my tranny cooling lines broke on my 98 Pontiac Bonneville once i replace them and add tranny fluid. whats the probability of my tranny being dead or slipping/failing

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.

Thanks buddy ill replace lines and top off. have a great weekend.

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.
