    2000 model years can be tricky because early ones have externally balanced cranks and later half uses internal balancing. A way you could check is the harmonic balancer on your crank pulley. My 99 has external balancing so it has a weight on it. See picture

    Mid-00 and earlier have a weight cast into the back of the flywheel. For an automatic, the weight is welded onto the flexplate. If you are replacing a flywheel, I would not trust anything aftermarket. There's been plenty of post on here about bad vibrations after replacing a clutch and pressure plate as parts companies apparently aren't really balancing anything anymore. I bought a Luk flywheel once but after looking at it, I noticed there were no "balance" holes drilled anywhere in it. Highly doubt it was just perfectly balanced after being cast... I took it back and bought a used OEM off of ebay and then took that to a machine shop to get resurfaced. I wanted to get it balanced but most machine shops can't balance a weighted flywheel.
