Solution

1. Preparation

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

2. Check and Replace Transmission Fluid

Tools Required: Funnel, fluid pump, transmission fluid (Toyota WS fluid).
Remove the transmission fluid dipstick and check the fluid level.
If low, add the correct type of transmission fluid until it reaches the recommended level.
If the fluid is burnt or contaminated, proceed to replace it.

3. Replace Transmission Filter (if applicable)

Tools Required: Socket set, transmission filter kit (if applicable).
Remove the transmission pan bolts carefully.
Lower the pan and allow fluid to drain into a container.
Remove the old filter and replace it with a new one from the kit.
Clean the transmission pan and replace the gasket before reattaching.

4. Inspect and Adjust Transmission Linkage

Tools Required: Wrench set, screwdriver.
Visually inspect the transmission linkage for any loose or damaged components.
Adjust the linkage if necessary to ensure it is properly engaging the transmission.

5. Check Transmission Solenoids

Tools Required: Multimeter.
Disconnect the transmission solenoid connectors.
Measure the resistance across the solenoid terminals using a multimeter.
If readings are out of specification, replace the faulty solenoid.
