2005 Buick LeSabre Transmission Problems :(

I have been having some trouble with my transmission hard shifting as I accelerate. It's been kind of weird....

2005 Buick LeSabre 185,000

The car sometimes will shift hard when accelerating.

It happened once a few months ago- I had been on the road for hours and it just decided to start doing it. Then when I stopped for gas, it went away as soon as I got back on the road. It didn't do it again for months.

Lately it had been doing it more, but it would be the same thing. It wouldn't start until I had been driving for a bit, then when I shut it off, it would go away immediately.

I had the transmission flushed and cleaned, and now it seems to be doing it more often.

Sometimes I can go an hour and get to where I need to go without a problem, other times it happens 30 minutes down the road. It has never done it immediately after starting my car, it usually takes at least 20 minutes to act up.

Any ideas as to what would cause this? Any help is greatly appreciated.
