I've opened the wall behind my bathroom sink and vent stack. I am seeking estimates to attach new he Maytag washer. How and where do I attach outflow hose to the vent stack without causing water in bathroom sink and/or toilet to be sucked out or forced in at high pressure?

Whoever gives you the estimate will know how to install the drain and provide proper venting so it does not happen.

Don't just pick the cheapest estimate. And get the permit included in the quote.

You can't attach ANY drain to the "vent" stack, but if there is an existing bathroom, then there is a drain pipe somewhere.

That is ONLY true, if the code does not allow "wet venting".

Your code allows wet venting a washing machine?

you can not wet vent nor wet vent thru a washing machine drain.
if you tied the washer into the stack above all other properly vented fixtures, the washer would be stack vented.

Yes, and done it hundreds of times, as long as the washer is BELOW the sink's connection.

But then you would have a "major over a minor" situation which could cause siphonage of the sink traps.
