Good expression for "things are starting to work"?

Is there a good and meaningful expression for "things are starting to work"? Italians would say "le cose stanno ingranando", where the verb "ingranare" literally translates "to gear". Can it be used in such an expression?

We also say, "Things are starting to come together" or "Things are starting to fall into place".

Cooking (On/With) Gas

to be making good progress and to be likely to succeed.

'We're cooking (on/with) gas. Keep the work coming in like this and we'll meet the deadline.' http://idioms.thefreedictionary.com/be+cooking+on+gas

I propose this as an informal expression, certainly within the UK it is used.
