It seems I need a special tool to remove the clamp that holds the rubber
tube to the steel cooler. which kind of tool do I need?
If its a late model Taurus/Sable (around 98 and up) its the lower line. See if you have the type of fitting that has plastic tabs you squeeze to pull the line out. If not, you may need the tool for it. If it is a late model, remove the lower line, attach a rubber hose over the end of the line. Put the end of the hose in a bucket that holds at least 16 qt. Start the engine and watch the fluid come out of the hose. When the steady stream starts to trickle shut the engine off. Fill the trans. with 8 qt. of fluid. Start the engine again and run it until the fluid trickles and shut the engine off. This should take 1-3 min. Now reinstall the trans. line, fill the trans.with 4 qt. of fluid, start the engine and recheck the fluid. You just leave the trans. in park when you do the procedure. If you have any more questions, please include the year, model, engine, and trans. type on your next post.
