Tools Required: Funnel, fluid pump, transmission fluid (as specified in the owner's manual).
Sub-steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick or fill plug and check the fluid level.
3. If fluid is low, fill with the recommended transmission fluid until the proper level is reached.
4. If fluid is discolored or burnt, drain the old fluid using a fluid pump.
5. Replace the old fluid with new fluid according to specifications.

3. Replace Transmission Filter

Tools Required: Socket set, new transmission filter, gasket, transmission fluid.
Sub-steps:
1. Remove the transmission pan using a socket set.
2. Carefully take out the old filter and discard it.
3. Clean the transmission pan and remove old gasket material.
4. Install the new filter, ensuring it is seated properly.
5. Reinstall the transmission pan with a new gasket and torque bolts to manufacturer specifications.

4. Electrical Inspection and Repair

Tools Required: Multimeter, wiring diagram, dielectric grease.
Sub-steps:
1. Inspect the wiring harness for any signs of damage, corrosion, or loose connections.
2. Use a multimeter to test the voltage at the transmission control module; ensure it matches specifications.
3. Repair or replace damaged wiring or connectors as needed.
4. Apply dielectric grease to prevent future corrosion on electrical connections.
