Exam 41: Automatic Transmissions and Transaxles

The ____________________ member of a simple planetary gearset is sometimes called the reaction member.

What is the function of the valve body?

An automatic transmission or transaxle selects ____________________ according to engine speed, powertrain load, vehicle speed, and other operating factors.

Where are lip seals used in an automatic transmission?

The overrunning clutch inside the torque converter is attached to the ______.

If the sun gear and planetary carrier are both driven [locked together], the gear ratio will be ______.

Power transfer through a planetary gearset is only possible when two of the members are held at rest, or if two of the members are locked together.

A servo assembly converts mechanical force to hydraulic pressure.

Name five components of a multiple disc clutch assembly.

Which of the following torque converter components is attached to the engine flywheel?

_____type and roller overrunning clutches are used to hold or drive members of the planetary gearset in one direction and allow them to freewheel in the opposite direction.

Excessive pump pressure is controlled by the ____________________ valve.

The transmission cooler is normally located ______.

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?

Two technicians are discussing transmission bearings. Technician A says thrust washers are used to support radial loads. Technician B says thrust washers are used to support axial loads. 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?

What is the difference between torque converter rotary fluid flow and vortex fluid flow?

Technician A says a Simpson geartrain is an arrangement of two separate planetary gearsets with a common sun gear, two ring gears, and two planetary pinion carriers. Technician B says a Ravigneaux gearset has two sun gears, two sets of planet gears within a single carrier, and two ring gears. Who is correct?

In addition to the compound planetary gearsets, many automatic transmissions are fitted with an additional single planetary gearset to provide additional forward gear ratios.

Technician A says the turbine shaft is splined to the turbine and transfers power from the torque converter to the transmission's main driveshaft. Technician B says the transmission oil pump is driven by the turbine shaft. Who is correct?
