1. Thoroughly clean the suspected leak area with a solvent.
2. Remove the converter shield, if required.
3. Apply an aerosol type powder such as foot powder to the suspected leak area.
4. Start the engine and run at fast idle.
5. Repair leaks and recheck as necessary.
- Identify the type of oil (transmission fluid contains a red dye).
- Leaking oil is generally carried toward the rear of the car by the air stream.
6. Drive the car approximately 15 miles to warm up unit to operating temperature 88° C (190° F).
7. Inspect the car for leaks with the engine running.
