Possible reasons for the automatic transmission jerking in the Mitsubishi Pajero:
* Malfunctions in the torque converter: wear of friction linings, fluid leakage, contamination.
* Problems with solenoids: malfunction, contamination.
* Malfunction of the electronic control unit (ECU): damage, software.
* Wear or contamination of transmission fluid: decreased level, aging, contamination.
* Problems in the mechanical part of the gearbox: wear of gears, bearings, synchronizers.
* Sensor malfunctions: speed sensor, gear selector position sensor.
* Worn or dirty transmission filter: blocking fluid flow.
* Problems with the driveshaft: imbalance, play.
* Damage to the planetary mechanism: wear of satellites, breakage of gears.
Diagnosis and elimination:
1. According to diagnostics:
* Scan fault codes.
* Checking the level and condition of the transmission fluid.
* Visual inspection of the torque converter and solenoids.
2. For repairs:
* Replacement of faulty solenoids and friction linings in the torque converter.
* Reprogramming or replacing the ECU.
* Replacement of transmission fluid and filter.
* Repair or replacement of mechanical transmission components.
* Replacement of faulty sensors.
* Balancing or replacing the driveshaft.
Note: For correct diagnosis and repair, it is recommended to contact a specialized workshop or an authorized Mitsubishi service center.
