Automatic Transmissions Flashcards
At torque converter stall:
a. Two members are stationary and one is turning b. One member is stationary and two are turning c. None of the members are stationary d. All of the members are stationary
a. Two members are stationary and one is turning
A torque converter is made up of these elements. They are:
a. Torus, stator and impeller b. Stator, turbine and impeller c. Pump, impeller and stator d. Turbine, stator and torus
b. Stator, turbine and impeller
At the coupling point:
a. All members are rotating b. Two members are stationary and one is turning c. there is no vortex flow d. There is no rotary flow
a. All members are rotating
Torque multiplication is greater at what speed?
a. Low speed b. Cruising speed c. High speed d. On the float
a. Low speed
A torque converter one way clutch that will not hold will cause:
a. High fuel consumption at high speed b. Poor performance at high speed c. Poor torque multiplication at high speed d. Low engine rpm at converter stall
d. Low engine rpm at converter stall
A torque converter roller clutch that is locked in both directions will cause:
a. Low engine rpm at low speeds b. Poor torque multiplication at low speed c. Poor engine performance at high speed d. High fuel consumption at low speed
c. Poor engine performance at high speed
The purpose of the guide ring in a torque converter is to reduce the oil:
a. Movement between members b. Turbulence c. Level int he coupling phase d. Impact Angle
b. Turbulence
The maximum time allowed for performing a stall test is:
a. 10 seconds b. 5 seconds c. 15 seconds d. It does not matter
b. 5 seconds
When lock up torque converters lock, they connect the:
a. Impeller to the input shaft b. Impeller to the turbine c. Turbine to the converter cover d. Converter cover to the impeller
c. Turbine to the converter cover
Vortex flow is high when:
a. Engine at high stall speed b. Vehicle at coupling point c. Torque converter lock up d. Vehicle is in coast mode
a. Engine at high stall speed
The lock up converter is most likely to lock under this condition
a. Idle b. Heavy acceleration c. High gear and cruise d. Deceleration
c. High gear and cruise
The impeller is attached to:
a. The input shaft b. The output shaft c. The flex plate d. Stator
c. The flex plate??
answer says a. The input shaft, but I think that’s wrong
