My truck overheated and was steaming from the hood. It now leaks coolant, whether the engine is on or off. The leak appears to be coming from the transmission area, but it cant be seen from either the top or bottom. Any ideas?

First check just under where the heater hoses go into the firewall. If coolant is draining from the 4" rubber tube that's hanging down, suspect a leaking heater core. If you can only see the coolant coming from the bottom, front of the transmission, suspect a corroded core plug at the back of the engine block.
