A)A only
B)B only
C)both A and B
D)neither A nor B

Answer 3

C

Question 4

A)impeller
B)stator
C)turbine
D)output shaft

Question 5

When should the ATF level be checked on vehicles with a dipstick?

A)when the transmission is cool
B)when the transmission is overheated
C)when the transmission is at operating temperature
D)none of the answers are correct

Question 6

________ drive has a gear ratio of 1:1.

Question 7

The transmission cooler is often located ______.

A)in the engine radiator
B)above the transmission
C)in the back of the transmission
D)in the transmission pan

Question 8

Low gear ratios increase torque and accelerate quickly, while high gear ratios allow lower engine speed and economy but with low torque output.

B)throwout bearing
C)clutch disc
D)clutch cable

Question 16

A torque converter uses a pump to push fluid to drive the input shaft of the ______.

A)engine crankshaft
B)flywheel
C)pressure plate
D)transmission

Question 17

The ____________ ______________ switch or sensor is used to provide information to the computer about which gear or range the transmission is placed in by the driver.

Question 18

A manual transmission consists of all of the following EXCEPT a (an) ________.

A)input shaft
B)countershaft
