Possible causes of automatic transmission kicking when switching:
Mechanical faults:
* Wear of friction discs or steel plates
* Damaged or dirty solenoids
*Low transmission fluid level
* Leaks in the cooling fluid line
* Valve block lock
Electrical faults:
* Faulty engine or transmission speed sensor
* Malfunction of the automatic transmission electronic control unit (ECU)
* Damage to wiring
Insufficient maintenance:
* Timely replacement of transmission fluid and filter
*Using unsuitable fluid
*Transmission overheating
Other reasons:
* Engine or transmission faults (e.g. worn engine mount)
* Severe driving conditions (eg towing a trailer, sudden acceleration)
*Combination of several factors
Diagnostics:
* Visual inspection of the transmission and checking the fluid level
* Scan diagnostic codes to identify faults
* Checking fluid pressure and transmission operating parameters
* Test drive using a data scanner to observe transmission behavior
Solution:
* Replacement of worn parts
* Cleaning or replacing solenoids
* Topping up or replacing fluid
* Leak repair
* Repair or replacement of electrical components
* Timely service
Recommendations:
*Follow the transmission service intervals specified in your owner’s manual.
*Use a high quality transmission fluid recommended by the manufacturer.
* Avoid sudden acceleration and towing heavy loads.
* At the first sign of kicking, seek professional diagnosis and repair.
