Ist it necessary to flush the transmission and engine coolant on this car with 30,000 miles.

Never mind the miles, I think at that age it likely is time (but I don't have the manual that says so).

No

It's probably good enough. I don't like the idea of "flushing" radiators or (especially) transmissions. Draining just the radiator will get rid of mot of the old coolant.

DO NOT let them "flush" your transmission!! Just drain and refill and change the filter if there is one.

Thank you. FYI--I took it to a chrysler dealer yesterday with a coupon that said Cooling system service, drain, replace, $80.00. The writer told me all they do is drain the recovery tank & refill it. I said you gotta be kidding. I said I could suck that out with a vacuum & refill it for a lot less than $80. He then said let me check. He came back and said they will drain the radiator but not the engine block only. Is that the proper way to do that?

That should be fine. You should change the coolant every couple of years but NEVER hook up a transmission to an actual "flushing machine". You can just drain the transmission oil and refill when the factory says to do it (in your owner's manual). You go by the manual, not what the dealer's service writer says.
