Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface.
Set the parking brake and wear safety gloves and goggles.

2. Visual Inspection

Tools Required: Flashlight
Check for any visible fluid pooling under the transmission.
Use a flashlight to inspect hard-to-see areas around the transmission and under the vehicle.

3. Check Transmission Fluid Level

Tools Required: Transmission fluid dipstick
Remove the dipstick, wipe it clean, and reinsert it to check the fluid level.
If low, add the appropriate Toyota transmission fluid until the level is within the marked range.

4. Inspect Transmission Pan and Seals

Tools Required: Socket set, torque wrench
Remove any underbody covers if necessary to access the transmission pan.
Inspect the transmission pan for signs of leaks; if leaking, replace the gasket.
Inspect around the seals for any signs of fluid; replace seals if damaged.

5. Examine Cooler Lines

Tools Required: Wrench set
Inspect the transmission cooler lines for any cracks or loose fittings.
Tighten any loose connections. If damaged, replace the lines.

6. Conduct Pressure Test (if applicable)

Tools Required: Transmission pressure gauge
Connect the gauge to the transmission test port.
Start the engine and check for proper pressure readings; low pressure may indicate internal leaks.
