178 Manual Drive Trains and Axles Copyright by Goodheart-Willcox Co., Inc. ASE-Type Questions—Chapter 8 1. Each of the following is found in manual transmissions except: (A) input shafts. (B) output shafts. (C) countershafts. (D) stator shafts. 2. Rearward movement of the input shaft is usually prevented by _____. (A) snap rings (B) the output shaft (C) the main drive gear (D) the front bearing retainer 3. Which of the following gears is used for reverse? (A) Spur gears. (B) Helical gears. (C) Cluster gears. (D) Main drive gears. 4. Which of the following contains the gears that provide all forward speeds and reverse? (A) Input shaft. (B) Clutch shaft. (C) Output shaft. (D) Reverse idler shaft. 5. Technician A says that each mainshaft gear comprises two sets of teeth. Technician B says that the main drive gear has three sets of teeth. Who is right? (A) A only. (B) B only. (C) Both A and B. (D) Neither A nor B. 6. To shift from one gear to another, constant-mesh manual transmissions require _____. (A) idler gears (B) bearings (C) planetary gears (D) synchronizers 7. Technician A says that the outer sleeve of a synchronizer assembly does not rotate until it engages the blocking ring. Technician B says that shift forks move the outer sleeve while permitting sleeve rotation to continue. Who is right? (A) A only. (B) B only. (C) Both A and B. (D) Neither A nor B. 8. In an internal shift linkage, which of the following locks out all other gears except the one selected? (A) Locknut. (B) Blocking ring. (C) Interlock plate. (D) Block synchronizer. 9. In reverse gear, rotation between input and output shafts is reversed _____. (A) once (B) twice (C) three times (D) five times 10. On a fully synchronized transmission in Neutral, each of the following is driven by the main drive gear except: (A) second gear. (B) the reverse idler gear. (C) the countershaft gear. (D) the output shaft. or to prevent starting the engine when the transmission is in gear. Sensors are used to provide information to engine con- trol computers. Solenoids help control transmission shifting. There are many different kinds of rear-wheel drive manual transmissions. Models with only three forward speeds are obsolete and will be found only in very old vehicles. The 4- and 5-speed models are the most common today. The 6-speed model is increasingly being used to obtain accept- able gas mileage on high-performance vehicles.

The _____ supports the transmission shafts, forms a reservoir for lubricant, and provides an attaching point for other components. 3. The _____ provides protection for the end of the transmission output shaft and is the usual location for the transmission mount. 4. The four types of transmission shafts are the _____ shaft, _____, _____, and _____ shaft. 5. Why are thrust washers used in transmissions? 6. To lock mainshaft gears to the output shaft and eliminate gear clash in the process, constant-mesh transmissions use _____. 7. In your own words, how do synchronizers operate? 8. Each _____ gear comprises two sets of teeth. 9. In an internal shift linkage, shifting is accomplished by means of a(n) _____ _____ attached to a _____ shaft. 10. What types of lubricant are used in a manual transmission?
