Gearbox Scattered ??

Hello guys.Have a problem again with the Clio or with the transmission year 2003. It is a quickshift transmission. He has lost the gears the last time, or has jumped from A and you had to switch, then the car also went out between. But now the problem has become even bigger. It has been stuck in the first gear and can not even start. It has even squeezed the hydraulic fluid out of the tank so that it even now completely completely Is that maybe the hydraulic pump that is defective or more ?? Is there perhaps a fuse for the pump ?? You can switch but you can hear nothing in the engine room only on the display is visible, but it always jumps back into the 1 gear. In the N position I don’t get it either or ?? Have still uploaded a short video as the behavior is on the display. https://youtu.be/q04 gJhGmo-0
