"Transit" plus "ion" crates the noun "Transition".

That North American slang has recently grown to include "transitioning" doesn't mean that we all should follow rules in our STEM fields, but discard them in our speech and writing.

I think our backgrounds are affecting our opinions here. As an English major and high school English teacher, I think that using the word "transitioning" is perfectly fine. Language is fluid and over time some words become more appropriate to use, like "transitioning" (IMO). I don't see it as slang but as the adaptation of language to fit modern communication. At one point, until Shakespeare invented it, the word "dislocate" wasn't proper English either. Now it's accepted as a medical term. But, I see your point and leave it up to those using the flyer to proceed as they believe best.
