Sounds like some sort of automatic transmission problem.

There could be many reasons why a tranny slips. here are a few below. when was the last time you changed the fluid? also, have you checked to make sure you are not low on fluid?

It sounds like the transmission is slipping, so I would suggest that you drive–a.s.a.p.–to an _independent_ trans shop ( **NOT** a chain-run joint like AAMCO, Lee Myles, Cottman, or Mr. Transmission) for diagnosis. With any luck, it will be a more minor repair, but you have to be prepared for the news that you need a transmission overhaul.

Based on the age of your Buick, it should have had the trans fluid changed at least 5 times over the years.  
Have you done that?  
If not, that is a likely cause of your trans problems.
