I just started noticing drops of tranny fluid on the driveway. I crawled underneath looked around but did not see leaking at any of the seals. I tightened up the pan bolts a little but that does not seem to be the problem. I am suspecting the cooling lines where they mount to the bellhousing but it not real obvious. What is the best way to determine if the leak is in these lines and how to repair them? Or just replace them? What size are the lines? Thanks Dan
