11. A/T Does Not Shift: D3 --> D4

SYMPTOM: 

• A/T does not shift from D3 to D4 at the specified speed. 
• A/T must be warm before D3 to D4 shift will occur. 

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 self-diagnosis, after cruise test, show damage to any of the following circuits?

   • Park/neutral position (PNP) switch
   • Overdrive control switch
   • A/T fluid temperature sensor
   • Vehicle speed sensor.A/T (revolution sensor)
   • Shift solenoid valve A or B

   • Vehicle speed sensor.MTR

   Yes or No

   1. Yes: Check damaged circuit. Refer to "DTC P0705 PARK/NEUTRAL POSITION SWITCH " "DTC P0710 A/T FLUID TEMPERATURE SENSOR CIRCUIT " "DTC P0720 VEHICLE SPEED SENSOR.A/T (REVOLUTION SENSOR) " "DTC P0750 SHIFT SOLENOID VALVE A " "DTC P0755 SHIFT SOLENOID VALVE B " or "DTC VEHICLE SPEED SENSOR MTR ".
   2. No: GO TO 3.

3. 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 4.
   2. NG: Repair or replace throttle position sensor [accelerator pedal position (APP) sensor].

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

   OK or NG

   1. OK: GO TO  6.
   2. NG: GO TO 5.

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

   OK or NG

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

   OK or NG

   1. OK: GO TO 7.
   2. NG: Repair or replace damaged parts.
7. CHECK SYMPTOM 

   Check again.

   OK or NG

   1. OK: INSPECTION END 
   2. NG: GO TO 8.
8. 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.
