Exclamation 1996 Mustang Coolant leaking out between engine and transmission

Need Help. Working on a 96 Mustang with 5.0 liter. Leaking coolant out rear of motor. I have checked all top parts and see no leaks. As you pour water into radiator you can visually see it coming out on bottom of the motor where the flywheel is located. I am thinking it could be the freeze plug for the block itself, but it looks as though the transmission will need to be pulled. Has anyone gone through this experience. I have checked the oil numerous times and does not reflect a blown head gasket. No miss on engine when running either. Someone please advise. All help is appreciated.

Are you sure its a 5.0L 96 had a mod motor? 95 was the last year for the 5.0. Sounds like the heater core.

Sorry, you are correct. It is a 3.8 liter. As far as the heater core, there is no leaking at connections to firewall and nothing inside the car that i have noticed. It seems that as you are pouring water in it is coming out as fast. That is why i am thinking rear block freeze plug or possible water jacket up inside the bell housing at block.

Yes I agree, a 6 is not an 8. It is actually a car i am working on for a less fortunate individual. I appreciate the assistance. Since i am not familiar with this car, Where would i be able to find a diagram of the rear engine showing the freeze plugs locations. I have searched eveywhere and all he has is a Haynes manual which as you know is extremely generic. Do i need to go ahead and pull trans to get a better look at the rear block. Trust me i do appreciate the help.
