Having troubles transferring from Modal to Falsetto?

I can ascend from Vocal Fry to Modal pretty good I think, but there is one part where I just loose my voice before I go into Falsetto then I can go pretty high in Falsetto. Does anyone have any exercises to help me smooth that gap between Falsetto and Modal? Or some suggestions on how I can get better? I think I've got a good Vocal range but that one gap makes me just angry at my Modal.
