shift solenoid

I need to know what shift solenoid your talking about?Please explain what is going on with your car so i can help you with it.

I'm guessing its the transmission one

Here's the problem you have a line pressure,tcc,2nd,3rd,and 4th transmission solenoid's.That's why i asked you what solenoid?Also if you could please explain to me what is the problem with your car it might not even be a bad solenoid.I'm a factory trained saturn tech so i could really help you with this problem.Let me know so i can help you out.

Well when I am driving my car the shift gets stuck up around the 3 when I'm going from 35 to 55. It makes a buzzing noise when it does that but only when I first get on the highway. When I'm on local streets it mis fires and makes a clunking banging noise when I try to pick back up to speed after coming to a coomplete stop.

Sound's like you have a few problem's.SO do you have a delay before it goes into reverse?Also does it ever shift hard when changing gear's?

Yes to both

Do you have a any trouble code's in your computer?It sound's like you have a pressure issue inside your transmission.If you want to fix it yourself you will need tools socket ratchet air compressor etc.You will also need a transmission pressure gauge set with the adapter's.Otherwise it will cost a lot to have a shop fix it.Are you good at fixing car's?
