Possible causes of automatic transmission kicking:
*Low transmission fluid level: Check the fluid level and add fluid if necessary.
* Poor quality transmission fluid: Old or dirty fluid can affect the operation of valves and clutches, causing slipping and kicking.
* Clogged Oil Filter: A clogged oil filter can restrict fluid flow, resulting in increased pressure and shifting kicks.
* Faulty solenoids: The solenoids control the flow of fluid through the valves. A faulty solenoid can cause valves to malfunction and kick.
* Worn Clutches: Clutches can wear out over time, leading to slipping and kicking.
* Faulty planetary gears: Planetary gears can wear out or fail, causing slippage and kicking.
* Faulty valve body: The valve body is the brain of the automatic transmission and controls the flow of fluid. A faulty valve body can cause valves to malfunction and kick.
*Faulty Transmission Speed Sensor: A faulty sensor can provide incorrect transmission speed information, resulting in incorrect shifting and kicking.
*Faulty Throttle Position Sensor: A faulty throttle position sensor can provide incorrect information about the throttle position, causing the transmission to malfunction and kick.
* Electronics problems: The electronic transmission control unit (ECU) may fail, causing the automatic transmission to malfunction and kick.
What to do:
* Check the level and quality of the transmission fluid.
* Replace the oil filter.
* Scan the vehicle for fault codes.
* Check solenoids, planetary gears and valve body.
* Check the transmission speed and throttle position sensors.
* Inspect the electronics for problems.
Warning: Transmission kicking may indicate a serious problem that could damage the transmission. It is important to contact a qualified car service center for diagnosis and repair as soon as possible.
