I was buying some more yellow-metal safe transmission oil from a local 32-48 ford resto shop, since I let it leak a little too long (no snow until about early Dec and a couple of times recently where the roads were dry and salt-free) and the last quart I bought from them a month ago was almost emptied when I FINALLy got around to filling the trans last weekend. We got to talking about the bad leak I have from the ball. The green piece here from Greg Roselle's site http://home.earthlink.net/~36bu
