W124 can't select lower gears

[av12ram]

Hi everybody, I went to see a 1995 e320 coupe today and noticed that the gear would go into drive but wouldn't go across into the lower gears; there is a black object which obstructs the gears to go down. its something i noticed on another car and was wondering what this problem was. I have a picture of another car with the same problem. I don't know much about the 124 series so if anyone can shed any light it would be much appreciated.
Regards

its the switch selector from 4 to D on the 5 gear auto transmission, it's a little tough when it is in a good shape.

Thanks. I posted this a little while back before I bought the car and I was being a bit of a noob :fail thanks anyway.
