Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shorts.

2. Check and Replace Transmission Fluid

Tools Required: Socket set, funnel, drain pan.
Remove the transmission pan bolts using a socket.
Carefully lower the pan and drain the old fluid into a drain pan.
Inspect the old fluid for metallic particles or burnt smell; if present, further internal inspection may be needed.
Replace the transmission fluid with the manufacturer-recommended type (typically Toyota WS fluid).
Reattach the transmission pan with a new gasket, torquing the bolts to the manufacturer’s specifications.

3. Replace Transmission Filter

If applicable, remove the old transmission filter (usually located inside the transmission pan).
Install the new filter, ensuring it is seated correctly.
Reattach the transmission pan with the new fluid.

4. Inspect and Replace Transmission Mounts (if necessary)

Tools Required: Jack and jack stands, wrench set.
Support the transmission with a jack.
Remove the bolts securing the transmission mounts.
Inspect for wear, cracks, or damage.
Replace with new mounts if any issues are found.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Check for leaks around the transmission pan and mounts.
Test drive the vehicle to ensure proper engagement and shifting.
