I know this posting was from a while back, but did you ever fix that 'thunk'?

Just curious, because the note, "...adjusted Modulator" caught my eye.

I just recently "adjusted the modulator" on my '81 300TD-T to make my shifts a little more hard. It is very simple, and easy to find.

On the driver's side, just above the AFT pan, there is a 1/2 dollar sized (green on my car) modulator. Pop off the sm

There you will find a very small "T" shaped key. Turn the key 1/4 turn clockwise for harder shifts, 1/4 turn for softer shifts. This has nothing to do with the shift timing, only the softness/hardness.
Current: '91 300TE 4MATIC 317k and climbing...
'81 300TD Wagon 168K "Tank"
'83 240D 216K 4spd manual "Da Bear" (aka best car ever)
