Torque convertor drain on 450SE W3A 040

[STORMINORMAN]

OK, I got the "drain the pan through the dipstick tube" part down, then "drop the pan & replace the filter & gasket.."

My Chiltons shows the convertor drain plug as a bolt on the bottom of the transmission, centered on a grid-like casting.

Am I supposed to just loosen (remove) this bolt and drain what comes out or is there more to it? Is this really just access to the actual convertor drain bolt? If so, how do you get it to line up?

This will be my 1st tranny service and I want to do it right. New fluid, new washers, new filter, new gasket, not too tight, right?

Which transmission filter kit do I use? The 3/4", the "no tube" or the 1" tube kit?

Thanks, again!
