Possible reasons:
Lubrication problems:
* Insufficient transmission fluid level
* Fluid degradation or contamination
* Clogged transmission fluid filter
Mechanical problems:
* Worn or damaged clutch or torque converter
* Faulty gear shift solenoids
* Problems with differential or drive shafts
* Worn or damaged bearings or gears
Electrical problems:
* Faulty vehicle speed sensor
*Transmission control module (TCM) malfunction
*Wiring problems
Hydraulic problems:
* Leaks or blockages in the hydraulic system
* Faulty hydraulic pump
*Valve stuck or leaking
Other reasons:
* Worn spark plugs or wires
* Faulty mass air flow (MAF) sensor
* Rotated or damaged drive belt
Steps to resolve the issue:
1. Check the transmission fluid level and condition: If the level is low or the fluid is dirty or burnt, drain and replace it.
2. Replace the transmission fluid filter: This can help clear blockages and improve fluid flow.
3. Scan the vehicle for trouble codes: This may indicate faulty sensors or transmission control problems.
4. Check the clutch or torque converter: These may be mechanical components that are causing the jerking.
5. Repair or replace shift solenoids: These control shifting and can cause jerking when faulty.
6. Diagnostics of the differential and drive shafts: Make sure they are in good condition and do not cause vibrations or jerking.
7. Check bearings and gears: Wear or damage can cause noise, vibration and jerking.
8. Check electrical connections: Make sure all connectors and wires are in good condition and are not causing problems with transmission signals.
9. Repair the hydraulic system: Repair leaks, blockages or faulty pump to ensure proper fluid flow.
10. Replace worn spark plugs or wires: This can improve overall combustion and reduce jerking.
11. Replace the faulty MAF sensor: This can help the ECU regulate the air-fuel mixture correctly and reduce jerking.
12. Check the condition of the drive belt: It should be sufficiently tensioned and should not slip.
