Iam putting a 72 232 in my 64 american and have decided to use
transmission
from 72 or later. My repair manual says that the 727, 904 & 998 were
Automatics 
that will work with the 232 six. Which would be the best for my 64. I
realize
that I will need to change the yoke on the drive shaft and other stuff.
Are
these trans fluid or air cooled

The 904 is OEM for all of the AMC I-6 engines used from 1972 on with a
couple of fleet or heavy duty exceptions. 
Any year 904 will work and bolt up to the engine. The 904 transmission
is reliable; parts are commonly available and although they can be
rebuilt with heavy duty parts to improve the reliability it is generally
not needed. In 1980 AMC started to use the lock up torque converter
version which is interesting as first and second gear are lower geared
to improve acceleration when using taller rear axle gears. For example
2.53 is standard on a 1980 Spirit. When used with that rear axle ratio
you can expect better gasoline mileage and as the transmission is set up
with lower gears in 1st and 2nd acceleration is not compromised. Also
you can play with the lock up point of the torque converter to get the
transmission to act as a poor mans 4 speed automatic. But if that does
not float your boat any, they all work. 
It could be neat though to locate one that has a floor shift package set
up with it so you do not have to figure out how to get the column shift
to work and they were available but probably more commonly found in the
Spirits than any other model. 
They are all liquid cooled with lines running to the radiator. If you
find a parts car purchase the transmission, torque converter,
transmission mount, yoke, cooling lines, kick down linkage from the
carburetor to the transmission and shift linkage to ease your
conversion. They can be found in any AMC I-6 automatic equipped
automobile.
