Possible reasons for the automatic transmission kicking when mode D is turned on:
1. Low automatic transmission fluid level
* Check the fluid level and add if necessary.
2. Dirty automatic transmission fluid
* It is recommended to change the automatic transmission fluid every 50,000-75,000 km. Dirty fluid can cause clutch slippage and kicking.
3. Worn or faulty clutches
* Frictions are discs that create clutch and ensure gear shifting. Over time, they can wear out or break, causing kicking.
4. Faulty solenoids
* Solenoids are solenoid valves that control the flow of automatic transmission fluid. Faulty solenoids can cause incorrect shifting and kicking.
5. Problems with the torque converter
* The torque converter is a device that smoothes gear changes and provides torque at low speeds. Torque converter malfunctions can cause kicking.
6. Software errors
* Modern automatic transmissions are controlled by an electronic control unit. Faults in the software can cause shifting problems and kicking.
7. Mechanical malfunctions
* In rare cases, kicking can be caused by mechanical problems such as damaged gears or shafts.
What to do:
* Check the level and condition of the automatic transmission fluid.
*Consult a mechanic for diagnosis and troubleshooting.
* Maintain the automatic transmission regularly (change fluid and filter).
* Avoid aggressive driving and sudden acceleration.
