Condition
Some customers may comment about an oil leak. Upon further investigation, the technician may find a transmission oil leak at the transmission converter
housing or transmission case to housing, at the gasket, or at the rear lower engine oil pan bolts.
Correction
1. Verify that the transmission has a fluid leak. Refer Fluid Leak Diagnosis Dye and Black Light Method in SI. Carefully inspect with the black light to
check the axle seals. Make sure oil from the axle seal leak isn't running down the case and ending up on the case to housing split line.
2. Inspect the converter housing to oil pan weep hole and the two lower rear engine oil pan bolts with a black light. If either location shows leakage with
dye, the source is most likely the torque converter hub seal.
3. Remove the transmission. Refer to Transmission Removal in SI.
4. Once the transmission is removed from the vehicle, inspect with the black light to ensure that the leak is coming from the torque converter fluid seal.
Install a new seal assembly, GM P/N 24249775. Refer to Torque Converter Fluid Seal Replacement in SI.
