Zusammenfassung:	A gearshift lever (10) and a method of forming the lever is disclosed. The lever includes a one-piece shaft (12) with a functional end (16) and an operative end (14), the functional end (16) being cold formed to a specific configuration for mechanical cooperation with components auxiliary to the lever. The channel region (18) is provided along the shaft between the functional (16) and operative (14) ends for running electrical wire (20) between the functional and operative ends, and a shaft covering material (32) surrounds the channel region (18) for containing the electrical wire within the channel region. The cold forming of the functional end (16) of the lever reduces the cost of manufacturing the lever. In an alternative embodiment, the shaft of the lever is provided with a hollow bore (18) along the length of the shaft for enclosing the wires. Levier de changement de vitesse (10), et procédé de fabrication associé. Le levier comporte un tube creux d'une seule pièce (12) présentant une extrémité fonctionnelle (16) et une extrémité de commande (14), la première (16) étant forgée à froid dans une configuration adaptée à sa liaison mécanique avec les pièces auxiliaires du levier. Le canal (18) du tube compris entre les extrémités (16 et 14) sert de passage à des fils électriques (20) reliant lesdites extrémités. Une gaine (32) entourant le tube maintient les fils à l'intérieur du canal (32). Le forgeage à froid de l'extrémité fonctionnelle (16) abaisse le coût de fabrication du levier. Dans une autre réalisation, le tube est plein et pourvu d'une rainure (30) longitudinale destinée à recevoir les fils.
