2. If the fluid is low, add the recommended type of transmission fluid (typically Toyota ATF WS).
3. If the fluid is dirty or burnt, proceed to change the fluid.
4. Remove the transmission pan by unscrewing the bolts (use a socket set).
5. Carefully lower the pan and allow old fluid to drain into a container.
6. Replace the transmission filter if applicable.
7. Clean the pan and magnet (if equipped) before reinstalling.
8. Reinstall the pan with a new gasket, tightening the bolts to the manufacturer's torque specification.

3. Adjust Transmission Linkage

Sub-steps:
1. Inspect the transmission linkage and cables for damage or misalignment.
2. If necessary, adjust the linkage according to the vehicle's service manual specifications.
3. Ensure all connections are secure.

4. Reconnect Battery and Test Drive

Sub-steps:
1. Reconnect the battery terminals.
2. Start the engine and allow it to reach operating temperature.
3. Test drive the vehicle to ensure smooth shifting and operation.
