I have a 2000 chevy Astro awd that the transmission cooling lines have a bracket that holds the lines to the oil pan. This bracket rubbed holes in both of the lines. If my wife had not seen the fluid on the garage floor when she backed out, the transmission would have burned up. The transmission line has a one inch gash where the bracket held the transmission lines.
