Abstract

L'invention concerne une soupape de réglage de montée de vitesse dans une transmission automatique. La soupape 1 de réglage de montée de vitesse, comprenant un tiroir mobile 3, est associée à la chambre 170 de commande de relachement d'un second frein 106, et à une soupape 136 de temporisation de passage entre la seconde et la troisième vitesse. L'invention permet d'éviter l'emballement du moteur dans une transmission automatique lors du passage de la seconde en troisième vitesse.
