Synchronizer Rings

WARNING: This page is about a different car, the 2013 Volkswagen Beetle and 2012 Volkswagen Beetle. However, it is still accessible from the selected car via links, so may be relevant.

Do not interchange them. When reusing synchronizer rings, always install them to the same gear.
Check for wear and replace as necessary.
Check the grooves -arrow 1- on the synchronizer ring -A- and the inner race for flat areas (grooves are worn).

Check taper of the drive gear for grooves and scoring.
Coat the synchronizer ring with transmission fluid and then install.
