Solution

1. Preparation

Tools Required: Jack and jack stands, transmission fluid dipstick, clean rags, flashlight, torque wrench (if reassembly is needed).
Safety Warnings: Ensure the vehicle is on a level surface, and engage the parking brake. Allow the engine to cool before starting work.

2. Raise Vehicle

Use a jack to lift the front of the vehicle and support it securely with jack stands.

3. Clean Area

Clean any visible leaks around the transmission using clean rags. This will help identify the source of the leak more accurately.

4. Inspect Transmission Pan and Seals

Check the transmission pan for signs of rust, cracks, or damage. If the pan is damaged, it will need to be replaced.
Inspect the transmission seals. If they appear worn or cracked, they should be replaced.

5. Repair or Replace Seals

Seal Replacement:
- Remove the old seal using a seal puller or appropriate tool.
- Clean the sealing surface thoroughly.
- Install the new seal using a seal installer or a similar tool to ensure it sits properly.

6. Replace Transmission Pan (if necessary)

If the transmission pan is damaged:
- Remove the bolts securing the transmission pan using a socket set.
- Carefully lower the pan and discard the old gasket.
- Install a new gasket and reattach the pan, tightening the bolts to the manufacturer's specified torque.

7. Refill Transmission Fluid

Use a funnel to refill the transmission fluid through the dipstick tube if any fluid has been lost during the process. Ensure the correct fluid type is used.
