Abstract: A process is provided for the manufacture of a gearshifting or sliding sleeve for the forced synchronization of manually shifted automotive transmissions in which the sleeve is manufactured in the form of two substantially symmetrical partial units and is then processed further into a complete sleeve by means of customary joining methods. This process permits sleeves to be manufactured by means of comparatively low-cost powder metallurgical methods through pressing and sintering, and thus makes it possible to dispense with very cost-intensive machining methods.
