Motor Mount Bolt Removal

Before I pull the engine, does the trans need to be supported in any way? I haven’t removed anything holding the trans like the mount or any braces but I figured I’d still ask just to be sure. Thanks everyone!
Yes, pull the starter, dust shield, flex plate to converter bolts, strut braces from engine to bell housing, support the transmission with a block of wood on a floor jack under the trans pan, then remove the bell housing bolts. Once the engine is out, and if you need to move the car around, strap/wire the transmission up close to the firewall and run a bracket across the bell housing to prevent the converter from coming out. You may want to install a new converter seal while your at it, but, do that right before you re-install the engine. You can see why it's better to pull (drop) the engine and trans together along with the K-member and suspension if this is going to be a restoration.
