The transmission in the pictures you took is a 722.1 transmission. It was put in Mercedes vehicles up to about 1984 after that the 722.3s and 722.4s took over propper...

There is a big difference between the 722.1 and the 722.3/4 transmissions.

You can see lots of differences by looking through these PDFs

I don't think you'll learn all that much for your problem by taking a 722.1 to bits but - hey - have fun!
