Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and engage the parking brake.
Disconnect the negative battery terminal for safety.

2. Check and Replace Transmission Fluid

Sub-steps:
1. Remove the transmission dipstick and wipe it clean.
2. Insert the dipstick back into the tube and remove it again to check the fluid level.
3. If low, add the recommended type of transmission fluid (Toyota WS).
4. If the fluid is dark or burnt, drain the old fluid using a drain pan.
5. Replace it with new transmission fluid, ensuring the correct amount is filled.

3. Inspect and Replace Transmission Filter

Sub-steps:
1. Remove the transmission pan bolts using a socket wrench.
2. Carefully lower the pan to avoid spilling fluid.
3. Remove the old filter and install a new one, ensuring it is seated properly.
4. Clean the transmission pan and magnet, then reinstall the pan with a new gasket.

4. Check Transmission Components

Sub-steps:
1. Inspect the transmission bands and clutches visually for wear.
2. If any components show signs of wear, replace them as necessary.
3. Adjust the bands if applicable, following manufacturer specifications.

5. Reassemble and Test

Sub-steps:
1. Reconnect the negative battery terminal.
2. Start the engine and allow it to warm up.
