2. If low, add the manufacturer-recommended transmission fluid until the correct level is reached.
3. If the fluid is dirty or burnt, proceed to drain and replace it.
Tools Required: Socket set, funnel, transmission fluid pump.

3. Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan by loosening the bolts with a socket set.
2. Carefully lower the pan and drain any remaining fluid into a container.
3. Remove the old transmission filter and replace it with a new one.
4. Clean the transmission pan and replace the gasket before reattaching it.
Tools Required: Socket set, gasket scraper, torque wrench.

4. Inspect and Repair Internal Components

Sub-steps:
1. If slipping persists after fluid change, remove the transmission from the vehicle.
2. Inspect internal components such as clutches and bands for wear or damage.
3. Replace any damaged parts and reassemble the transmission.
Tools Required: Transmission jack, socket set, torque wrench.

5. Reinstall Transmission

Sub-steps:
