Solution

1. Preparation

Tools Required: Socket set, wrench set, transmission fluid dipstick, clean rags, OBD-II scanner
Ensure the vehicle is on a level surface and parked securely.
Disconnect the battery to avoid any electrical issues.

2. Identify the Leak Source

Sub-steps:
- Visual Inspection: Check all visible transmission lines and seals for any signs of leakage.
- Transmission Pan: Inspect for cracks or damage. If necessary, clean the area around the pan to better identify the leak source.
- Fluid Check: Use the dipstick to check fluid levels and condition.

3. Repair or Replace Seals/Lines

Sub-steps:
- Seal Replacement: If leaks are found at the seals, use a seal puller to remove the old seal and install a new one, ensuring proper alignment.
- Line Replacement: If damaged transmission lines are identified, use a wrench to disconnect them and replace with new lines, ensuring tight fittings.
- Pan Gasket Replacement: If the transmission pan is leaking, remove the pan by unscrewing the bolts, clean the mating surfaces, and install a new gasket before reattaching the pan.

4. Refill Transmission Fluid

Sub-steps:
- Use a funnel to refill the transmission fluid through the dipstick tube with the manufacturer-recommended fluid.
- Check fluid level again after refilling to ensure it’s within the acceptable range.

5. Final Checks

Sub-steps:
- Reconnect the battery.
- Start the engine and allow it to reach operating temperature.
- Shift through all gears to ensure proper operation.
