On 4 April 1975, all pneumonias were enclosed by a month, leaving to the population without the already as indispensable means of transport. On May 28 of the same year, and without having reached any agreement, the Governor ordered the pea that return all permits to be cancelled; on the other hand delivered temporary Union permits to make work them and thus starts a new stage in the history of the pneumonias. They had the need to appoint an administrator to manage and be made responsible for the operation of the Union, the work they did was so bad that having begun with 110 pneumonias in little time alone there were 24. His next step was to leave the Union handled by itself. And so we move to another phase in the history of transportation in Mazatlan. They made some changes and modifications to the original model, trying to preserve its basic and important characteristics, for example, the 3 wheels were replaced with 4 making it more stable, Cushman chassis was changed by Volkswagen to lower their cost of production.
