Cause 1: Low ATF (transmission fluid) level
*Low ATF fluid levels can cause oil starvation and wear on transmission components, causing hesitation.
Cause 2: Contaminated or burnt-out ATF
* Contaminated or burnt-out ATF fluid loses its lubricating and cooling properties, which leads to increased wear and shock.
Reason 3: Malfunction of solenoids
* Solenoids are used to change gears in automatic transmissions. Faulty or clogged solenoids can cause delays or jerks when shifting.
Reason 4: Worn clutches
* Clutches are used to transmit torque between transmission components. Worn or damaged clutches can cause slipping and jerking.
Reason 5: Torque converter malfunction
* The torque converter is part of the automatic transmission, responsible for transmitting torque from the engine to the transmission. A faulty torque converter can cause shock when shifting gears.
Reason 6: Electrical wiring problems
* Electrical problems, such as broken or broken wires, can affect the operation of solenoids and other transmission components, causing vibrations.
Solution:
* Check the level and condition of the ATF fluid. Top up or replace if necessary.
* Flush ATF and replace it at recommended intervals.
* Check and replace faulty solenoids.
* Diagnose and repair worn clutches.
* Replace the faulty torque converter.
* Fix any electrical wiring problems.
