I got in my 2000 CLK 320 and started it went to put it in reverse and
it would not go into reverse.  I turned to car off and stated in again
put it in reverse while my foot was on the brake and it went into
reverse.  Went from reverse to drive and it did shift all still while
by foot was on the brake I then went to put it back into park and the
gear shift would not go back to park as far as it would go was in
nuteral I then turned the car off while in drive and then I was able
to put it in park with the key in.  Any ideas as what needs to be
done.
