A833 to bell... gasket?

(Project car) I just installed my transmission Into the bellhousing. It went remarkably well. I used my old motorcycle jack and an old watercraft life jacket to stabilize the trans on the Jack.

I used threaded mounting posts at the top and light taps with a rubber mallet. Slipped right in, 1 mm at a time.

When I was almost finished I thought... wait, is there supposed to be a gasket between the trans and the bell?

I’m thinking ‘no’... and I can’t find one in the manual, nor any sold in any gasket kits, but some confirmation on this would be grand.

Thanks!
