Solution

1. Preparation

Gather tools and necessary safety equipment.
Ensure the vehicle is parked on a flat surface and the engine is cool.

2. Raise the Vehicle

Using a jack, lift the front of the vehicle and secure it with jack stands.
Safety Warning: Ensure the vehicle is stable before working underneath.

3. Inspect the Transmission Pan

Locate the transmission pan under the vehicle.
Check for any visible cracks or corrosion on the pan.
If leaks are found, proceed to remove the pan.

4. Remove and Replace Transmission Pan Gasket

Tools Required: Socket set, torque wrench, gasket scraper.
Unscrew the bolts holding the transmission pan in place.
Carefully lower the pan and clean the mating surfaces.
Replace the old gasket with a new one, ensuring it is properly aligned.
Reattach the transmission pan and torque the bolts to manufacturer specifications (typically 10-12 ft-lbs).

5. Inspect and Replace Transmission Cooler Lines (if necessary)

Check the cooler lines for any cracks or loose connections.
If damaged, use the appropriate wrench to disconnect the lines.
Replace with new lines and ensure all fittings are tight.

6. Refill Transmission Fluid

After repairs, refill the transmission fluid through the dipstick tube.
Use the recommended fluid type (usually Toyota ATF WS).
Check the level with the dipstick to ensure it is at the proper level.
