Trans cooling line diagram on sport trac

Hello, first there was no 2000 model Sport Trac. Do you have an all wheel drive model? 2 wheel drive models have a cooler integral to the radiator tank. 4 wheel drive models have one in front of the radiator. As far as a "cooling line diagram" -- I'm not sure what you mean. The cooling lines are original equipment parts; if they are obsolete, you may have to have lines made to match the existing lines, shaped the same way for proper routing. The best picture you can get is in the Ford shop manual, which is printed in publications like www.alldatadiy.com -- and can be accessed there, but there's not much to be learned from that. What are you trying to accomplish?
