Re: [MBZ] 1982 240D Shifting
Kevin, if you have the manual look up 14-050 for the 123.123 (240D). That has both the older and the newer 81 on picture description and vacuum diagrams for the 240D. If you don't have it let me know and I will try to send it to you.

Re: [MBZ] 1982 240D Shifting
Yours may not be equipped as my 78 was, but mine had a rod running across the Valve Cover then to the R. side of the tranny . at the tranny end (or perhaps behind the engine/over the tranny there is a pressed in bushing which can make for very sloppy shifting. It's hard to get to but easy to press in. But it is may not be a problem on yours. I had trouble finding this part and ended up calling MB Classic who provided it without any trouble. You can have it if needed.. BTW, you will have to be persistent with Sun Valley. I put one of their ATs in and it took many emails for them to respond to my problem.

Re: [MBZ] 1982 240D Shifting
If it's like my 82 SD, there is a mechanical (cable or rod) linkage from the throttle that controls the shift points and a vacuum signal (from the injection pump) that controls shift firmness. The vacuum signal uses the vacuum pump, a restriction, and a variable leak (also controlled by throttle linkages) to simulate manifold vacuum of a gas engine. > -Original Message- > From: Mercedes [mailto:mercedes-boun...@okiebenz.com] On Behalf Of > Kevin Kraly via Mercedes > Sent: Thursday, September 19, 2019 7:34 PM > To: mercedes@okiebenz.com > Cc: Kevin Kraly > Subject: [MBZ] 1982 240D Shifting > > We took Hildegard out for a test drive today, and she seems to be running > better since the valve adjustment.

search sunvalley mercedes transmission. somewhere in the archives Marc should have the vacuum diagram and adjusting instructions for 82 240D.

Re: [MBZ] 1982 240D Shifting
Kevin, The valves on the top of the valve cover manage the EGR, I believe, so they wouldn’t affect shift points. There should be a VCV (vacuum control valve) on top of the injection pump that is the major player in the shift/vacuum function. Vacuum goes to the VCV and then to the vacuum modulator on the transmission. Here is my transmission vacuum adjustment procedure for W123 and W126 cars - I’m sure the 240D is similar.

[MBZ] 1982 240D Shifting
We took Hildegard out for a test drive today, and she seems to be running better since the valve adjustment. The shift points seem to occur at specific speed and engine RPM rather than throttle positions. All vac lines leading inside the car are disconnected and capped, but all of the lines atop the valve cover seem to be connected, but most likely not in their proper positions. I know that there’s a VCV on top of the IP that controls the transmission, but I’m not sure if it’s even working. I may have to take it into a shop since I can’t see a pressure gage for vacuum at the different ports. What should I check first?
