Oil Seals, Replacement
Oil Leakage
First check that leakage is not due to high oil level; oil may be thrown out through vent located on top side of torque converter. Also check for leaks at oil cooler pipes and the test outlet plugs.
With other leakages, clean the transmission and determine if leak can be remedied or if transmission must be removed.
Leaks From Torque Converter Welds
Insert a piece of paper through opening in bottom of torque converter housing. Run engine at idle for a few minutes. Oil spill on paper indicates an oil leak. Replace torque converter.
