Kenny:Your tranny should be the 3 speed automatic, unless someone has changed it. If it has a cast iron case with a removeable bellhousing, it's the 3 speed. A lot of people have considered it a 2 speed because the shift quadrant has Dr. and Lo. positions, and the trans, when in Dr. takes off in 2nd and shifts once. This is irrevelant to your question of engine removal though.
To remove, you don't have to mark the converter position, since both the flywheel and the converter are balanced separately. Removal is as you say, unbolt everything and pull it out. After separating the engine and trans, measure how deep the converter sits in the bellhousing, and when re-installing the converter to the trans, make sure this distance is the same before bolting it back to the engine so you won't damage the front pump of the trans. You will probably have to turn the converter back and forth to get the splines and drive lugs lined up so that it will seat properly. Drain and refill the trans and converter is a good idea, but you really should remove the pan and clean the pan and screen also. While it is out, if you don't overhaul it or replace all the seals, you should at least replace the front pump seal just to be sure you don't have to pull the trans again soon. I highly recommend a complete tear down and replacement of the internal seals as a precaution.
