I thought that transmission by oil was called "hydrostatic" transmission. Where the engine drives a pump and the pressurised oil drives a hydraulic motor. Like on some combined harvesters and earthmoving vehicles.
Surely diesel hydraulic was like an engine driven automatic gearbox with torque converters (more than one) and cardan shafts (propshafts !) driving the wheelsets through a reduction gearbox.
Have we an "expert" to confirm this ??????
