There is no clutch with your car, just the torque converter which is bolted to the flywheel. If oil gets on it, no big deal.

I would check the carrier that bolts to the engine block that holds the rear main seal. It may have lost it's seal to the block, oil will pass the carrier and seem like you have a rear main leak, but actually not.

Also check the block where the front motor mount braket bolts, on some the block will crack causing an oil leak that will run to the pan rail then the oil will follow around to the area where the pan and the rear main seal's carrier is and it could be misinterpreted as a leak from the rear main.
