My doorbell is no longer working. I thought it was the chime unit, so I bought a new one...as well as a new button. It still does not work. Then figured it must be the transformer, so I have now replaced that. Still nothing. Any thoughts? IU have a 4-wire coming into the doorbell unit.

This sounds like a silly question but btdt...are you sure that you have all the wires going to the correct place and tightly connected? Was there any corrosion on either end when you removed the old to put in the new?
I am not 100% sure the wires to the bell unit are wired in the correct places, but I am 95+% sure that I tried every possible combination given the 3 wires and 3 connection points. I am pretty confident all connections are tightly secured.
I did not detect any corrosion.

Check for voltage coming out of the transformer first thing. It sounds like you lost power to the front of the transformer usually if the button or the chime was acting up you would get a sometimes it works situation.
