Hello, I have a Vectra and my problem is that, a few seconds after braking, the car jerks and hits strongly. All the mechanics I have visited recommended me to replace or repair the transmission, but it is rather expensive. What do you think?

Hello, the problem with my vehicle is that, when stopped at traffic light, it purrs continuously. I need to set a gear so that the annoying noise disappears. But since yesterday, gears cannot be changed, or at least they are not registered. I was told it must be the computer that is failing, but I do not know how to make sure that this is the problem and where to buy one. Even more, the interior light has stopped working.
