Pray that it's the solenoid. I believe that can be fix without pulling the transmission.

I would try a transmission flush before you spend the big bucks. I've seen it work wonders. I HIGHLY recommend BG brand flush fluids.
There was a service bulitin for those transmissions. It's the second gear cluch assembly. It's defective. I have a 2004 Buick LeSabre it does the same thing but only when it shifts into 2nd gear. It shutters.
