If the stall speed is slower than specified what could be the cause
A slipping stater clutch
Technician a says that at *Speed the impeller is spinning as fast as the engine can drive it. Technician B says that a stall speed the turbine is stationary
Both technicians
Technician a says that fluid motion inside a converter is controlled by the guide ring the technician B says that fluid motion inside converter is controlled by the stator vanes
Both technicians
Technician a says that the flexplate connects the torque converter to the crankshaft technician B says that the torque converter is considered part of the transmission
Both technicians
Technician a says that the turbine provides torque input to the transmission gear set through the input shaft technician B says at the pump impeller is a driving member and the turbine is the driven member
Both technicians
Creep is___
Caused by slippage inside the torque converter, normal operation, causes a vehicle to move slightly when the engine is an idle speed in the transmission is in drive gear
Can you lock up torque converter the
Clutch plate is splined onto the turbine shaft clutch line and transfers power through a mechanical connection during lock up
The torque converter clutch circuit is controlled by the
Command from the PCM/TCM
A torque converter is more efficient while
Cruising
During the Coupling stage the stater one-way clutch remains locked
False
Modified engine may need a torque converter that is
Loser, has a higher stall speed, smaller in diameter
A vehicle creeps faster than normal when the engine is called what is the most likely cause
Normal operation
The stater is mounted on a
One way clutch
The torque converter should be checked by a technician for all the following except
Proper balance
A torque converter turbine end play has measured to be .070 inches what action should the technician take
Replace or rebuild the torque converter
The fluid flow around the circumference of the converter is called
Rotary flow
Stall testing can be used to find
Slipping clutches slipping bands is slipping stater clutch
A stall test is used to check the
Stater
Technician a says that the torque converter impeller is attached to the flexplate and turns as the engine rotates. Technician B says that the turbine is attached to the flexplate and turns as the engine rotate
Technician a
Technician a says that the torque multiplication Phase can occur in the state one-way clutch begins to freewheel technician B says that the torque multiplication phase can occur when the state or one way Locks up
Technician be
Lock up torque converter's use a definite assembly to dampen
Tortional vibration
The parts of a torque converter are
Turbine, impeller, stater
The fluid flow from the impeller through the turbine in stater is called__flow
Vortex
During the coupling phase the
Vortex flow nearly stopped
