Re: 1950 standard transmission fluid questions

The transmissions are three speed with second and third synchronized. Overdrive was an option so your car may not have that unit attached to the rear of the transmission. In that case just check the oil in the trans section and ignore the instructions on checking or filling the OD unit.
If the car has been sitting a long time there is a good possibility the two levers at the bottom of the steering column are the issue. Those often did not get much benefit of a regular oiling and frequently the top one is rusted and even seized to the shift tube. They need to both be free to turn individually on the tube or the detent in the transmission will see the movement of both and not permit either to move since that could select two gears at once. The selector tongue operated by pulling the lever normally rests in the top 2-3 lever. Pulling the inside lever to the R and 1 spots moves the tongue to select the bottom lever to rotate with the tube while the top 2-3 lever remains stationary. Leaving the inside lever in its regular resting spot lets the tongue rotate the top 2-3 lever and the bottom R-1 lever stays stationary as the tube rotates.
There is a small oil hole more or less on the engine side of the tube which should periodically get a few drops of oil. The oil will flow down inside the tube and run out to catch the selector tongue on its splines and also a bit runs out to the lower lever but the top lever never gets any oil unless the oil can misses the hole and some oil spills and runs down the tube.
I would suggest some oil in the small hole and also a few drops at the top of the upper lever so it can run down between the lever and tube. It may even take some penetrating oil for the top lever. If the lever has already seized it may require disassembly to free it. Above all do not force anything or you run the risk of breaking the pot metal assy behind the steering wheel where the inside lever attaches.
