Exam 7: Transmission Components

Tech A states that vehicles will have a parking pawl mechanism on the input shaft of the transmission. Tech B states that some vehicles will have a computer-controlled parking pawl. Who is correct?

Which of the following provides a way to measure engine load?

Technician A says a rotor pump has a center rotor that is driven by the torque converter. Technician B says a vane pump may be either a positive or variable displacement pump. Who is correct?

The spring mechanism that is built into the parking pawl assembly allows the driver to place the vehicle shift selector into park even when the parking pawl does not quite align with the notches in the drum.

Tech A states that some vehicles will include a transmission fluid warmer to help prevent wear in the transmission. Tech B states that all transmissions will have a transmission fluid cooler. Who is correct?

The front pump bushing is a friction-type bearing.

Multiple valves, solenoids, and sensors can be found in the valve body.

Technician A says that neoprene-type seals can typically be used on a servo piston. Technician B says a Teflon seal can typically be used on a servo piston. Who is correct?

Technician A says multi-disc clutches and bands are electrically controlled. Technician B says transmission failure can often be traced back to failed lip seals that have been leaking and preventing the piston from applying the full pressure needed to lock up the multi-disc clutch. Who is correct?

What design of brake bands are used in an automatic transmission?

Looking at the transmission fluid temperature (TFT) sensor value on the scan tool, which of the following values should the TOT match after the vehicle has been left overnight?

Which of the following are not used to release a multi-disc clutch?

What determines the torque capacity of a multi-disc clutch?

The __________ is the component that will deliver the torque from the transmission to either the driveshaft or the axle shafts.

Bands always come in a multiwrap configuration, which uses a band made up of three parallel straps that give increased gripping power as well as allow fluid to be squeezed out of the slots for quicker band application.

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?

In a variable displacement vane pump, what part below changes pump output based on the oil pressure acting on it?

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?

The torque converter can multiply torque from the engine to the input shaft of the transmission when required by driving conditions.

Technician A says that a torque converter is located between the engine and the transmission. Technician B says that a torque converter performs a similar function as a clutch in a manual transmission. Who is correct?
