i bought my car new and haven't messed with it, so everything is all stock. well, my car litterally jumps, it scares me, b/c it hessitates and then suddenly goes, it feels like i got hit in the back sometimes when i take off. i took it to a few transmission places, and they all told me, it's just a hard downshift. anyone know if this is the case, and if so what can i do about it? i was told the only thing i could do was buy a new transmission...

i don't know anything about transmissions, or engines, or cars really, so please don't flame my ass either.
