ch 33

All of the following statements referring to transmission end play/preload are true except: end play and preload adjustments are a necessary part of the disassembly and assembly of the transmission. end play is the movement back and forth of the input or output shaft. Washer wear or bearing failure causes the shaft to walk back and forth in the case. axial or radial clearances should not determine whether gears and shafts are to be replaced or reused.

A car jumps out of gear into neutral when decelerating or going down hills. Tech A says that the shift lever and internal gearshift linkage should be checked. Tech B says that a detent spring could be broken. Who is correct?

both

Tech A says that broken or worn powertrain mounts can cause a transaxle to have shifting problems. Tech B says that poor shift boot alignment cannot cause a transaxle to jump out of gear. Who is correct?

both

Tech A says that the input shaft normally has to be installed before the main shaft. Tech B says that the countershaft is normally installed before the main shaft. Who is correct?

both

Transaxle inspection is being discussed. Tech A says that in some cases, a magnet is installed in the case to catch any ferrous metal particles, and it should be inspected. Tech B says that tapping on the gears with a ball-peen hammer and listening for a ringing sound is a good way to determine if a gear is reusable. Who is correct?

both

A transmission is being assembled, but the input shaft does not slide all the way in. Tech A says this is normal and to use the bolts to pull the front bearing retainer into place. Tech B says that you should use a hammer to tap the bearing retainer into place. Who is correct?

both,

Which tool is required to remove rear bearing race from the transmission case? Brass drift and hammer Seal driver Gear pullers Impact screw driver

brass drift and hammer

Choose the correct statement. Always reuse gaskets and seals. Sealants should not be used in transmissions. Gasket surfaces don't need to be cleaned because the new gasket will seal any residual gasket material. Check the main case and output shaft housing with a straightedge and feeler gauge.

All of the following statements with respect to disassembly of the transmission are true except: obtain and read all manufacturer publications and service information. diagnose the possible causes. ensure proper tools are available for disassembly and assembly. ensure that all transmission case components are replaced.

ensure that all transmission case components are replaced

Tech A says that as long as the dog (clutch) teeth of the synchronizer are rounded, the synchronizer can be reused. Tech B says that the synchronizer sleeve should slide smoothly on its splines. Who is correct?

neither

Tech A says that the condition of blocking rings should be checked by measuring the clearance between the blocking ring and the face of the gear. Tech B says that the blocking ring should be visually inspected for worn teeth and worn (smooth) internal surfaces. Who is correct?

neither

Transmission end play is being discussed. Tech A says that a micrometer should be used to measure the inward and outward movement of the output shaft. Tech B says that an angle gauge should be used to measure output shaft rotation. Who is correct?

neither

The selective thickness shims are measured with a(n): hydraulic press. outside micrometer. dial indicator. depth micrometer.

outside micrometer

Choose the correct statement. The transaxle final drive can be removed without disassembling the transaxle. The pinion gear is part of the input shaft of the transaxle. The pinion gear drives the differential ring gear, located inside the transaxle assembly. Do not replace the ring gear if the pinion gear has to be replaced.

Which of these tools is required to pull differential case bearings? Push-type bearing puller An old bearing race Chain-style vice grips Snap ring pliers

push-type bearing puller

Tech A says that a leaky transmission output shaft seal is likely to cause clutch plate contamination. Tech B says that a worn transmission rear bushing may contribute to output shaft seal leakage. Who is correct?

tech a

A rough growling noise occurs when the vehicle is moving and the transmission is in the forward or reverse gear. The noise is not heard when the transmission is in neutral. Tech A says that the output shaft (main shaft) bearings may be faulty. Tech B that says the pilot bearing may be faulty. Who is correct?

tech b

Which of the following could cause the transmission to make noise only when the clutch pedal is depressed? Worn input shaft bearing Worn synchronizer rings Throwout bearing Worn counter shaft bearing

throwout bearing

A good place to start when inspecting for synchronizer wear and damage is when the: transmission fluid is drained from the transmission. transmission is being assembled. vehicle is running. transmission endplay is measured and adjusted.

transmission fluid is drained from the transmission.

All of the following statements with respect to overhauling a transmission are true except: transmission case components should be cleaned and inspected when in doubt about the reusability of a case component, do not replace it. perform a cost analysis for the customer. if rebuilding will cost more than a remanufactured unit, the customer should be informed.

when in doubt about the reusability of a case component, do not replace it.
