Exam 41: Automatic Transmissions and Transaxles

Which of the following pressures increases as road speed increases?

Technician A says a simple planetary gearset can provide two reverse gear ratios. Technician B says a simple planetary gearset can provide two forward reduction ratios. Who is correct?

At coupling speed, the overrunning clutch in the torque converter is ______.

Technician A says the transmission oil pump is driven by the converter shell and continually delivers transmission fluid under pressure into the torque converter through a hollow shaft at the center axis of the converter assembly. Technician B says transmission fluid leaving the turbine is directed out of the torque converter to an external oil cooler and then to the transmission's oil sump or pan. Who is correct?

A transmission band assembly is used to drive a planetary member.

A Belleville-type clutch piston return spring can be used to multiply the force applied to the clutch.

Technician A says vortex flow is the flow of transmission fluid from the center to the outside edge and back. Technician B says rotary flow is the oil flow around the circumference of the torque converter. Who is correct?

Technician A says a purpose of a lockup piston clutch is to improve fuel economy. Technician B says a lockup piston clutch is designed with a damper assembly to transmit driving torque and absorb shock. Who is correct?

Hydraulic valve designs are being discussed. Technician A says spool valves have at least two lands that are connected by a thin stem. Technician B says check ball and poppet are valve designs. Who is correct?

_____ bearings are thrust washers fitted with roller bearings used to reduce endplay.

Today's transmissions have at least one ____________________ gear to reduce fuel consumption, lower emission levels, and reduce noise while the vehicle is cruising.

Overrunning (one-way)clutches can be either roller-type or ____________________type clutches.

Identify the three basic components in a simple planetary gearset.

What is the function of bands in automatic transmissions?

In a planetary gearset, the ring gear is sometimes called the ____________________ gear.

Technician A says devices that control radial loads are called thrust washers. Technician B says devices that control axial loads are called bushings. Who is correct?

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

________________ control the axial movement of rotating transmission components.

Technician A says torque converters are three-piece units that are bolted together and can be easily disassembled for cleaning and repairs. Technician B says the torque converter is completely filled with pressurized transmission fluid. Who is correct?

Transmission gaskets are made of rubber, cork, paper, or ____________________.
