Torque Converter: Description and Operation
Turbo Hydra-Matic 3L80 & 3L80HD (400 & 475)
Stator, Alternator
The convertor also has a smaller vaned section, called a stator, that funnels the oil back to the converter pump through smaller openings, at increased
speed. The speeded up oil directs additional force to the engine driven converter pump, thereby multiplying engine torque. Without the stator, the torque
converter would only provide a fluid coupling.
Torque Converter
The torque converter is of welded construction and is serviced as an assembly. The unit is made up of two vaned sections, or halves, that face each
other in an oil filled housing. The pump half of the converter is connected to the engine and the turbine half is connected to the transmission.
When the engine makes the converter pump revolve, it sends oil against the turbine, making it revolve also. The oil then returns in a circular flow back
to the converter pump, continuing this flow as long as the engine is running.
