Fill in the Missing Words

  1. Place the missing word to complete the following statement about transmission gearsets using the following words.

Missing Words: axle, calculated, final, first, fourth, gears, increased, large, meshes, multiplying, ratio, second, shaft, torque, transmission

Power is moved through the ______________ via four gears (two sets of two gears). Speed and torque are altered in steps. To explain how this works, let us assign numbers to each of the _______________. The small gear on the input shaft has twenty teeth. The gear it _____________ with has forty. This provides a gear ratio of 2:1. The output of this gearset moves along the _____________ of the forty-tooth gear and rotates other gears. The gear involved with ______________ gear has fifteen teeth. This gear rotates with the same speed and with the same _____________ as the forty-tooth gear. However, the fifteen-tooth gear is meshed with a _____________ gear with thirty-five teeth. The gear ______________ of the fifteen-tooth and the thirty-five-tooth gearset is 2.33:1. However, the ratio of the entire gearset (both sets of two gears) is 4.67:1.

The driveline’s gear ratios are further _____________ by the gear ratio of the ring and pinion gears in the drive axle assembly. Typical _____________ ratios are between 2.5 and 4.5:1. The final (overall) drive gear ratio is calculated by _____________ the transmission gear ratio by the final drive ratio. If a transmission is in first gear with a ratio of 3.63:1 and has a ______________ drive ratio of 3.52:1, the overall gear ratio is 12.78:1. If _____________ gear has a ratio of 1:1, using the same final drive ratio, the overall gear ratio is 3.52:1. The overall gear ratio is ______________ by multiplying the ratio of the first set of gears by the ratio of the _______________ (3.63 times 3.52 equals 12.78).

AURLTX101 Diagnosing and repair light vehicle manual transmissions

Multiple choice. Circle all the correct answer

  1. The power flow through a five-speed transmission while it is in first gear:
  1. Power enters on the input shaft, which rotates the countershaft that is engaged with first gear.

Fill in the Missing Words

  1. Place the missing word to complete the following statement about transaxle power flow using the following words.

Missing Words: differential, gear, output, rotate, selected, shaft, shift, synchronizer

When first gear is ______selected_________, the first/second gear synchronizer engages with first gear. Because the synchronizer hub is splined to the ________output_______ shaft, first gear on the input shaft drives its mating gear (first gear) on the output shaft. This causes the output shaft to ______rotate_________ at the ratio of first gear and to drive the differential ring _____synchronizer________ at that same ratio.

As the other forward gears are selected, the appropriate _________shift______ fork moves to engage the selected ____gear___________ with the gear. Because the synchronizer’s hub is splined to the output shaft, the desired gear on the input shaft drives its mating gear on the output ________shaft_______. This causes the output shaft to rotate at the ratio of the selected gear and drive the ______differential_________ ring gear at that same ratio.
