Remove the transmission fluid pan (if necessary) to drain the old fluid.
Replace the transmission filter if applicable.
Refill with the appropriate transmission fluid through the dipstick tube using a funnel.
Ensure the fluid level is correct after running the engine for a few minutes and shifting through the gears.

3. Inspect and Replace Transmission Solenoids

Tools Required: Socket set, multimeter, new solenoids (if faulty).
Remove the transmission pan to access the solenoids.
Disconnect the electrical connectors from the solenoids and use a multimeter to test their resistance.
Replace any faulty solenoids with new ones, ensuring proper alignment and connection.
Reinstall the transmission pan and refill fluid as described above.
