Once the still left-hand log clutch gets in contact with the second, the next speed equipment is reached. Identical to that, by shifting the ideal-hand Pet dog clutch for the still left and correct, the 1st and reverse gear is attained.
Electronics started to be additional usually utilized to regulate the transmission, replacing mechanical Manage procedures for example spring-loaded valves from the valve system.
