Operates hydraulically and mechanically

Lock-up

The oil flows to the __________ side of the TCC plate to apply the clutch.

apply

Technician A says that during the stall phase there is maximum torque multiplication. Technician B says that during coupling phase there is minimum difference between the turbine and the impeller speed. Which technician is correct?

both techs

The _________ assembly absorbs vibration to provide a smooth engagement.

damper

The one-way clutch in the stator freewheels at lower speed when the vehicle requires more torque.

f

The split rings increase torque multiplication.

f

The turbine rotates in the opposite direction of the impeller.

f

Vortex flow allows the fluid leaving the turbine to return to the impeller in the same direction.

f

The oil from the pump flows between the apply passage through the converter hub andthe __________ shaft.

stator

Centrifugal force causes the oil hitting the center of the impeller to flow towards the rim.

t

Fluid exiting the impeller rim hits the turbine, causing the turbine to rotate.

t

Stator redirects fluid flow from the turbine to the impeller, providing torque multiplication.

t

The housing and the impeller rotate at engine speed.

t

Technician A says that the lock-up torque converter eliminates slippage by locking the impeller and stator together. Technician B says that the lock-up torque converter improves fuel economy. Which technician is correct?

tech b
