Sub-steps:
1. Remove the transmission dipstick and check the fluid level.
2. If the fluid is low, add the recommended type of transmission fluid (refer to the owner's manual for specifications).
3. If the fluid is dirty or burnt, proceed to drain the old fluid.
4. Place a drain pan under the transmission and remove the drain plug; allow fluid to completely drain.
5. Replace the drain plug and tighten to the specified torque (consult service manual for torque specification).
6. Fill the transmission with new fluid using a funnel, ensuring the fluid level is correct.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan (if applicable) by loosening the bolts and allowing any remaining fluid to drain.
2. Remove the old transmission filter and dispose of it.
3. Install the new transmission filter, ensuring it is seated correctly.
4. Clean the transmission pan and reattach it with a new gasket if necessary, tightening bolts to the specified torque.

4. Test Drive and Monitor

Sub-steps:
1. Reconnect the battery.
2. Start the engine and allow it to reach operating temperature.
3. Test drive the vehicle to ensure proper shifting and that slipping has been resolved.
