| POSSIBLE CAUSE |
- There is a malfunction in the signal circuit which controls shifting (APP sensor, input/turbine speed sensor, vehicle speed sensor), the control valve is stuck, the accumulator (forward or servo apply) is stuck, or the clutch circuit is stuck.
NOTE:
- If a tire of a different diameter from the standard tire is installed, the TCM determines that the driving mode is the AAS mode, and may change to a different shift timing from the normal timing.
- Clutch slippage, burnt
- Line pressure low
- Control valve body malfunction
- Shift solenoid D malfunction
- Shift solenoid E malfunction
- Shift solenoid F malfunction
- Shift solenoid A malfunction
- Shift solenoid B malfunction
- Shift solenoid C malfunction
- Pressure control solenoid B malfunction
- Body GND malfunction
- Signal malfunction
- VSS malfunction
- Sensor GND malfunction
- APP sensor malfunction
- Input/turbine speed sensor malfunction
- TR switch malfunction
- Selector cable adjustment incorrect
- TR switch adjustment incorrect
- Wheel speed signal malfunction
- Tire of a different diameter from the standard tire is installed
- ABS wheel-speed sensor malfunction
NOTE:
- Before following the troubleshooting steps, make sure that the Automatic Transaxle On-Board Diagnostic and Automatic Transaxle Basic Inspection are conducted.
