Hello, just bought this car used and I have a leak on my U760e transmission that appears to have some gasket sealer on there. It's leaking pretty quickly, it makes a small puddle after sitting a day.

Does anyone know if there is an OEM gasket that is supposed to be there?

 

Appears where the differential housing mates to the trans. Should have paper type gasket. Would be odd this gasket would leak. Are the bolts tight?

Determine if the half shaft seal in the differential housing is leaking and the fluid is moving down the outside of the housing.

Make sure the trans doesn't run out of trans fluid over time.
