Methods for Locating Leaks
General Method
- Verify that the leak is transaxle fluid.
- Thoroughly clean the suspected leak area.
- Drive the vehicle for approximately 25 km (15 mi) or until
the transaxle reaches normal operating temperature of approximately 88°C (190°F).
- Park the vehicle over clean paper or cardboard.
- Turn the engine OFF and look for fluid spots on the paper.
- Make the necessary repairs to correct the leak.
Powder Method
- Thoroughly clean the suspected leak area.
- Apply an aerosol type powder, such as foot powder, to the suspected leak
area.
- Drive the vehicle for approximately 25 km (15 mi) or until
the transaxle reaches normal operating temperature of approximately 88°C (190°F).
- Turn the engine OFF.
- Inspect the suspected leak area and track the leak path through the powder
to find the source of the leak.
- Make the necessary repairs to correct the leak.
Repairing the Fluid Leak
Once you have located the leak point, determine the source of the leak. The
following list describes the potential causes for the leak:
| • | Fasteners are not tightened to specification. |
| • | Fastener threads and fastener holes are dirty or corroded. |
| • | Gaskets, seals, or sleeves are misarranged, damaged, or worn. |
| • | Gasket surfaces or seal bores are damaged, warped, or scratched. |
| • | Loose or worn bearings can cause excess seal or sleeve wear. |
| • | The case or the components are too porous. |
| • | The fluid level is too high. |
| • | The vent is damaged or the vent tube is damaged. |
| • | The fluid contains water or coolant. |
| • | The fluid drain back holes are plugged. |
