Possible causes of jerking when changing gears in an automatic transmission:
1. Problems with automatic transmission fluid:
*Low fluid level
* Contaminated liquid
* Deterioration of liquid properties
2. Damage or wear of mechanical components:
* Worn friction discs
* Faulty solenoids
* Clogged valve body
*Worn gear
3. Electrical faults:
* Faulty gear selector position sensor
*Speed sensor malfunction
*Wiring fault
4. Software problems:
* Errors in the transmission control unit software
* Incorrectly installed software update
5. Low automatic transmission fluid pressure:
* Faulty oil pump
* Clogged oil filters
* Worn seals
6. Problems with the torque converter:
* Worn drain bearing
* Faulty locking mechanism
What to do if the automatic transmission shifts jerkily:
1. Check the level and condition of the automatic transmission fluid:
* Make sure the fluid level is correct and that it is not dirty or has a burning smell. Replace fluid and filter if necessary.
2. Take the car to a car service:
*If the automatic transmission fluid check does not reveal any problems, have the problem diagnosed by a qualified mechanic.
3. Do not continue driving:
* If the automatic transmission shifts violently, do not continue driving as this may cause further damage to the transmission. Call a tow truck or have your car towed to a service center.
4. Be careful when changing gears:
*When changing gears in manual mode, shift smoothly and avoid sudden movements that can aggravate jerking.
5. Maintain the automatic transmission regularly:
* Observe the recommended intervals for changing the automatic transmission fluid and filter. Regular maintenance can help prevent jerking and extend the life of your transmission.
