Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cooled down.
Disconnect the battery to prevent electrical shorts.

2. Transmission Fluid Change

Sub-steps:
1. Raise the vehicle using a jack and secure it with jack stands.
2. Locate the transmission fluid pan and remove the drain plug to let the fluid drain completely.
3. Replace the drain plug and tighten it to the manufacturer’s torque specifications.
4. Remove the transmission fluid dipstick to add new fluid.
5. Use a funnel to add the recommended type of transmission fluid (check the owner’s manual for specifications).

3. Inspect and Clean the Transmission Filter

Sub-steps:
1. Remove the transmission pan to access the filter (may require a gasket replacement).
2. Remove the old filter and install a new one, ensuring it is seated correctly.
3. Clean the pan and magnet inside the pan to remove any debris or metal shavings.

4. Electrical Connections Check

Sub-steps:
1. Inspect the wiring harness connected to the TCM for any signs of damage or corrosion.
2. Clean any corroded connectors and ensure tight connections.
3. If necessary, replace damaged wiring or connectors.

5. Reconnect Battery and Test

Sub-steps:
1. Reconnect the battery terminals securely.
2. Start the engine and allow it to reach operating temperature.
3. Conduct a test drive to evaluate if the jerking issue has been resolved.
