I'm pretty new to car repair but I've been working on my uncle's 1966 mustang he gave to me for the past year now. I've done everything myself and got it running great after sitting in a garage for 15 years. However, a couple weeks ago i was ran off the road by a guy who was speeding and almost hit me. After I veered off the road my transmission was going in and out of gear and I barely made it home. The next day I tried to drive it and it wouldnt get into gear at all. I'm really hoping it's a simple fix because I find It hard to belive that just veering off the road would completely total my engine. But as I said I am very new to car repair and was hoping some one out there may have some ideas of what could be wrong. Thanks!
