W123 transmission swap Q

Hi all. Is it possible to pull a (manual) transmission without removing the engine? Last two engine swaps I've taken out the engine and tranny as a unit.
Not sure if it's possibly to only take out the transmission. Anyone?

Yes, it is quite easy. Just depends on whether you prefer working longer on your back or on your feet.

Yes. I've done it, but I had a lift and a tranny jack at my disposal at the time. I've R&R'ed a an automatic before without benefit of those, and it takes a lot more time and effort, but it can be done.

The transmissions used in the 240D from 81 - 83 is the all one piece Aluminum Case, and weigh around 54 pounds.

The older one with the Iron Case and Aluminum Bell Housing is a bit heavier.

It`s just a matter of disconnecting the Driveline, Exhaust Hanger, Shift Rods, Clutch Line, Transmission Mount, and then the 2 Starter bots and the other 6 or so trans to eng bolts. then laying on your back grab the trans and lift and wiggle it back to clear the Input Shaft and it is yours.

Might need to use a Jack to hold the back on the engine from sagging and take the stress off the Engine mounts.

Removing the manual transmission is easy.
