Leakage Inspection

Leakage Inspection









NOTICE: Do not try to stop the fluid leak by increasing the torque beyond specifications. This may cause damage to the case threads.

Use the following chart to inspect and correct any external transmission fluid leaks.

External Transmission Fluid Leaks:

External Sealing

The transaxle has the following parts to prevent external transmission fluid leakage:

- Gaskets
- Lip type seals
- O-ring seals
- Seal rings
- Seal grommets
- Thread sealant

External Sealing










Transmission Fluid Leakage in Torque Converter Area

Leakage at the front of 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 a leak before removing the transmission from the vehicle. The paths which the transmission fluid takes to reach the bottom of the torque converter housing are shown in the illustration. The 5 numbers in the illustration correspond with the 5 flow path steps.











Leak Check Test With UV Lamp

Dye-Lite(R) ATF Steering Fluid Leak Detection Dye 164-R3701 or equivalent (specifically formulated for ATF) is used to detect a transmission fluid leak.

1. Add dye to the transmission fluid. Use 30.0 ml (1 oz) of dye solution for every 3.8L (4 qt) of transmission fluid.

2. Start and run the engine until the transaxle reaches its normal operating temperature. Observe the back of the cylinder block and top of the torque converter housing for evidence of fluid leakage. Raise the vehicle on a hoist and run the engine at fast idle, then at engine idle, occasionally shifting to the DRIVE and REVERSE ranges to increase pressure within the transaxle. Observe the front of the flexplate, back of the cylinder block (in as far as possible), and inside the torque converter housing and front of the case. Continue running the engine until fluid leakage is evident and the probable source of leakage can be determined.
