Possible causes of automatic transmission jolts after a complete stop:
1. Low transmission fluid level:
* Check the fluid level in the automatic transmission and add if necessary.
2. Faulty shift solenoid:
* Solenoids control the flow of fluid in the automatic transmission, and their malfunction can lead to shocks when shifting gears.
3. Clogged or dirty automatic transmission filter:
* A clogged filter prevents the free flow of fluid, which can cause shock.
4. Faulty speed sensor:
* The speed sensor informs the automatic transmission control unit about the speed of the vehicle, and its malfunction can lead to incorrect gear shifting.
5. Faulty torque converter clutch:
* The torque converter clutch transmits torque from the engine to the automatic transmission, and wear or malfunction can cause shock.
6. Wiring or electronics problems:
* Faulty wiring or electronic problems can interfere with the operation of the automatic transmission and lead to jolts.
7. Mechanical faults:
* Worn or damaged gears, bearings or other mechanical components of the automatic transmission can cause jerking.
8. Recent Service:
* Improper automatic transmission maintenance, such as using the wrong fluid or careless installation, can cause jerking.
Corrective Action:
* Check the automatic transmission fluid level: Use the dipstick to check the level and, if necessary, add fluid.
* Replace the automatic transmission filter: If the filter is dirty or clogged, replace it.
* Diagnose your vehicle: Use a trouble code scanner or take your vehicle to a service center to diagnose faulty sensors or solenoids.
* Perform repairs: Repair or replace faulty components, including solenoids, sensors, or torque converter clutch.
*Contact a service center: If you cannot solve the problem yourself, please contact an authorized service center for assistance.
