Solution

1. Preparation

Tools Required: Socket set, torque wrench, fluid catch pan, OBD-II scanner, transmission fluid.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal for safety.

2. Identify the Leak Source

Sub-steps:
1. Clean the area around the transmission pan and lines with a degreaser to remove old fluid.
2. Start the engine and let it reach operating temperature.
3. Observe the transmission area to identify the source of the leak.

3. Repair the Leak

Sub-steps:
1. If the leak is from the transmission pan:
  - Remove the bolts securing the transmission pan using a socket.
  - Carefully lower the pan and drain the fluid into a catch pan.
  - Inspect the gasket for damage; replace if necessary.
  - Clean the mating surfaces and install a new gasket.
  - Reinstall the pan and torque the bolts to the manufacturer’s specifications (usually around 10-12 Nm).
2. If the leak is from the cooler lines:
  - Disconnect the lines using a wrench.
  - Replace any damaged lines or gaskets with new parts.
  - Reconnect the lines securely and ensure there are no kinks.

4. Refill Transmission Fluid

Sub-steps:
1. Use a funnel to refill the transmission with the correct type of fluid as specified in the owner's manual.
2. Start the engine and let it run for a few minutes.
3. Check the fluid level again and add more if necessary until it reaches the proper level.
