1st: never use a tag or variable as Transition name. Just enter a name in the ‘Pick’ field, en then _select_ the name popped up in the black dropdown.  
Next, save the flow.  
This way you:  
Create the new transition  
You are certain you don’t use an existing transition by accident.

2nd: you’ll need to update f.i. a dim value of a light, using the card WHEN “Transition Y reached a step”.  
You"d select the transition’s name from the ‘Pick’ field dropdown.

As dimvalue tag of that light, select the local tag [`Transitionvalue`]

Flow example:
