I have an 1984 190E 2.3 - when I put the car from park to drive it makes a clunk and jerks forward. It also clunks from neutral to drive, and when you take it from any gear and put it in reverse. What could this be? I know there are probably many issues that could cause this, but what is most likely?

The car also jumps out of first into second gear. All of the other gear changes work fine. EX. 1-2 it clunks and from 2-3 and 3-4 it shifts fine.
