Possible causes of kicks when switching the Solaris automatic transmission:
1. Malfunction of automatic transmission solenoids:
* Solenoids are responsible for controlling gear shifting. Their failure can lead to hard shifts or slipping.
2. Problems with automatic transmission software:
* Software faults may cause incorrect gear shifting and kicking.
3. Wear of automatic transmission clutches:
* Friction clutches are responsible for transmitting torque. Their wear can lead to slipping and kicking when changing gears.
4. Low transmission fluid level:
* Insufficient fluid levels can result in low oil pressure and difficulty shifting gears.
5. Transmission fluid contamination:
* Dirty fluid can clog the valve body and cause it to malfunction.
6. Torque converter malfunction:
* The torque converter is used to transmit torque from the engine to the gearbox. Its failure can lead to kicking and slipping.
7. Wear of automatic transmission shaft bushings:
* Wear of the bushings can lead to backlash and incorrect operation of gearbox elements.
8. Malfunction of automatic transmission sensors:
* Faulty sensors can transmit incorrect data about transmission performance, which can lead to kicking.
9. Incorrect automatic transmission maintenance:
* Failure to promptly replace transmission fluid or use low-quality fluid can lead to problems with the automatic transmission.
If you notice kicking when shifting gears on your Solaris, it is recommended that you immediately contact a qualified auto mechanic for diagnosis and repair.
