Solution

1. Preparation

Gather necessary tools and materials.
Ensure the vehicle is parked on a level surface and the engine is turned off.
Allow the engine to cool if it has been running.

2. Raise the Vehicle

Use a jack to lift the vehicle safely and secure it with jack stands.
Ensure the vehicle is stable before working underneath.

3. Inspect the Transmission Area

Transmission Pan:
- Examine the pan for any signs of wetness or fluid drips.
- If leaks are detected, check the bolts for tightness; they may require re-torquing to specification.
Cooler Lines:
- Inspect both the inlet and outlet cooler lines for leaks; if wet, these may need replacement.
Seals and Gaskets:
- Check the input and output shaft seals for any signs of leaks. These seals can degrade over time and may need replacement.

4. Clean and Test

If any leaks are found, clean the affected area with a degreaser to remove old fluid.
Once cleaned, run the engine and operate the transmission through the gears while observing for new leaks.

5. Replace Damaged Components

If any damaged seals, gaskets, or lines are found, replace them with new parts.
Ensure to use OEM or high-quality aftermarket parts for the best fit and durability.

6. Recheck Fluid Levels

After repairs, check the transmission fluid level again and top off if necessary.
Dispose of any used fluids or parts in accordance with local regulations.
