Question 5

Technician A says some vehicles have the transmission remotely mounted from the differential. Technician B says the transaxle includes the transmission and final drive. Who is correct?
A) A only
B) B only
C) both A and B
D) neither A nor B

Accepted Answer

Technician A is correct; some vehicles have a remotely mounted transmission from the differential, which means the two components are not connected. 
Technician B is also correct; a transaxle includes both the transmission and final drive in one unit, commonly found in front-wheel-drive vehicles.

Question 9

What pin moves out of its notch and prevents the other shift rails from moving so that the transmission cannot be in two gears at once?
A) clutch
B) interlock
C) detent
D) zeroshift

Accepted Answer

The interlock pin is designed to move out of its notch and prevent other shift rails from moving, ensuring that the transmission cannot engage in two gears simultaneously. This mechanism is crucial for the proper functioning of a manual transmission, preventing gear clash and potential damage.

Question 13

The _____ assembly precisely locates the rail and shift fork and provides feel to the driver that a shift has been made.
A) clutch
B) interlock
C) detent
D) zeroshift

Accepted Answer

The detent assembly is responsible for precisely locating the rail and shift fork and providing a distinct feel to the driver that a shift has been made. The clutch is responsible for engaging and disengaging the transmission from the engine, while the interlock prevents the driver from shifting into the wrong gear. Zeroshift is not a relevant term in regards to transmission components.

Question 14

What is the difference between a transmission and a transaxle?

Accepted Answer

The answer of What is the difference between a transmission...

Question 15

_____ in a transmission that must be meshed to obtain reverse gear; it is used only in reverse, and does not transmit power when the transmission is in any other position?
A) Counter gear
B) Reverse idler gear
C) Reverse drive gear
D) First gear

Accepted Answer

The reverse idler gear is the gear in a transmission that must be meshed to obtain reverse gear. It is only used in reverse and does not transmit power in any other position. The other choices do not accurately describe this specific gear.

Question 16

What is the purpose of overdrive in the gear assembly?

Accepted Answer

The answer of What is the purpose of overdrive in...

Question 17

A _____ transmission is found in vehicles which have a transaxle mounted directly to the rear differential and use a shift shaft located at the front of the transmission.
A) remote
B) zeroshift
C) self-shifting
D) automatic

Accepted Answer

A remote transmission would have the shifter located further away from the transmission or transaxle, while a zeroshift transmission does not require a clutch to shift and a self-shifting transmission is simply another term for an automatic transmission. Therefore, the best choice is A, as it accurately describes the location of the shift shaft in relation to the transmission.
