Cheers all,

1982' W123 D

Well it has happened to me. Driving around and all of the sudden, it
will not shift into DRIVE, so I'm stuck in L or H or whatever 2nd is
I had to stop and put it into park, and now it seems to do it all the
time. When I was on the freeway today, I was in D and I pressed on the
throttle, and the engine revved up, but didn't go faster, it was kinda
scary. Is this a preview of upcoming attractions, like total
transmission failure? Anyways

My friendly neighbor says he had the same problem, and he drove right to
the shop, they spend $40 and he was out of there in 20 minutes.

As you may know I am not an expert, can someone explain what I need to
do, and what exactly part I need? From sniffing around the old
newsgroups, do I need a "123 Turbo Diesel Transmission Vacuum Shift Valve" ?

It sounds like that's what I need. If someone can give me some good
advice, I will do it and add it as one of my guides, as always.

oh yeah, so the shifter is physical always in D, but sometimes the car
will only upshift to the middle gear (2nd/S?) L-S-D it's definatly in
the second aka middle gear. If I shift into N and then back into D,
then it will uusually go from 2 to D in about 1 second. The rest of my
vacuum is pretty good. Plugged all the leaking locks, replaced ignition
shutoff valve and injection shutoff valve. shuts off quick.

I have noticed recently that the time from Park - Reverse does take a
second longer than usual.

From a standstill it shifts from Park to first fine

P-1, 1-2, 2-3 just like normal. 3-4 is where my problems lie.

It IS freezing here in Utah, but when it warms up (45 degrees F - 7 C)
it seems to have no affect.

About a year ago I did replace the filter and fluid. Maybe I should st
least start there and do that -eh?

I scuttled and sold my 240D when it did this. Except I was stuck in
reverse!

then it just likes to stay at three. but then again, this morning it
was hesitant, but it did go right into drive at the appropriate time.


warmed up, it will slip more so. This morning it was fine. The only two
other times it was really bad, was when the car had warmed up to normal
operating temperature.

I will definatley get myself some synthetic Amsoil ATF.

I see online everywhere "AT Rebuild kits" for my car's tranny. (W4A 040
Overhaul kit, 722.3)

Does anyone have any experience with this? I an just some nerd, but I am
willing to learn. Of course, I'd like to "try" all the cheap and easy
stuff first. Transmission Vacuum Valve? But I will do what I have to
do. I think it's actually been "slipping" for years, it would be nice to
get a nice new tranny.
