Possible causes of transmission jerking in a Ford Mondeo automatic transmission:
1. Low transmission fluid level:
* Insufficient fluid levels cause clutches to slip, resulting in jerking.
2. Contaminated transmission fluid:
* Contamination reduces the fluid’s effectiveness over time, causing shifting problems and jerking.
3. Worn solenoids:
* Solenoids control fluid flow in the transmission. Their wear can interfere with proper gear shifting.
4. Faulty sensors:
* Speed and position sensors monitor the operation of the gearbox. Their malfunction can lead to incorrect gear shifting and jerking.
5. Problems with the torque converter:
* The torque converter connects the engine to the transmission. If it malfunctions, it can cause the clutch to slip and jerk.
6. Faulty Transmission Control Unit (TCU):
* The TCU controls the operation of the transmission. Its malfunction may interfere with gear shifting.
7. Worn clutches:
* Clutches are located in the gearbox and transmit power from the engine to the wheels. Their wear can cause slipping and jerking.
8. Electrical problems:
*Electrical problems, such as a faulty wiring harness or electronic module, can interfere with transmission operation.
9. Software problems:
* Errors in the transmission software may result in incorrect gear shifting.
What to do if the Ford Mondeo gearbox jerks:
* Check the transmission fluid level.
* Inspect the transmission fluid for contamination.
* Scan your vehicle for trouble codes.
*Consult a qualified mechanic for diagnosis and repair.
