Here's one I had been searching a few years for that only recently turned up. Though it doesn't
actually have any transformation, it had an influence on my younger self all those years ago that might have contributed to my female werewolf fetish. What it has is the build up to an implied TF that never happens, a big tease really, but for it's time and the show it was on I'm surprised it even had anything remotely TF related.
The potential TF tease begins a little after the 8 minute mark.
