c-4 leaking fluid

hello all.

i have hot rod c-4 in my fox. it has all the stuff ati makes for a c-4.

after i run the engine there is about a pint of tranny fluid on the ground and for the life of me i cannot determine where it is coming from.

the bellhousing and torque converter are dry as is the supply and return line plumbing. the vent port on top of the front near the bellhousing is connected to a catch can and is dry as well.

there is a small drip coming from the pan (cork gasket that needs replaced)

could there be pressure in the pan area pushing out the fluid when running?

i haven't run the car on jack stands and physically looked while it was started as i'm a bit leery of crawling under a running car with solid motor mounts sitting on jack stands.

any ideas?

thanks, rob.
