So I was driving my car this arvo and I stopped at the traffic light only to find that my transmission was tuck in fourth, after a bit of effort I got it into first and managed to pull over but I now have a car stuck on the side of the road with a busted transmission. I can still drive normally in first and I haven't heard anything strange except for a whine in second that has been present since I bought it, it was popping out of gear though if I drove aggressively. Can anyone come up with some ideas about what might've happened?
