These drawings should help when you have to remove or adjust your shift linkages (220D, 240D, 190D and 190E). They will certainly help to get the rods back in the proper locations. If you have shifting problems then check the adjustments. Note the use of a locking pin in the base of the shifter assembly. You can fabricate anything that fits in the hole and keeps the levers aligned.
Problem & Solution
Common among these chassis:
With the shifter lock pin in place, make certain each lever on the transmission is in the centered position (you will feel it click in). Then adjust the length of each rod so both ends fit easily into the levers (with no resistance or binding).
Replace worn or missing rod bushings.
