In the October 2003 Transmission Digest magazine, there is an article discussing the 2000 syncro rings for the Dodge NV5600 6 speed verses the 20001 on syncro rings. The early rings are no longer available and you need to replace the early gear and early syncro rings together as a set with the 2001-on parts. Parts identified above with (*) are the ones you will need for the upgrade. Purchase these parts (*) as a kit along with syncro rings and take a 10% discount.
