Solution

1. Preparation

Tools Required:
- Funnel
- Transmission fluid dipstick
- Clean rags
- Torque wrench (if applicable)
Safety Warnings:
- Ensure the vehicle is on a level surface.
- Allow engine to cool before checking or adding fluid.

2. Check and Add Fluid

Locate Dipstick: Open the hood and locate the transmission dipstick, usually near the back of the engine bay.
Remove and Clean Dipstick: Pull the dipstick out, wipe it clean with a rag, and reinsert it fully.
Check Level: Remove the dipstick again to check the fluid level; it should be within the markings on the dipstick.
Add Fluid if Necessary:
- If the fluid level is low, insert a funnel into the dipstick tube.
- Add the recommended transmission fluid (typically Toyota Genuine ATF WS) slowly, checking the level frequently to avoid overfilling.
Recheck Fluid Condition: After adding, check the fluid's color and smell again to ensure it is in good condition.

3. Inspect for Leaks

Visual Inspection: Look for any wet spots or puddles under the vehicle, especially around the transmission pan and cooler lines.
Tighten Connections: If leaks are found, check and tighten any loose bolts or connections.
