) SENSOR] 

   Check throttle position sensor [accelerator pedal position (APP) sensor]. Refer to "DTC P0122, P0123: TP SENSOR " and "DTC P2122, P2123: APP SENSOR " (with QR25DE), or "DTC P0122, P0123: TP SENSOR " and "DTC P2122, P2123: APP SENSOR " (with VQ35DE).

   OK or NG

   1. OK: GO TO 5.
   2. NG: Repair or replace throttle position sensor [accelerator pedal position (APP) sensor].

5. CHECK A/T FLUID CONDITION 
   1. Remove oil pan.
   2. Check A/T fluid condition.

   OK or NG

   1. OK: GO TO  7.
   2. NG: GO TO 6.

6. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve. Refer to "CONTROL VALVE ASSEMBLY AND ACCUMULATORS ".
   2. Check the following items:
      • Shift valve A
      • Shift solenoid valve A
      • Pilot valve
      • Pilot filter
   3. Disassemble A/T.
   4. Check the following items:
      • Servo piston assembly
      • Brake band
      • Oil pump assembly

   OK or NG

   1. OK: GO TO  8.
   2. NG: Repair or replace damaged parts.
7. DETECT MALFUNCTIONING ITEM 
   1. Remove control valve. Refer to "CONTROL VALVE ASSEMBLY AND ACCUMULATORS ".
   2. Check the following items:
      • Shift valve A
      • Shift solenoid valve A
      • Pilot valve
      • Pilot filter

   OK or NG

   1. OK: GO TO 8.
   2. NG: Repair or replace damaged parts.
8. CHECK SYMPTOM 

   Check again.

   OK or NG

   1. OK: INSPECTION END 
   2. NG: GO TO 9.
9. CHECK TCM INSPECTION 
   1. Perform TCM input/output signal inspection.
   2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

   OK or NG

   1. OK: INSPECTION END 
   2. NG: Repair or replace damaged parts.
