Check the shift cable, make sure it is not loose or seperated from a hold down bracket, also make sure the motor mounts are good. If all is OK, then remove the shift console and inspect the shift mechanisim for broken parts.
The inside of the CC contains a "honeycomb" looking material. This material is strong but subject to overheating (which will melt it) and is usually caused by an rich A/F mixture. It is also subject to impact, that is, if hit hard enough the material will crack and can break off into chunks inside housing causing the rattling noise.
