Yes, any light grease will suffice. I don't like the idea of the anti-seize but as long as you didn't "goop" / slober it on.. I guess it's okay. it's a coating, not a lubricant, it will wash off when in contact with the ATF fluid.

And good choices for the convertor journal, I use the same light grease there also, anything to keep the area lubed while waiting for the startup.

OH.. and welcome to the club! Nice to see you here.
