3. Read Trouble Codes: Use an OBD2 scanner to read any stored trouble codes that may indicate an automatic transmission problem.
4. Check sensors: Check the serviceability of the speed sensor and gear selector position sensor.
5. Check solenoids: The solenoids can be checked using an oscilloscope or special diagnostic equipment.
6. Check the valve body: Make sure the valve body is clean and not damaged. If necessary, it can be cleaned or replaced.
7. Update TCU Software: If necessary, update the TCU software to the latest version.
If you do not have experience with automatic transmissions, it is recommended that you contact a qualified mechanic for diagnosis and repair.
