The following paragraphs describe the major components of the X1100-
3B transmissions and their operational characteristics.
a. Torque Converter (fig. 1-8).
The torque converter has three
It acts as a disconnect clutch at idle (low flow - low
It multiplies torque, at low turbine and high pump speed,
to give greater starting or driving effect, when needed.
It acts as a fluid coupling smoothly transmitting engine
torque to the transmission gearing.
The torque converter consists of three vaned, cast aluminum elements:
pump assembly, stator, and turbine. The engine driven pump assembly
serves as the input element of the torque converter.
splined to the turbine shaft, serves as the output element, and the
stator serves as the reaction (torque multiplying) element.
A freewheel roller race, splined to the stationary ground sleeve
assembly, supports the stator.
The stator arrangement provides an
over-running clutch allowing the stator to rotate freely, in the
direction of engine rotation only.
Oil continuously flows through the torque converter assembly for
cooling and lubrication.
When the engine drives the converter, the
pump throws oil against the turbine vanes, and the impact of the oil
on the vanes causes the turbine to rotate.
