A/T Does Not Shift: D3 -> D4

WARNING: This page is about a different car, the 2003 Nissan Pathfinder. However, it is still accessible from the selected car via links, so may be relevant.

SYMPTOM:

A/T does not shift from D ₃ to D ₄ at the specified speed.
A/T must be warm before D ₃ to D ₄ shift will occur.

CHECK SYMPTOM
Are "Vehicle Does Not Creep Forward In "D", "2" Or "1" Position" and "Vehicle Cannot Be Started From D₁ " OK?

Yes or No
1. Yes: GO TO 2.
2. No: Go to "Vehicle Does Not Creep Forward In "D ", "2" Or "1" Position", and "Vehicle Cannot Be Started From D1 ", .
CHECK SELF-DIAGNOSTIC RESULTS
With CONSULT-II

Does self-diagnosis, after cruise test, show damage to any of the following circuits?
- Inhibitor switch
- Overdrive control switch
- A/T fluid temperature sensor
- Revolution sensor
- Shift solenoid valve A or B
- Vehicle speed sensor

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.
CHECK ACCELERATOR PEDAL POSITION SENSOR (THROTTLE POSITION SENSOR)
Check accelerator pedal position sensor (throttle position sensor). Refer to ACCELERATOR PEDAL POSITION SENSOR .
