Solution

1. Preparation

Gather necessary tools and parts.
Park the vehicle on a level surface and engage the parking brake.
Disconnect the negative terminal of the battery for safety.

2. Check and Replace Transmission Fluid

Tools Required: Torque wrench, fluid pump, catch pan.
Remove the transmission drain plug using a socket set and allow old fluid to drain completely into the catch pan.
Clean the drain plug and replace the washer if necessary.
Reinstall the drain plug and torque to the manufacturer's specifications (consult the service manual for exact torque values).
Use a fluid pump to fill the transmission with the recommended fluid type (consult the owner’s manual for specifications) until it reaches the proper level.

3. Inspect and Repair Wiring/Connections

Tools Required: Multimeter, wire strippers, electrical tape.
Inspect the wiring harness for any visible damage or wear.
Use a multimeter to check connections for continuity and proper voltage.
Repair or replace any damaged wiring or connectors.

4. Check Transmission Control Module (TCM)

Tools Required: OBD-II scanner.
Reconnect the battery and use the OBD-II scanner to check for any TCM-related codes.
If codes are present, follow the manufacturer’s repair instructions for resetting or reprogramming the TCM.

5. Test Drive

Conduct a test drive to evaluate if the jerking issue has been resolved.
Monitor for any reoccurrence of symptoms.
