Technician A says a rotor pump has a center rotor that is driven by the torque
converter. Technician B says a vane pump has a center gear that drives an outer
gear. Who is correct?
Technician A
In a lock-up converter, the ___________ and ___________ are locked together,
when conditions are suitable.
impeller and turbine
Which of the following is an additive found in typical transmission fluid?
All of the answers listed
Typically, when turbine speed reaches around 90% of impeller speed, torque
multiplication is about:
1:1
Technician A says antifoam additives help to prevent foaming of the transmission
fluid. Technician B says viscosity modifiers cause the transmission fluid to be
thick when cold and thin when hot. Who is correct?
Technician A
Technician A says modern automatic transmission cases are made of lightweight
aluminum and alloys. Technician B says on the rear or output side of the
transmission, there is an aluminum housing called the extension housing. Who is
correct?
Both Technician A and B
Technician A says there are many types of internal seals for an automatic
transmission. Technician B says a square-cut seal is usually made from cork.
Who is correct?
Technician A
Two technicians are discussing torque converters. Technician A says that a
torque converter does a similar job as the manual clutch. Technician B says that
the torque converter multiplies torque from the engine to the input shaft of the
transmission. Who is correct?
