Solution

1. Preparation

Gather tools and materials.
Tools Required:
- Socket set
- Torque wrench
- Transmission fluid pump
- Oil catch pan
- Rags for cleanup
Safety Warnings:
- Allow the engine to cool before working on the transmission.
- Disconnect the battery before working on electrical connections.

2. Addressing the Leak Source

2.1. Transmission Pan Seal Replacement
- Drain the transmission fluid into an oil catch pan.
- Remove the transmission pan bolts using the socket set.
- Carefully lower the pan and inspect the old gasket for damage.
- Clean the transmission pan and the mating surface on the transmission.
- Install a new gasket and reattach the pan, torquing the bolts to manufacturer specifications (typically around 10-12 ft-lbs).
2.2. Cooler Line Inspection and Repair
- Inspect the cooler lines for cracks or loose connections.
- If found, replace damaged lines with new ones, ensuring tight connections.
- Use the pressure test kit to confirm no leaks after replacement.

3. Refilling Transmission Fluid

Using a transmission fluid pump, refill the transmission with the appropriate type and amount of fluid (check the owner's manual for specifications).
Start the engine and allow it to reach operating temperature, then check the fluid level again and add more if necessary.
