How much came out? Was engine turned off immediately upon lines breaking or was car driven a while? Was tranny empty when noticed?

I drove about 500 feet when they broke and parked it and never cranked over engine since. i towed it home and yes there still it tranny fluid in tranny i wanna say i lost about half a quart to a quart.

I would not be concerned. You don't have an issue. Replace lines and top off fluid.

I had this happen to a customer who I had replaced her radiator and it had tranny lines going into it. They looked and felt good but the next day she drove it in leaking trans fluid. I am going to estimate she lost 2 quarts. She told me her tranny shifted better after I replaced the line and topped off fluid.
