Rear main oil seal leak
 

I have some oil that drips a couple of drops every night from the torque converter. It drips right before it gets to the rubber plug. It looks as though it is coming from in between the engine and the converter. The oil doesn't look like my motor oil. The oil is really dark and kind of milky looking. Oil was changed about 1,000 miles ago.

Would this be the rear oil seal?

I also had my tranny re-built about 3 months ago. Would them removing the tranny have anything to do with the leak?

Thanks for all of the help
