P0733 3GR INCORRECT RATIO
Description
INFOID:0000000009480540
This malfunction is detected when the A/T does not shift into 3GR position as instructed by TCM. This is not
only caused by electrical malfunction (circuits open or shorted) but mechanical malfunction such as control
valve sticking, improper solenoid valve operation.
On Board Diagnosis Logic
INFOID:0000000009480541
• This is an OBD-II self-diagnostic item.
• Diagnostic trouble code “P0733” with CONSULT or 20th judgment flicker without CONSULT is detected
when TCM detects any inconsistency in the actual gear ratio.
Possible Cause
INFOID:0000000009480542
• Input clutch solenoid valve
• Front brake solenoid valve
• Direct clutch solenoid valve
• High and low reverse clutch solenoid valve
• Each clutch
• Hydraulic control circuit

.
If “STOP VEHICLE” is detected, go to the following step.
6. Stop vehicle.
7. Drive vehicle in “D” position allowing it to shift from 1GR to 5GR and check shift timing and shift shock.
-
Touch “OK” to complete the inspection when normally shifted from the 1GR to 5GR.
-
Touch “NG” when an unusual shift shock, etc. occurs in spite of shifting from the 1GR to 5GR. Go to
279, "Check Before Engine Is Started"
