Replace damaged components:
- If the leak is from a seal or line, replace the damaged part.
- Use a socket set to remove the old seal or line and install the new one.
- Ensure proper torque settings are followed for any bolts removed.

3. Fluid Replacement

Drain old transmission fluid:
- Place a drain pan under the transmission pan.
- Remove the transmission pan bolts and let fluid drain completely.
Clean the pan and magnet:
- Clean any debris from the pan and the magnet inside the pan.
- Inspect for metal shavings, which may indicate internal damage.
Install new filter (if applicable):
- Replace the transmission filter if the model has one.
- Follow the manufacturer's specifications for installation.
Reinstall the pan:
- Place a new gasket on the pan and reinstall it, tightening bolts to the specified torque.

4. Refill Transmission Fluid

Add new transmission fluid:
- Use the recommended transmission fluid type for the Camry.
- Use a funnel to pour fluid through the dipstick tube.
- Check the level frequently to avoid overfilling.

5. Test the System

Reconnect the battery:
- Ensure all connections are secure before reconnecting.
Start the engine:
- Allow it to reach operating temperature and check for leaks.
Test drive the vehicle:
- Monitor the shifting and any unusual smells or sounds.
