Exam 41: Automatic Transmissions and Transaxles

All automatic transaxles use a simple planetary gearset.

Which torque converter components is attached to the engine flywheel?

Butt-end, open-end, and hook-end are types of ______.

The function of automatic transmission fluid is to ______.

What is the function of an accumulator in an automatic transmission?

On many hybrid vehicles the transmission uses _____ to drive and hold planetary gearset elements.

Overrunning clutches can ______.

Automatic transmissions use a fluid clutch known as a ____________________ to transfer engine torque from the engine to the transmission.

A lockup torque converter eliminates the ____________________ percent slip that takes place between the impeller and turbine during the fluid coupling stage.

Simple planetary gearsets are being discussed. Technician A says any one of the three members can be used as the driving or input member. Technician B says the ring gear is always the driving or output member. Who is correct?

Two technicians are discussing band lining material. Technician A says the band lining material is a semimetallic compound. Technician B says the band lining material is paper based. Who is correct?

In addition to conventional snap rings, some are wave shaped and some are available in different thicknesses to adjust multiple-disc clutch pack clearance.

Technician A says multiple-disc clutch packs are capable of holding or driving gearset members. Technician B says overrunning (one-way)clutches are capable only of holding gearset members. Who is correct?

Technician A says if the sun and the ring gear are both driven [locked] and the carrier is the output, the condition is direct drive. Technician B says if the carrier and the sun are both driven and the ring gear is the output, the condition is direct drive. Who is correct?

Technician A says the names of the components inside an automatic transmission are based on their function; namely what gear are they used to control. Technician B says the names of the clutches, bands, and servos are based on their location in the transmission. Who is correct?

When a sun gear is the input member and the planetary carrier is held, the ring (internal/annulus)gear will be driven at a forward overdrive speed.

Lepellietier gearsets rely on a combination of ________________ and _________________ gearsets.

A ____________________assembly converts hydraulic pressure into a mechanical force that applies a band to hold a drum stationary.

Whenever two members of a simple planetary gearset are locked together, the output will be direct drive.

A CVT transmission uses _____ to provide speed reduction and torque multiplication.
