[V8] Transmission Flush

Standard procedure for "flushing" the V8 tranny is to open the drain, let
it drain out (about a gallon) and install a gallon of new fluid.  Then
drive a bit (I put about 100 miles on) and repeat the procedure.  You want
to do it three times.  Then you'll have mostly fresh fluid and at the
proper level.

If you want to drop the pan and replace the filter, as I understand it, you
 then  bolt it back up, pour in the gallon, drive it some, drain the pan,
pour in another gallon and repeat once more.  Either way, it takes three
