Sub-steps:
- Locate the transmission dipstick (if equipped) or access the fill plug.
- Pull the dipstick, wipe it clean, and reinsert it to check the fluid level.
- If low, add the appropriate type of transmission fluid (consult the owner’s manual for specifications).
- If fluid is burnt or contaminated, proceed to replace it.

3. Replace Transmission Fluid and Filter

Sub-steps:
- Drain the old transmission fluid using a drain pan.
- Remove the transmission pan (if applicable) using a socket set, taking care to remove all bolts and gently pry it off.
- Replace the transmission filter according to the manufacturer's specifications.
- Clean the transmission pan and replace the gasket.
- Reinstall the pan and refill with new transmission fluid.

4. Inspect and Repair Transmission Components

Sub-steps:
- If fluid condition is good but the vehicle still does not move, remove the transmission from the vehicle (may require a transmission jack).
- Inspect internal components such as clutches and bands for wear.
- Replace any damaged internal parts as needed.

5. Reassemble and Test

Sub-steps:
- Reinstall the transmission, ensuring all bolts are tightened to the manufacturer's torque specifications.
