Will a dodge neon 2000 manual transmission fit in a 2000 Plymouth neon?

yes, they are the exact same car. the only difference are the names Dodge and plymouth, which are both owned by Chrysler.

LMAO, WAS THIS A SERIOUS QUESTION?

Depending on your VIN number, they are NOT the exact same. I, for one, have a 2000 PLYMOUTH, and the CLUTCH is VERY different than a dodge. you have to order SPECIFIC parts designated to that very VIN, for example, a hazard relay, has to be OEM, or it's gonna blow your crap.

YES, it will fit.
