Looks like I'm screwed. I guess I better start shopping for a used transmission.

$99.99 Pick-n-Pull
post a ad here looking for one

BTW You can tow a Mercedes a short distance with the rear wheels on the ground at low speeds as already mentioned : What you must do to avoid damage also is leave the motor running at idle in neutral.
this keeps the tranny lucubrated ( front pump ) .
Now most cars that you tow don't run hummm so that would be out .

Some days I should have just stayed in bed. I drove 50 miles to work on the car and realized I grabbed the wrong keys. At least I was able to change the thermostat because I had left the car unlocked on Wednesday.

Pulled the transmission pan today and it was full of chunks of metal and metal shavings. The search is on for a replacement transmission.

You Might Buy a parts car or a engine and transmission . Sometimes you get a better deal that way . But you should be able to find just a tranny for not much at all
Note Be Sure You replace the front Pump seal and you may as well replace the rear one also . Once you pull a used tranny the front seal most often gets cracked .

Thanks for the advice. That is a good plan. I've been told to change the torque converter also. I'be found a suitable candidate, with Fonzi's help. Now I just have to get the deal done.

As requested by Dan, I'm uploading a picture he took of the transmission he just purchased:

Thanks Fonzi. It's been a long day, 550 miles or so of driving, but the old transmission is out and the replacement will be installed Friday. Hope to be driving the car by Friday or Saturday.
We did notice that the speedometer cables are different on the two units, but everything else seems to be the same.

Seeking a little help and clarification for dgosh28.

New transmission number 114 270 1401 004370 which was supposedly (and apparently) from a 1972 250 114.011.12.xxxxxx (last six digits in question).

The transmission in dgosh28's 114.011.12.0030xx car appears like it was probably a 114 270 1201 (not a 1401) as it appears that both the 114.011 (m130 sedan) and 114.023 (m130 coupe) had the trans change at some point from the 1201 to the 1401. The funny thing is that the EPC says chassis number ~7030 for the sedan (well above dgosh28's, which is why I assume his old one wS a 1201), and Transmission Number ~5000 for the coupe. This is strange as my old sedan 114.011.12.002569 apparently had trans ~5200 or something. ???? Strange.

Anyway, both the 114 270 1201 and 114 270 1401 transmissions seem to have only been used in the m130 w114 cars: 114.023 and 114.011, and those are the only two automatic transmissions that went into those two model. So... I told Dgosh28 that that transmission MUST fit, even if it isn't the correct part number. So he went and bought it.

Last night I got a message saying that the speedo cables appear to be different, one supposedly being like a string. String? Huh? Might that be the column gear selector string or something? Weird.

Anyway, today I checked the early and late sedans 114.023 and both seem to use the same speedometer cable. So... I'm still feeling confident that he got the right transmission, but looking to see if anyone happens to know a little but more about the potential differences in the 114 270 1201 and 114 270 1401 transmissions. When I look at automobile-catalog.com for specs, I cans see any difference in gear ratios or anything. (I know, maybe not the best source.)

Anyway, all info on the differences seems to be minimal, other than dgosh28's statement that the instrument/control connections appear like they could be different on the two.
