Possible reasons for the automatic transmission jerking when switching in Kia:
1. Low level or contamination of transmission fluid:
*Transmission fluid provides the lubrication and pressure to operate the transmission.
*Low or contaminated fluid levels can cause slipping and jerking.
2. Worn clutches or belts:
* Clutches and belts in the transmission transfer power from the engine to the wheels.
* Their wear and tear over time can lead to slipping, jerking and other problems.
3. Damaged torque converter:
* The torque converter transmits torque from the engine to the gearbox.
* Damage to this component may cause vibration and jerking.
4. Defective wiring or sensors:
* Electrical sensors and wiring control the operation of the transmission.
*Faults in these systems may interfere with gear shifting.
5. Software problems:
* Automatic boxes are controlled by a computer using software.
* Bugs in the software may result in incorrect shifting and jerking.
6. Worn engine or gearbox mounts:
* Engine and transmission mounts absorb vibration from the engine and transmission.
* Worn mounts can allow the engine and transmission to move, which can result in jerking when changing gears.
7. Transmission fluid filter clogged:
* The transmission fluid filter catches contaminants and debris.
* A clogged filter can cause low pressure and jerking.
Solution:
If you experience automatic transmission jerking when changing gears, it is recommended that you contact a qualified mechanic as soon as possible. They will diagnose the problem and perform the necessary repairs to keep your transmission running smoothly.
