I had my transmission flushed at 61k.mi. I now have 77 k.mi. & my shop, a dealer, says I need it done again Does this sound right? It's a 2002 Buick Century.'Thanks.

This doesn't sound right at all. You should have it done every 30k miles but 16 is a little overboard really. Even then it depends on your driving habits and the environment you live in but 30k is on the safe side of that. Now if they just flushed it out then i would suggest maybe replacing the filter (hopefully they did that with the flush!). If there are any problems with the transmission i can almost stake that it doesn't have to do with the fluid but something else. There is always a chance that the shop that did it didn't do it right so i can't say exactly if it would really NEED it or not. You can check the fluids and make sure that it still looks good. If it doesn't then there is something else wrong causing this (maybe a seal) or the shop didn't properly flush it.

Have a good one!

I have a 1989 Buick Electra with 203,000 miles, and the transmission has never been flushed. If you feel you need to change the fluid and filter at regular intervals, take it to the local fast lube place and save some big bucks. The dealerships charge 2 to 3 times the fair rate for this service. Plus, at a fast lube place, you can wait for your car instead of leaving it for who knows how long.

No it doesn't. If this is the case, they didn't do something the first time.

If you're not having troubles with it, I'd pass on another service. Trans fluid & filter should be done about every 50k or 30k if you do some towing. Having it done every 15k or so sounds like they're selling you something you don't need.
