I apologize if this was asked before but does anyone know where on the internet I can look at and/or purchase replacement shifters for the automatic 2000SE?

 

You can try this place: http://www.autofreak.net/ , or upgrade to a Nissan 2K1 AE shifter. The problem with an aftermarket shifter is many do not have the OD button on it. Plus, the one or two aftermarket shifters which are available (Levoc?) look to be taller than the stock shifter, meaning the end of the shifter will be higher in the air. The aftermarket one's look cool, though.
