I used a 1 inch metric hex bolt (I think it is a 17 mm one) put two nuts on
them, spot welded, grinded it smooth. The head of the hex bolt fits in the
drain plug and filler plug. Use this homemade plug with a combination wrench
and draining and filling the transmission fluid is a snap.

I use a big syringe with a plastic tube attached to fill the transmission
fluid.

Now I have to come up with a way to measure 1 centimeter from the fill gap
so that I do not over fill it.
