Exam 41: Automatic Transmissions and Transaxles

Overrunning clutches are capable of ______.

Explain the functions of the torque converter.

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?

In a simple planetary gearset, whenever the planetary carrier is held, the condition will be ______.

Two technicians are discussing transmission oil pumps. Technician A says the oil pump is driven by the turbine shaft. Technician B say the pump is driven by the hub on the back of the converter housing. Who is correct?

Multiple disc clutches in an automatic transmission are engaged by spring tension and released [disengaged] by hydraulic pressure.

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 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?

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 driven or output member is always the ring gear. Who is correct?

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

All the following are components of the torque converter EXCEPT:

Which of the following is NOT a component of the TCC?

What is the function of bands in automatic transmissions?

What is the function of the governor in automatic transmissions?

What is a servo?

Automatic transmissions designed with constant-mesh helical gears on parallel shafts, similar to the design of a manual transaxle, are used in ____________________ automobiles.

The valve body assembly is comprised of the valve body, separator plate, and transfer plate.

Which of the following components is NOT part of a lockup torque converter?

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?

In a simple planetary gearset, when the planetary carrier is held the gearset produces a ______.
