Possible causes of automatic transmission jerking:
Mechanical problems:
* Wear of friction linings
* Torque converter problems
* Faulty speed sensors
* Problems with solenoids
Electrical problems:
* Malfunction of the electronic control unit (ECU) of the automatic transmission
* Open or short circuit in wiring
Hydraulic problems:
*Low or dirty transmission fluid
* Clogged hydraulic filters
* Faulty oil pump
Other reasons:
* Wear of engine or transmission rubber bushings
* Malfunction of the throttle position sensor
What to do:
1. Checking the level and condition of the transmission fluid
* Make sure the fluid level matches the mark on the dipstick.
* Check the color and smell of the liquid. Dark or scorched fluid may indicate transmission problems.
2. Diagnostics
*Consult a mechanic to diagnose the automatic transmission.
* They will be able to use a trouble code scanner to identify any stored codes.
*They can also perform a transmission pressure test and check the condition of the friction linings.
3. Repair
*Depending on the cause of the jerking, transmission parts may need to be replaced or repaired.
*In some cases, replacing fluid or filters may be sufficient.
4. Maintenance
*Change transmission fluid and filters regularly according to manufacturer’s recommendations.
* Avoid sudden starts and stops.
* Tow only the weight limit for your vehicle.
Warning:
*Do not ignore automatic transmission jerking as this may cause further damage to the transmission.
*If you notice any jerking, take it to a mechanic as soon as possible.
