It depends on how you created the transition in. Did you use a Effects Preset, a Text Animation or did you keyframe the motion yourself?
If you keyframed the motion yourself, it's a cinch to create the out-transition.
Effects preset push in but I cant see any up or down transitions out of frame only left or right
Right-click on the title on your timeline and select Show Properties to open the Properties panel.
In the Properties panel, open the keyframe controls. Your preset included keyframes for moving the title into the frame. All you've got to do now is create the keyframes to slide the title off the other side of the frame.
If you don't understand keyframing, have a look at my free article "Basic Keyframing" at Premiere Elements support site Muvipix.com.
