P0735 5GR INCORRECT RATIO
DescriptionINFOID:0000000006226833
This malfunction is detected when the A/T does not shift
into 5GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or s horted) but by mechanical malfunction such as control
valve sticking, improper solenoid valve operation, etc.

DTC CONFIRMATION PROCEDURE
CAUTION:
“ TM-127, "
Diagnosis Procedure"” must be performed before star ting “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 c onducted, 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-III
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-III
1. Select “5TH GR FNCTN P0735” in “DTC & SRT confirmation” in “TRANSMISSION”.
2. Drive vehicle with manual mode and maintain the following conditions.

INFOID:0000000006226901
INSPECTION AFTER REMOVAL
Check foreign materials in oil pan to help determine causes of mal-
function. If the ATF is very dark, smells burned, or contains foreign
particles, the frictional material (clutches, band) may need replace-
ment. A tacky film that will not wipe clean indicates varnish build up.
Varnish can cause valves, servo, and clutches to stick and can
inhibit pump pressure.
 If frictional material is det ected, perform A/T fluid cooler
cleaning. Refer to TM-97, "
Cleaning".
INSPECTION AFTER INSTALLATION
Check A/T fluid leakage. Refer to TM-175, "Inspection".
ADJUSTMENT AFTER INSTALLATION
 Adjust A/T fluid level. Refer to TM-95, "Adjustment".
 Perform decel G sensor calibration when replacing control valve & TCM. Refer to TM-92, "
Special Repair
Requirement".
