Exam 9: Torque Converter Principles

A torque converter center hub is mounted on a one-way clutch and is splined to the transmission stator support shaft.

If the automatic transmission's shift linkage is not adjusted properly, the transmission position indicator will not be set correctly, the customer will not know which gear the vehicle is in, and the backup or reverse lights may not work.

The average torque multiplication for a torque converter in a passenger car is:

Which of the following are replacement choices for clutch friction materials?

Inside a torque converter, the one-way clutch allows the stator to rotate only in one direction. Technician A says that it will turn in the same direction as the output shaft. Technician B says it turns in the same direction as the impeller. Who is correct?

Tech A states that lock up torque converters are either fully applied or fully released. Tech B states that many manufacturers will pulse the torque converter on to prevent harsh application. Who is correct?

You are testing the solenoids on an Allison transmission and find the resistance of the trim solenoids to be 12.3 ohms. Tech A states that the solenoids need to be replaced. Tech B states that the resistance should be higher than 12.3 ohms. Who is correct?
