P0733 3GR INCORRECT RATIO
Description
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 by mechanical malfunction such as control valve sticking, improper solenoid valve operation, etc.
On Board Diagnosis Logic
- This is an OBD-II self-diagnostic item.
- Diagnostic trouble code "P0733" with CONSULT-III or 20th judgment flicker without CONSULT-III is detected when TCM detects any
inconsistency in the actual gear ratio.
Possible Cause
- Input clutch solenoid valve
- Front brake solenoid valve
- Direct clutch solenoid valve
- High and low reverse clutch solenoid valve
- Each clutch and brake
- Hydraulic control circuit
