95 lumina 3.1 115K miles. This car mostly sits idle. When I started it last it was dumping out transmission fluid from what I could tell was a line coming from the tranny to the trans cooler? or radiator. What I am wondering is does it hurt the trans if the car is running but not in motion with no fluid in it? Its a good runner but I need to replace brake lines as well. not sure if it is worth it?
