Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the negative battery cable to avoid electrical shorts.

2. Check Transmission Fluid

Locate the transmission dipstick and remove it.
Wipe clean, reinsert, and remove again to check the fluid level.
If low, add the recommended transmission fluid (Toyota ATF WS) until the proper level is reached.

3. Replace Transmission Fluid and Filter

Tools Required: Socket set, wrench, transmission fluid pump, fluid catch pan.
Place a fluid catch pan under the transmission pan.
Remove the transmission pan bolts and carefully lower the pan to drain fluid.
Remove the old filter and replace it with a new one.
Clean the transmission pan and replace the gasket.
Reinstall the pan, torquing the bolts to the manufacturer’s specifications (usually around 10-12 ft-lbs).

4. Inspect and Adjust Linkage

Check the shift linkage for any signs of wear or misalignment.
If misaligned, adjust the linkage according to the service manual specifications.
Ensure all clips and fasteners are secure.

5. Reconnect Battery and Test Drive

Reconnect the negative battery cable.
Start the engine and allow it to warm up.
Perform a test drive to verify proper shifting and monitor for any warning lights.
