What would cause the tranny to clunk and shift hard? on 2004 Mercury Mountaineer

It is AWD. It does not do it all the time. It does not seem to matter whether it is cold or warmed up. It happens most often when you come to a stop and start to drive again. My boyfriend thinks it is usually 3rd gear.
