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. Change Transmission Fluid

Tools Required: Socket set, transmission funnel, drain pan.
Remove the transmission drain plug and allow the fluid to completely drain into the pan.
Replace the drain plug and tighten to the manufacturer’s torque specifications (typically around 30-40 ft-lbs).
Refill the transmission with the appropriate type of fluid (typically Toyota WS ATF) through the dipstick or fill port using a funnel.

3. Replace Transmission Filter

Tools Required: Socket set, screwdriver, gasket scraper.
Remove the transmission pan bolts and carefully lower the pan to access the filter.
Remove the old transmission filter and replace it with a new one, ensuring any O-rings are properly seated.
Clean the transmission pan and install a new gasket before reattaching the pan.

4. Reconnect Battery and Test

Reconnect the negative battery terminal.
Start the engine and allow it to reach operating temperature.
Shift through all gears with the brake applied to circulate the new fluid and check for smooth operation.
