ASE T3 Exam Practice Questions and Answers
1. The driver of a truck says he hears a grinding noise
when the transmission is in neutral and the truck is
stopped; but the noise goes away when the clutch
pedal is depressed. Which of these could be the
cause?
A. worn pilot bearing
B. worn input ...
D. Engine rating is such that the transmission requires the use of an oil cooler. - Ans:✔✔-5. The correct
answer is B. A rigid clutch cannot dampen the severe vibrations produced by modern high torque
diesels. The only other source of the kind of vibration torque that would cause such damage would be
misaligned driveshafts, and they have been found to be OK.
6. A truck fleet presently uses transmissions with an overdrive top gear ratio. It wishes to convert its
trucks to the use of direct-drive transmissions. In order to get approximately the same number of engine
revolutions per mile in top gear, the company would have to:
A convert the gearing in its rear axles to a higher (numerical) ratio
B. convert the gearing in its rear axles to a lower (numerical) ratio
C. it need not convert (the same rear axle ratio will produce the same engine revolutions per mile)
D. convert to lower-profile tires (which would turn more revolutions per mile) - Ans:✔✔-6. The correct
answer is B. On vehicles with overdrive. the engine turns more slowly than the transmission out put
shaft and the driveshafts at any given speed. With a direct drive transmission, the engine must turn at
the same speed as the driveshafts-in other words, with the same axle, faster. A numerically lower axle,
requiring fewer revolutions of the driveshafts, would be the only means of bringing the required rpm of
engine and drive shafts back down.
