Default Extra sealer?

Hi everyone

I'm almost finished putting the my transmission case back in place.

Is it better to smear some ATF sealer (Permatex) as an 'extra' on these covers?
I have the new O-rings installed (not visible in the picture).

They came of without any sealer. Just the old (and brittle) o-rings.
The manual says nothing about it, but there are a lot of guys on youtube that do this as an 'extra' it seems...

Do it, or not do it?

Just guessing, an Automatic transmission? I don't recognise any of the bits in your pic's and you mention ATF.
So I'll run with that.
I am no automatic transmission expert by any means.
I am however a mechanic. One who really doesn't like come backs. Automatic transmissions have fluid under a lot of pressure in various places. And your transmission case isn't brand new anymore. So, a thin smear of extra sealant to help compensate for old less than perfect gasket surfaces sounds like a very good idea. Making certain of course not to accidentally block off holes or passages that need to remain open. A THIN smear is key here.

I don't know about those parts shown if they have pressure behind them or not.

But on the pan gasket and the gasket between tail-shaft housing and main case I would recommend a product from Permatex.
Its ATF sealant, RTV, small tube. It is truly ATF proof where not all Permatex products are.
However, in Belgium it may not be accessible.
