I gotta do my wife's HHR's trans filter and fluid soon. Probably do it when she's due for an oil change.

Read your Owner Manual, under normal service it needs no servicing, ever. Taxicab, Courier etc,. i.e. sitting in traffic all day every day is severe service, not stop & go 2 hours a day.

According to my repair manual, there is a small vent somewhere on top of the transmission which would make sense as air has to get out when the transmission heats up and back in when it cools off. I guess by sealed, GM means no dip stick or drain plug? As many folks have noted, the idea is to have GM do it and since I would imagine their cost for transmission fluid is 10% or less than what we pay, the money is mostly labor.
Even if there is no vent, the fluid will still pour in as the air will get pushed out between the funnel and the threaded hole in the top of the case. As I said, the whole process was easy except for jacking and leveling the car which took the most time.

They don't make hydroflush transmissions anymore.

From the 2011 Owner Manual page 7-5. This is the only reference that I can find relating to changing ATF. Page 6-23 refers to type of fluid. I am assuming that the absence of a manufacturer's recommendation means it is not required, but may be done anytime.
"First Engine Oil Change After Every
80 000 km/50,000 Miles
. Engine air cleaner filter replacement. See Engine
Air Cleaner/Filter on page 6‑21.
. Automatic transmission fluid change (severe
service only) for vehicles mainly driven in heavy
city traffic in hot weather, in hilly or mountainous
terrain, when frequently towing a trailer, or used
for taxi, police, or delivery service. See Automatic
Transmission Fluid on page 6‑23"
Of course, my dealer and every service center I have been to recommends a transmission flush on every visit, regardless of mileage.
