Renault

Hello everyone and in advance thanks for the answer
the following tongo a problem with the velocity box changes the chins and rusult that the fourth does not enter

that Renault you have good there is no problem because all the models bring the same 9-11-megane-laguna-kangoo- when I disassemble the boxes before changing the synchronizers I set me if the brains slow down and then I fixed if the teeth are not spent, if so I send it to the turner and make the teeth of the gear and those of the synchronized so that they do not jump. TBN you have to see first if the gear lever is well regulated by
