If low, add the correct type of transmission fluid (consult owner’s manual for specifications).
If fluid is burnt or contaminated, proceed to fluid replacement.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, wrench, transmission fluid pump.
Drain the old transmission fluid by removing the drain plug.
Replace the transmission filter:
- Remove the transmission pan bolts using a socket set.
- Carefully lower the transmission pan, allowing excess fluid to drain.
- Replace the old filter with a new one.
- Clean the pan and replace the gasket before reattaching it.

4. Inspect and Repair Wiring

Tools Required: Multimeter, wire strippers.
Inspect the wiring harness connected to the transmission for any frays or corrosion.
Use a multimeter to check for continuity in the wires; repair or replace any damaged wires.

5. Reconnect Battery and Test Drive

Reconnect the battery terminals.
Start the vehicle and let it reach operating temperature.
Perform a test drive to ensure that the jerking issue is resolved.
