What's the difference between these standard transmission?
Different casting numbers.
Referring to the photos in post #6
All 3 of these are the 1951-54 overdrive version and it is hard to tell 3 from 8 in the casting numbers.
The upper individual photo casting number is 412234 which is the case for 22nd and 23rd Series models with overdrive but is missing the 4 tapped holes in the cast bosses on the side for the rear motor mounts on these cars. With a casting date of 10.9 it may have been left over from 1950, never drilled and then used in a 1951 model.
The correct casting number in the lower 2 photos is 433192 which is the main case for all 1951-54 models, both standard and overdrive.
Not sure why the u-joint flanges are different.
The numbers quoted are as shown in the 1948-54 parts list.
