- Replace the drain plug and torque it to the manufacturer's specifications.
- Refill with the recommended transmission fluid through the dipstick tube, ensuring not to overfill.
- Start the engine and cycle through the gears to circulate the new fluid.

3. Replace Transmission Filter

Sub-steps:
- Remove the transmission pan (if necessary) to access the filter.
- Unbolt and remove the old filter from the transmission.
- Install the new filter, ensuring it is seated correctly.
- Reattach the transmission pan with a new gasket, torquing the bolts to manufacturer specifications.

4. Inspect and Repair Electrical Components

Sub-steps:
- Use a multimeter to test the transmission solenoids for continuity.
- Replace any faulty solenoids or wiring harnesses.
- Clean any corrosion from connectors and secure them tightly.

5. Reconnect Battery and Test Drive

Sub-steps:
- Reconnect the battery and clear any error codes using the OBD-II scanner.
- Test drive the vehicle to evaluate the transmission's performance and ensure proper shifting.
