Common causes of automatic transmission kicking:
*Low Transmission Fluid: Insufficient lubrication can lead to friction and overheating, leading to kicking.
* Contaminated transmission fluid: Fluid can become contaminated over time, causing sludge and debris to form that impedes fluid flow and blocks valves.
* Defective solenoids: Solenoids shift gears and regulate fluid flow. Worn or faulty solenoids can cause shift lag and shifting noise.
* Worn Friction Discs: Clutch discs, which connect the engine to the transmission, can wear out over time, leading to slippage and kicking.
* Faulty Speed Sensor: The speed sensor tells the transmission how fast the wheels are spinning. A faulty sensor may provide incorrect data, resulting in incorrect shifts.
*Hydraulic block problems: The engine hydraulic block controls the flow of transmission fluid. Malfunctioning or clogged valves can lead to delayed shifts and kicking.
*Software glitches: The Electronic Control Unit (ECU) can experience software glitches, resulting in incorrect signals being sent to the transmission.
*Transmission Cooling System Problems: Insufficient cooling can cause the transmission to overheat, causing the transmission fluid to thin and increase wear.
Less common reasons:
* Worn Engine or Transmission Mounts: Worn mounts can allow the engine or transmission to move, causing vibrations and kicking.
* Driveshaft Problems: An unbalanced or damaged driveshaft can cause vibrations that are transmitted to the transmission.
* Electrical faults: Faulty wiring or components may interrupt signal transmission between the ECU and the transmission.
* Transmission Mechanical Failures: Serious mechanical failures, such as bearing or gear failures, can cause significant kicks and ultimately lead to transmission failure.
