I have a 78 240d. It has been sitting for 2 years. Now it won't shift into drive, and when it does on ocassion, it slips.(as if in neutral). Am i missing an adjustment? Is it time for a rebuild? Got any tricks?

It could just need a good cleaning. My Haynes shop manual (not a professional-grade manual) shows how to remove and clean out the valve body. I think that if this were not a common procedure, and relatively easy, they wouldn't include it. I haven't done this on a benz, but I have on other makes. You need plenty of time, so you're not rushed, and a large, clean work area.

Tranny Service is in need, alos the tranny is vacuum operated, and there is a an adjustment on the tranny. A small pin on the module is used for the adjstment (do not adjust more than a 1/4 at a time) traany service should be done first and check the vacum on the tranny,<br> <br> Clint<br> Mercedesautoparts.com

    Ok so I got a bit impatient. I have been looking for a diesel Mercedes for a while now. So long in fact I bought a 560 SEC to try and cure the want. The SEC is a great car but I still wanted an old W123 or W126 diesel. I found one locally and jumped on it as being a local car eliminated a...

    W123 E,CE,D,CD,TD,TE Class
    How did I come to be the owner of this 1985 300CD? Having owned a W201, 2 W124s and a W126 300SD I had read and heard so much about the W123 cars that I knew this would be the next Benz for me. I knew right from the start that it would have to be the coupe body style. I wanted something a bit...

  5. What did you do to your W123 in 2020?

    W123 E,CE,D,CD,TD,TE Class
    Happy New Year! May getting rich be as easy as getting fat! Today I started the finishing touches on my new speaker board. I hope to be done and dusted by Sunday, but I'm just as happy to interrupt the finishing and reinstall it incomplete if it means having music on my first week back to work.

    Greetings all, I am new to the 123 world and have been going through the engine to get acquainted with it. Engine has 153K on it. I have adjusted the valves, let the injectors soak in diesel purge, and did a diesel purge this morning. Before I did all of this, it would fire up in the...
