Leakage Inspection: Notes
NOTE:
An ultraviolet light must be used to detect the fluorescent dye solution.
- Add UV Fluorescent Tracer Dye (164-R3701 or equivalent specifically for ATF) to the automatic transmission fluid. Use 30 ml (1 ounce) of dye solution for every 3.8 liters (4 quarts) of ATF capacity. Add any additional transmission fluid, designated for this transmission/transaxle, to bring the unit to the correct fluid level.
- Start and run the engine. Shift the transmission through all gears several times to make sure that the fluorescent dye has had time to circulate. Observe the back of the engine, cylinder block and the top of the converter housing part of the case for evidence of fluid leakage. Turn off the engine.
- Raise the vehicle on a hoist.
- Using an ultraviolet light, observe the transmission for possible leaks. Following the leak back to its source point, repair the leak as required.
NOTE:
The leak source will probably be above and/or forward of the actual leak indication, due to airflow and/or gravity.
