It's leaking again.  A few years ago it started leaking when I tried
to climb an extended grade in D rather than 2 after a day of hot
driving.  Full throttle, ~3200rpms.  I don't do that
anymore.  Anyway, I bought a "snake oil" product called "no leak"
from the Gold Eagle Co. and dang if it didn't work!  So this has been
a cold winter and I haven't driven the van much until a nice little
trip this weekend, maybe 150 miles with some mtn climbing on the way
home.  The leak is not as bad as the time several years ago, but it
is dripping too much to stand.  I'm going to first try this miracle
product on it again.  If that doesn't work, the next step is to
replace that Torque Converter seal.  I've pulled the trans out
before, but what would I need to do to replace that seal, other than
actually replacing it?  Do I need to do anything to the TC mating surface?

Thanks,
Edward
