Possible reasons for automatic transmission kicking in Hyundai Solaris:
*Low transmission fluid (ATF): Check fluid level and add if necessary.
* Contaminated ATF: ATF becomes contaminated over time, causing poor lubrication and overheating. Replace ATF according to manufacturer’s instructions.
* Faulty Shift Solenoid: The solenoids control the flow of ATF inside the transmission. A faulty solenoid can result in incorrect gear shifting.
* Problems with the speed sensor: This sensor tells the automatic transmission about the speed of the vehicle. A faulty sensor may result in incorrect timing of gear shifts.
* Clutch wear: Clutches inside automatic transmissions wear out over time, leading to slippage and kicking.
* Dirty valve body: The valve body controls the flow of ATF inside the transmission. Contamination may result in incorrect gear shifting.
* Torque converter wear: The torque converter connects the engine to the transmission. Its wear can lead to kicking when changing gears.
What to do:
1. Check the ATF level and replace it if necessary.
2. Use only manufacturer-recommended transmission fluid.
3. Record the time and conditions under which the kicking occurs. This will help the mechanic determine the possible cause.
4. Have the transmission diagnosed and repaired by a qualified mechanic.
5. Consider replacing the ATF at a shorter interval than recommended by the manufacturer, especially if the vehicle is driven under severe conditions.
