The earlier 722.3 transmissions will work on '85 cars, but the '85 722.3 
transmission won't fit onto an earlier car/engine. I'm NOT sure about 
the 722.416 transmissions from '85 California certified 300D/TD/CD/SDs, 
but they do have a high stall speed torque converters and the earlier 
transmissions with a torque converter with much lower stall speed would 
make the car feel REALLY sluggish and slow at low speeds.

There are not a lot of '85 722.416 transmissions floating around.
