help please

slm, I have 84 pejo 505, I was going to ankle on holiday, I passed the full bolu, the car suddenly started to shake to shine on its own. I do not make time when I do not press the gas too much, a little 60 km flan my livelihood trembles the car then I went to hard trouble adaptation, then the car was not completely displaced, the gears are passing, but the sounds come from the bottom, the car is working but when I put it in gear, mules and sounds do not move, I would be glad if you can help, thank you

Even though it was past, the vehicle was old. In this forum I do not know whether to remove that vehicle or not. In 95-96 years, we had 82 models of 505 GR 1.7 carburators. I think there is a problem in the driveline of the vehicle. Have you done or had a detailed check?

I wish I could have commented if I had no information, but I wish it would be inexpensive as soon as possible

I'm so devastated because of this car
