Hello, i have a little question for the techs of this forum. I was driving along today, when i went to drop my car into second from third, There was a crunch, then a loss of drive. I rolled to the side of the road to see what i had killed, but then realised i still had some drive. I then limped the car back to my home with it making an really bad knocking/rattling noise. My first assumptions was that the driveshaft or CV joint had died, as it was the same type of noise. But looking at the driveshafts and the joints, I cant feel any movement or play in them. Am i looking at a new gearbox here, or something different?

Thanks.
