Solution

1. Preparation

Gather necessary tools and parts.
Ensure the vehicle is parked on a level surface with the engine off and cool.
Disconnect the battery (negative terminal) to avoid electrical issues.

2. Locate the Leak Source

Visually inspect the transmission pan and cooler lines for signs of fluid leakage.
If using UV dye, run the engine to circulate the fluid and observe any leaks under UV light.

3. Repair the Leak

For Transmission Pan Gasket Leak:
1. Raise the vehicle securely on jack stands.
2. Drain the transmission fluid into a suitable container.
3. Remove the transmission pan bolts using a socket set.
4. Carefully lower the pan and remove the old gasket.
5. Clean the pan and surface where the gasket sits.
6. Install a new gasket and reposition the transmission pan.
7. Torque the pan bolts to the manufacturer’s specifications (typically 10-12 ft-lbs).
For Cooler Line Leak:
1. Identify the leaking section of the line.
2. If the line is damaged, remove the line using appropriate wrenches.
3. Install a new cooler line, ensuring proper routing and connection.
4. Tighten all connections securely.

4. Refilling Transmission Fluid

Use a funnel to add the appropriate type of transmission fluid (check owner's manual for specifications) through the dipstick tube.
Start the engine and let it run for a few minutes.
With the engine running, shift through all gears to circulate the fluid.
Check the fluid level again and add more if necessary.
