The quandry that this symptom presents is trying to decide if its an IMS leak or a RMS leak. An IMS leak is worrisome while an RMS leak generally isn't serious.

First, be SURE that the leak is coming from between the transmission and the engine. My car had a similar leak and even the dealer said that it was either IMS or RMS but the leak disappeared when I replaced the spark plug tubes.

Otherwise, the only way to know what is leaking is to remove the transmission.
