Possible reasons:
* Low ATF fluid level: Check the fluid level and condition, add or replace if necessary.
* Contaminated ATF: Over time, the ATF can become contaminated, causing slipping and jerking. Replace fluid and filter.
* Faulty solenoids: Solenoids control gear shifting and faulty solenoids can cause jerking.
* Slipper Clutch: The clutch provides smooth gear changes and wear can cause slipping and jerking.
* Faulty torque converter: The torque converter links the engine and transmission and ensures smooth shifting. Its malfunction can lead to jerking.
* Faulty Speed Sensor: The speed sensor tells the transmission how fast the wheels are spinning, and a faulty one can result in rough shifting and jerking.
*Electronic problems: The electronic control unit (ECU) controls the transmission, and a malfunction can lead to shifting problems.
* Mechanical problems: Worn or damaged internal transmission components such as gears and bearings can cause jerking.
Possible solutions:
* Check and, if necessary, add or replace ATF fluid.
* Replace ATF fluid and filter.
* Send faulty solenoids for repair or replacement.
* Replace the slipper clutch.
* Diagnose the faulty torque converter and repair or replace it if necessary.
* Replace the faulty speed sensor.
* Diagnose transmission control system faults and, if necessary, repair or replace faulty components.
*Consult a qualified mechanic to diagnose and repair mechanical problems.
