Possible causes of automatic transmission jerking when switching to Mitsubishi:
Mechanical problems:
* Worn or clogged friction discs and bands
* Slip torque converter
* Faulty solenoids
* Clogged oil filter
*Low transmission fluid level
*ATF leaks
Electrical problems:
*Faulty Transmission Control Module (TCM)
* Damaged electrical wiring
* Faulty input or output shaft sensor
Software problems:
* Outdated or corrupt TCM software
* Faults in TCM calibration
Other possible reasons:
* Worn or damaged engine and transmission mounts
*Low battery voltage
* Problems with traction control or stability control
Troubleshooting:
1. Check the level and condition of the transmission fluid: Add or replace the fluid according to the manufacturer’s instructions.
2. Check wiring and sensors: Make sure all connections are secure and there is no damage.
3. Diagnose the TCM: Use a diagnostic scanner to identify trouble codes and check the functionality of the TCM.
4. Check the friction discs and bands: This requires removing and disassembling the automatic transmission.
5. Check the torque converter: The same as in step 4.
6. Reprogram the TCM: If a software problem is found, update or repair the TCM software.
7. Check the engine and transmission mounts: Make sure they are not worn or damaged.
8. Check the battery voltage: Should not be less than 12.6 V with the engine off.
9. Turn off traction or stability control: This may help eliminate the intermittent jerking.
Attention: Do not attempt to repair an automatic transmission yourself unless you have the appropriate skills and knowledge. See a certified mechanic.
