A slight correction--"straight" fluid drives (which were used on older Dodges 1941-1948) did not have the semi-automatic function (M-6). Although Chrysler specifications indicated Fluid Drive was standard, I have never know of any after 1941 that did not have the semi-automatic function, either M-3 (vacuum) or M-5 (hydraulic w/o torque converter) or M-6 (with torque converter.)
