Question 1

The transmission cooler is normally located ______.

Accepted Answer

The transmission cooler is typically located within the radiator, as it circulates transmission fluid through the radiator to dissipate heat before returning back to the transmission.

Question 2

Single wrap and double wrap are types of ______.

Accepted Answer

Single wrap and double wrap are types of bands in automatic transmission.

Question 3

The function of the throttle valve in the valve body is to ______.

Accepted Answer

The throttle valve in the valve body is designed to produce a fluid pressure that is proportional to engine load, which helps in adjusting the transmission's shift points based on the engine's power demands.

Question 4

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?

Accepted Answer

Technician A is correct because a Simpson geartrain indeed consists of two separate planetary gearsets with a common sun gear, two ring gears, and two planetary pinion carriers. Technician B's description inaccurately describes a Ravigneaux gearset, which actually has two sun gears, a set of long and short planet gears within a single carrier, and one ring gear, not two.

Question 5

Which of the following torque converter components connects to the transmission input shaft?

Accepted Answer

The turbine is the component in a torque converter that connects to the transmission input shaft, transferring power from the engine to the transmission.

Question 6

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?

Accepted Answer

Thrust washers are used to support axial loads, so Technician B is correct. Technician A is incorrect because thrust washers are not used to support radial loads, but rather to prevent axial movement.

Question 7

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?

Accepted Answer

Multiple-disc clutch packs are used to hold or drive gearset members while overrunning clutches are unique in that they only allow rotation in one direction and are used to prevent the transmission from locking up when coasting or decelerating. Therefore, technician A is correct, but technician B is incorrect.

Question 8

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?

Accepted Answer

Band lining material can be made from a variety of compounds, including semimetallic compounds and paper-based materials. Both technicians are correct in this context.

Question 9

All the following are components of the torque converter EXCEPT:

Accepted Answer

The answer of All the following are components of the...

Question 10

Which of the following pressures increases as road speed increases?

Accepted Answer

Governor pressure increases as road speed increases. Line pressure, throttle pressure, and converter pressure can all change for various reasons, but they are not directly correlated with road speed.

Question 11

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

Accepted Answer

The TCC, or Torque Converter Clutch, does not include a roller clutch among its components. The TCC typically consists of a damper assembly, piston plate, and clutch friction plate, which work together to lock the engine and transmission input shaft together at high speeds to improve fuel efficiency and performance. The roller clutch is a separate component used in other parts of the transmission system for different functions.

Question 12

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?

Accepted Answer

Neither technician A nor technician B is correct. Thrust washers are devices that control axial loads, while bushings are devices that control radial loads.

Question 13

When hydraulic pressure is applied to one side of a _____ servo, the band is applied. When hydraulic pressure is applied to the opposite side of the piston the band is released.

Accepted Answer

The answer of When hydraulic pressure is applied to one...

Question 14

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?

Accepted Answer

Technician A is partially correct - the lockup piston clutch does improve fuel economy by reducing slippage between the engine and transmission. Technician B is also correct - the damper assembly is designed to both transmit driving torque and absorb shock. Therefore, both technicians are correct.

Question 15

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

Accepted Answer

The impeller is attached to the engine flywheel.

Question 16

The multiplier of torque converter fluid power is the ______.

Accepted Answer

The stator in a torque converter redirects fluid returning from the turbine to the impeller, increasing the fluid velocity and thus multiplying the torque.

Question 17

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?

Accepted Answer

Technician B is correct. The oil pump is driven by the hub on the back of the converter housing, not the turbine shaft.

Question 18

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?

Accepted Answer

Technician A is correct in stating that spool valves have at least two lands that are connected by a thin stem. Technician B is also correct in stating that check ball and poppet are valve designs. Therefore, both technicians are correct.

Question 19

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

Accepted Answer

The answer of Butt-end, open-end, and hook-end are types of...

Question 20

A Belleville spring is commonly found inside a _____.

Accepted Answer

The answer of A Belleville spring is commonly found inside...
