What do these two transmissions have in common? Well if you take the torque tube flange and diff off the first picture they are the same transmission.

What are they in? Well the first one is an automatic transmission from a 928. The second transmission is out of a Mercedes (w126, w140, w123, w124, w210, w201, w202, c107, r107, and r129). Certian things changed over the years with this trans, but on fun thing is they are vacuum modulated.

This means engine vacuum is used to shift the transmission. This was done in the era between cable shifting and electronic shifting.

Oh wait I forgot the important part. I am bringing this up because the banjo bolt on the front of the early 928s’ intake where the tube for the rear transaxle’s vacuum attaches is fricking missing!!! I swear I had threaded it back into the hole after I needed to move the line for doing the intake, but no I guess I didn’t.... Fucking yay. If I dropped it in the engine bay, then it may be lost forever.

Is that enough for science?

As a real live scientist, I heartily approve.

!!! UNKNOWN CONTENT TYPE !!!

Wait...I thought the 722.6 shifted via electronic solenoids in the w210? Ohh shit your right, that trans (in your pic) was used up to 1997 in w210's...I learned something today

Ah, the joys of the VACUUM ALL THE THINGS era. You lose vacuum and suddenly you have no transmission, door locks, and in the case of our W123, the AC controls and the engine itself.

My 06 GTO has vacuum actuated AC....

...how? I'm guessing it's just GM being GM?

Yeah pretty much. The doors and stuff are all vacuum actuated in the US GTO, but the Holden Monaro is electronic... WTF!! Plus the dash looks better with the electric AC

Out of curiosity, if that back side glass (last pic) breaks, is it a fortune to replace?

Seems like such a curved and unique piece you’d get charged a fortune

Oh yeah I am sure that if there is still NOS out there, that would be ridiculous $$

Fun Fact: 1941 Chevrolets had vaccum assisted maual transmissions.
