How long should i keep the engine running for UV dye to show up? And do i have to rev it or just idle it?

Since I used the fluorescent dye to detect leaks from the power-steering system I had to drive my car around for approx 15 mins to actually see where it was leaking from. At idle I couldn't see any leaks. After the drive the leak was pretty obvious and the UV light picked it up right away.

are glasses included?

Yes. They are an amber/yellow color

Can the kit be used to identify transmission leaks?

transmission leak should b readily identifiable by the red tint already in the fluid to b sure either water blast or at least hose off under hood all oils and then get on fairly clean surface to see if red oil shows up keep in mind u could have more than one leak and some people will put trans fluid in power steering complicating matters
