Reasons why a Hyundai Sonata Tagaz with automatic transmission may kick:
Problems with the hydraulic system:
*Low transmission fluid level
* Contaminated transmission fluid
* Torque converter malfunction
* Incorrect fluid pressure
* Worn solenoids or valves
Mechanical problems:
* Worn or damaged friction discs
* Worn or damaged gears
* Faulty differential or output shafts
* Faulty speed sensors
Electronic control problems:
*Transmission control module (TCM) malfunction
* Electrical wiring fault
* Software problems
Other possible reasons:
*Low battery voltage
* Worn spark plugs
* Faulty fuel pump
* Air intakes in the intake system
Diagnosis and elimination:
1. Check the level and condition of the transmission fluid: Check the fluid level on a warm transmission and make sure that it is clean and without a burning smell.
2. Scan for error codes: Use an OBD-II scanner to read the error codes stored in the TCM. This may indicate specific problems.
3. Check transmission lines and connections: Inspect lines and connections for leaks or damage.
4. Check transmission fluid pressure: Use a pressure gauge to measure fluid pressure at various stages of transmission operation.
5. Check solenoids: Check the resistance and operation of the solenoids to ensure they are working properly.
6. Replace faulty components: Depending on the diagnostic results, replace any faulty components such as transmission fluid, friction discs or electronics.
Prevention Tips:
* Maintain your transmission regularly, including changing the transmission fluid and filter.
*Use the transmission fluid recommended for your vehicle.
* Avoid sudden acceleration and stopping.
* Repair any transmission fluid leaks as soon as possible.
