| POSSIBLE CAUSE |
- Clutch slippage (low clutch, low one-way clutch, low and reverse brake)
- In the event of clutch slippage, a DTC (incorrect gear ratio) is output.
- Insufficient engine output (low idle speed, inaccurate ignition timing, reduced compression).
- Insufficient or improper ATF
- Not within line pressure specification
- Shift solenoid A or related circuit malfunction
- Shift solenoid B or related circuit malfunction
- Shift solenoid C or related circuit malfunction
- Shift solenoid F or related circuit malfunction
- Control valve spool malfunction
- Shift solenoid A solenoid hydraulic circuit malfunction
- Shift solenoid B solenoid hydraulic circuit malfunction
- Shift solenoid C solenoid hydraulic circuit malfunction
- Shift solenoid F solenoid hydraulic circuit malfunction
- Improper ground of GND return circuit in AT
- If there is improper ground of GND return circuit, clutch pressure may decrease, causing clutch slippage.
- Torque converter malfunction (improper operation)
