Just to mate the engine? No way.
Don’t use a load leveler with your hoist. It will hit the top of the firewall with like 1” to go between the engine and trans. I learned that the hard way. Use bolts and chain.
I did it solo. It was a lot of stand up, lay down, but doable. Have a big ratchet read to gently turn the engine as you push to get the converter bolts in their holes. Then send whatever bellhousing bolts you can get, and worry about the uppers last.
As for the trans filter...this is likely an unpopular opinion...but I rarely change mine. I use a filter in the cooling loop. The one in the pan is very coarse media, only catches big stuff. IF you’re using an external filter and that pan filter gets clogged enough with particles to create a pressure Delta, your trans is probably proper ****ed anyway. I change fluid via the cooling hoses every 30,000mi. Got lots of miles on my perfectly functioning tranny with beautiful, clean fluid.
Moving that cat every 100,000mi or so to change the filter and clean the magnet isn’t too bad
