Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Safety: Disconnect the battery before working on the electrical systems.

2. Check and Replace Transmission Fluid

Fluid Inspection:
- Remove the transmission dipstick and check fluid level and condition (should be reddish and clear).
Fluid Replacement:
- If fluid is burnt or low, drain the old fluid by removing the transmission drain plug.
- Use a fluid pump to refill new fluid through the dipstick tube. Ensure to use Toyota WS transmission fluid.
- Replace the drain plug and torque to the manufacturer’s specification (typically around 10-12 ft-lbs).

3. Inspect and Replace the Transmission Filter

Remove the Transmission Pan:
- Support the transmission pan with a jack if needed.
- Remove the bolts securing the pan and carefully lower it, allowing fluid to drain.
Replace the Filter:
- Remove the old filter and install the new filter, ensuring it is securely fitted.
Reinstall the Pan:
- Clean the mating surface of the pan and the transmission, install a new gasket, and reattach the pan, torquing the bolts to specification (usually around 8-10 ft-lbs).

4. Check for Component Damage

Inspect the transmission for any signs of damage, such as burnt clutches or damaged gears.
If damage is found, disassemble the transmission as needed for repairs.
