Are you fixing brightness-contrast one clip at a time ... or trying to keyframe brightness-contrast changes over a different adjustment layer with the transition? I'm puzzled.
What effects have you applied to the first AL?
Position and Rotation keyframes

If you have just position and rotation keyframes on an AL they wont work (actually they work but you are not seeing anything of it).
Put them on the clips themselves.
Use an AL just for the grading.
