Q: My Neon rpms rev to 5000 when I start it. It accelerates on its own. on 2002 Dodge Neon

I just had a transmission replaced approximately 2 months ago. The car does not stop easily and revs very loud when I stop. Its like I am pushing the gas when in park. I started to putter and almost didn't make it home.
