How does a torque convertor transmission work in automobiles? There is a combustion in the engine, a crankshaft, that converts it into a rotary moment, so where does this rotary moment go and how are the shifts changing? Obviously, ATF running somewhere, along where? Doing what?
In: Engineering
The crank shaft is connected to a turbine in the torque converter, which is a donut-shaped metal case filled with ATF. The drive shaft is connected to a second turbine in the torque converter, but the two aren’t physically connected. At low RPM the engine output just spins freely in the fluid, but at higher RPM the drive shaft turbine gets driven by the spinning of the transmission fluid.
