Pause... THEN starter engages

I have an odd issue with my car in that when it gets cold, the starter doesn't engage immediately when you turn the ignition. I turn the ignition key to engage the starter, there is a pause, and then the starter engages. I'd say above 40 degrees the starter engages immediately, but the colder it gets, the longer it takes for anything to happen. And when I say there is "a pause," I don't mean you can here something spinning or grinding, just nothing, and when it does engage everything works normally.

By the time its 15 degrees outside I'd say the pause is almost 2 seconds. The only thing I can think of is that the cold affects the starter solenoid somehow. Anybody else with this issue? Any ideas?

Battery is new.

Thanks.

the solonoid has a steel bolt in a barrel that forces the starter
to engage when current is applied. it is greased. the grease
can harden/freeze/wear away which might slow or stop its
engagement.

dizaime, except

in temps below 25 my starter makes an awful squeel/squeek like metal on metal. So I think this grease thing may be the problem. Can it be taken apart and greased?

the solonoid is attached to the starter by 3 screws.
take the screws out, pull the solonoid back which
will expose the bolt. (a bolt without threads, a spring,
hook and a metal or nylon piece.) the hook hooks to
the starter engagement lever. 10 minute job on a
240 3 hours on a turbo

Mine does same thing. Posted on it a few weeks ago. Mine did not engage at all when it got down to 15 below a few weeks ago. Now it's gotten better. I assumed it was a bad connection in the starter that got worse as it got colder and the metal contracted. I bought an Autozone replacement but lost the will to install it now that it has improved somewhat.

I'm inclined to think that it is not a sticky solenoid unless the solenoid movement initiates the starter draw. There's no evidence when it happens on my car, that the starter is getting any electricity at all. The lights don't dim. If the starter was getting power but the solenoid sticking, there'd be some evidence that electricity is flowing to the starter.
