P0734 4GR INCORRECT RATIO

Description

INFOID:0000000008285806

This malfunction is detected when the A/T does not shift into 4GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but by mechanical malfunction such as control
valve sticking, improper solenoid valve operation, etc.

DTC CONFIRMATION PROCEDURE

CAUTION:

• “

TM-95, "Diagnosis Procedure"

” must be performed before starting “DTC CONFIRMATION PROCE-

DURE”.

• Never perform “DTC CONFIRMATION PROCEDURE” before completing the repair, which may cause

secondary malfunction.

• Always drive vehicle at a safe speed.

1.

PRECONDITIONING

If “DTC CONFIRMATION PROCEDURE” is previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before performing the next test.

>> GO TO 2.

2.

CHECK ATF TEMPERATURE

 With CONSULT

1.

Start the engine.

2.

Select “ATF TEMP 1” in “Data Monitor” in “TRANSMISSION”.

3.

Check ATF temperature is in the following range.

 With GST

1.

Start the engine.

2.

Drive vehicle for approximately 5 minutes in urban areas.

Is ATF temperature within specified range?

YES

>> GO TO 3.

NO

>> Drive vehicle to warm ATF or stop engine to cool ATF.

3.

CHECK SYMPTOM (PART 1)

 With CONSULT

1.

Select “4TH GR FNCTN P0734” in “DTC Work Support” in “TRANSMISSION”.

2.

Drive vehicle with manual mode and maintain the following conditions.
