Where? Behind the converter? If it is it's either the pump seal or converter seal. How is the pump bushing? Did you install the seal correctly?

No need for silicone. Check the pump bushing and make sure you are using the correct seal. Install it flush and lube the seal. If it isn't going in there tight something is wrong.
