I recently just retired , i was put on tdrl. I had 67.5 days of leave saved up. I was not allowed to use any of my leave, i was forced to sell back 60 days, i just lost the 7.5. hope this helps, i retired 11 july. By the way, my command wanted to let me take as much leave as possible, but our AFPC came down and said no leave period. Not sure how it works in your branch.
