Now that I have two cars (both 300SD) and a spare engine and transmission, I decided to look on the ID plates to find their numbers. The ID plate for the engine is on the right-hand side, facing the engine, just behind the oil filter housing. It is very difficult to get to, and most difficult to clean. The numbers are stamped on a metal plate that extends down from the side.
The good news is that the number of transmission-specific VIN patterns is on the. Chevrolet; Chrysler; GMC; Lamborghini; Lexus; Maserati; Mercedes-Benz. Vehicle Transmission Vacuum Serial. The serial number can be a critical piece of information if you need to. The next step is to understand how Mercedes.
I used a q-tip soaked in rubbing alcohol to wipe off the grease, along with an extended screwdriver to scrape the grease off, and a shirt attached to the screwdriver to wipe it down some more. Use a very bright, focused flashlight to read the numbers, even in broad daylight. The engine ID plate has 14 numbers. The first three numbers indicate the type of engine. The second three numbers indicate the version.
The next two numbers indicate driver's side and transmission type. The last six numbers are the serial number. I have the following engines: Daily driver' engine: 617 950 12 008 801 Type: 617 Version: 950 Driver's Side: 1, which is Left-Hand side Transmission: 2, which is automatic Serial Number: 008 801, which is the 8,801st engine of this lot. Seized engine: 617 952 12 098 496 Same as above, but version 952 (which was used in the W123s), and is the 98,496th engine made in this lot. Spare engine in garage: 617 950 12 005 997 Version 950 again (which was used in the 300SD), and is the 5,997th engine made in this lot. Does anybody know where the engines were manufactured, the city?
- The transmission ID number is 24 digits long. The location of the transmission identification number is on the passenger side of the transmission oil pan, (right behind the exhaust pipe if you are crawling underneath and want to see it). I was only able to find ID numbers on two transmissions. The car with the seized engine I could not see, because I did not raise it. Daily driver's transmission: 116 270 20 01 722 120 02 009 034 As far as I can tell, this is the original stock 300SD transmission.
The first 10 numbers designate the chassis/car?? The next 14 numbers designate the transmission itself.
This is a 722.120 (W 4 B 025) transmission. Dlportio driver package installer. What those numbers and letters mean, I don't know either. I suspect the last six digits are the serial number. Seized engine transmission: Unknown at this time. Spare transmission in garage: 123 270 78 01 722 315 02 596 833 Application: euro 1982-1984 300D / CD / TD (Turbo) (according to ). I have the Service Manual for the 617.95 engine, published in 1982. This seems to be part of a set, including Volumes 1 and 2 of 'Chassis and Body, Series 116, Starting 1973.'
The contents therein list the transmission manual as 'Service Manual 4-Speed, Automatic Transmission (W 4 B 025),' for the model 280S, 280SE. I am lacking the transmission manual. It seems to be very difficult to get hold of.

Daughters new car. What car/tranny do you have now? I can tell you that the 722.1 and 722.2 cases are the same(4-bolt pan, separate bellhousing), but the internals may be different.
Case in point I have an 80 300SD (722.120) that needs a tranny. I am going to attempt to swap a 722.112 out of a 77 280SE.
These are both 4 speeds, have a vacuum modulator and a mechanical rod from the throttle. I was about to snatch a 722.1xx from an 80 300D, but I finally noticed that it didn't have the rod. From what I can tell on mine, the 722.112 and 722.120 are both 4 speeds, and have the same physical characteristics.
I checked with Jaggi, a transmission rebuilder, and they think this swap will work. There may still be some subtle differences, though, such as in the valve bodies, but I was told it should work well enough. Your situation may be different. I wish there was more 'swap' data out there, but I haven't found much. Hmmm- how did we let one of those escape across the pond? I have a 300D turbo (sedan) that has a 722.315. I should think that would work in yours- but I'm not sure what all your options are in UK.
I would think a (1)4 speed that (2) starts in 1st gear (3)with a Bowden cable (4) a modulator and a (5) 6-bolt sump SHOULD work. There may be some gassers that would work. This Polish website, if you manupulate it, has some very good transmission data. I was able to glean some general data about my swap problem from there.
