I borrowed my mom's 1996 Dodge Caravan, and without warning, the darn thing
stopped driving.  I had it towed home, and realized a steady stream of
transmission fluid in the ground.  My friend told me the front seal was
leaking, so I thought oh well, I'll put more in and drive it, until the shop
can take it on Tuesday.  Well, low and behold, it pours out on the groud as
fast as I pour it in there.

Is there perhaps a (loose screw) drain plug on this van?  Or is it leaking
out because I had the engine off when I poured it in?  

My sister has a transmission leak on her Sephia Kia, and she pours in a quart
every 150 miles and keeps driving.  It's been nearly a year and she is still
going.
