Tools Required: Transmission funnel, clean rag.
Steps:
1. Locate the transmission dipstick or fill port.
2. Remove the dipstick, wipe it clean, and reinsert it to check the level.
3. If low, add the recommended transmission fluid (check owner’s manual for specifications).
4. Recheck the level after adding fluid.

3. Inspect and Replace Transmission Filter

Tools Required: Socket set, torque wrench, transmission fluid container.
Steps:
1. Drain the transmission fluid by removing the pan bolts.
2. Carefully remove the transmission pan to access the filter.
3. Replace the old filter with a new one, ensuring it is seated correctly.
4. Clean the transmission pan and replace the gasket.
5. Reinstall the pan and torque bolts to manufacturer specifications.

4. Test and Replace Transmission Solenoids (if necessary)

Tools Required: Multimeter, socket set.
Steps:
1. Disconnect the battery to avoid electrical shorts.
2. Locate the transmission solenoids based on service manual instructions.
3. Use a multimeter to test solenoids for proper resistance.
4. Replace any faulty solenoids with new ones.
5. Reconnect the battery and clear any diagnostic codes.

5. Road Test

Tools Required: None.
Steps:
1. Start the engine and allow it to reach operating temperature.
2. Shift through all gears while stationary, then perform a road test.
3. Monitor for any delayed engagement or abnormal shifting.
