1. Locate the transmission dipstick or fill plug.
2. Remove the dipstick or fill plug, wipe clean, and reinsert to check fluid level.
3. If fluid is low, add the recommended type of transmission fluid using a funnel until it reaches the proper level.
4. Recheck fluid level after adding.

3. Replace Transmission Fluid and Filter (if necessary)

Tools Required: Socket set, torque wrench, transmission filter kit (if applicable), drain pan.
Steps:
1. Raise the vehicle safely using jack stands.
2. Place the drain pan under the transmission pan.
3. Remove the transmission pan bolts and carefully lower the pan.
4. Remove the old filter (if applicable) and replace it with a new one.
5. Clean the pan and magnetic pickup (if equipped) to remove debris.
6. Reinstall the pan with a new gasket and torque bolts to the manufacturer’s specifications.
7. Refill the transmission with the recommended fluid type through the dipstick or fill plug.

4. Inspect for Leaks and Test Drive

Tools Required: None specifically, but ensure the vehicle is on a level surface.
Steps:
1. Start the vehicle and allow it to reach operating temperature.
2. Check for leaks around the transmission pan and seals.
3. Perform a test drive to evaluate shifting performance and monitor for any symptoms.
