That's been my hunch all along, given that I knew the history of the unit. That is also (in part) why I've left it so long, while I tried driving and snake oil, rather than install another one -- which is almost impossible to find around here... only source wants $900(!) for a used one. I know someone who runs a small VW diesel shop and buys rusty old Mercedes to part them out, but everything he has right now is w126s (or another 240d trans, which I'd like to avoid now doing a second time).

The symptoms you describe (in first gear until very high, then only a second gear) resemble the L (or 2) position by the way. Is the shift rod connected and adjusted correctly? Perhaps the shift rod isn't actuating the valve inside.

Interesting idea, and the shifter is slightly off since the install, but nothing major.
However, if it were in L I would only have 1st, and in S I would have 3rd as well, wouldn't I?

The pin was glued into the modulator?

Sorry don't understand what you mean by glued. You mean was it put back in properly after adjustment? Yes I was there watching.

Did you do the adjustment with a pressure gauge connected to the transmission? You can check three pressures (working pressure, governor pressure, modulation pressure) to see what is going on inside the transmission.

No we haven't done that.
Thanks for all the input, by the way. This transmission peformed very well in the 240d, so I'd like to save it if I can.
