Two lines coming out of your trans to cooler .. Both are low pressure but will cause a mess. Fluid should be PINK if you changed it ... easy to notice over engine oil - coolant. The lines are solid. I suspect you have a leak around the trans oil pan..It's common.. go back and re-tighten the 10mm screws.. If you can't tell when they're tight get a torque wrench .. these screws twist off easily.
