Instead of a turkey baster, go to Wal-Mart or some such place and go into
the sporting goods section.  They have a pump for a few bucks that you can
screw into the top of a gallon oil jug.  The outlet has a hose on it which
you stick into the tranny, then you pump up and down on the pump in the top
of the bottle.  These are designed and sold for people who are doing oil
changes on outboard motors.  I've used them for years for doing my trannies.
