Leakage Inspection
Leakage Inspection
NOTE: A 100W/12 Volt DC UV Lamp must be used to detect the fluorescent dye solution.
Dye-Lite(R) ATF/Power Steering Fluid Leak Detection Dye 164-R3701 (Rotunda) is used to detect a transmission fluid leak.
1. Add dye to the transmission fluid. Use one 30.0 ml (1 oz) of dye solution for every 3.8L (4 qt) of transmission fluid. Add any additional transmission fluid, designated for this transmission/transaxle, to bring the unit to the correct transmission fluid level.
2. 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 transmission fluid leakage. Turn off the engine.
3. Raise the vehicle on a hoist.
4. NOTE: The leak source will probably be above and/or forward of the actual leak indication, due to airflow and/or gravity.
Using a 100W/12 Volt DC UV Lamp, observe the transmission for possible leaks. Following the transmission fluid leak back to its source point, repair the leak as required.
External Fluid Leaks:
External Sealing
NOTICE: Do not try to stop a transmission fluid leak by increasing the torque beyond specifications. This may cause damage to the transmission case threads.
The transmission has the following parts to prevent external transmission fluid leakage:
- Gaskets
- Lip-type seals
- O-ring seals
- Seal rings
- Seal grommets
- Seal washers
- Thread sealant

Fluid Leakage in Torque Converter Area
Leakage at the front of the transmission, as evidenced by transmission fluid around the torque converter housing part of the case, may have several sources. By careful observation, it is possible in many instances to pinpoint the source of the transmission fluid leak before removing the transmission from the vehicle.
The paths which the transmission fluid takes to reach the bottom of the torque converter housing part of the case are shown in the illustration. The 5 numbers in the illustration correspond with the 5 flow path steps.
