Transmission Service Part A Flashcards
Explain the procedure to correctly check the transmission fluid level.
Clean the dirt away from the filler plug. While checking level oil must be level with the bottom of the filler plug opening.
Leaking output shaft seals, worn output shaft bearings and broken synchronizer pins are often an indication of a problem with the:
a. engine and transmission mounts.
b. clutch system
c. driveline
d. shift mechanism
c. driveline
Hard shifting can generally be contributed to two things What are they?
a. external shift linkage
b. internal transmission components
A power takeoff with insufficient backlash or uneven wear patterns caused by mismatched gear sets will cause what type of transmission noise?
a. knocking or thudding.
b. whine or squeal
c. growling
b. whine or squeal
Why must the mating driveline parts be carefully marked before you disconnect the driveline?
Replacing the components in exactly the marked position ensures that the driveline phasing and balancing will not be changed.
During the disassembly process, it is not necessary to mark the location of components such as the countershafts as they are identical and cannot be installed improperly.
True
False
False
Alternate welding and tearing at the gear teeth due to an insufficient film of oil results in:
a. healing
b. pitting
c. spalling
d. scoring or galling
d. scoring or galling
On a selective mainshaft assembly, improper shimming could result in which two failures?
a. too little running clearance between the mainshaft gears. Provides no lubrication.
b. Too much clearance can cause rattling and excessive vibrations.
Improper installation of the dowels between the main housing and the auxiliary housing will lead to:
A misalignment problem and accelerated wear on components.
Premature input shaft bearing failure or slip out in direct gear is often an indication of a problem with the:
a. engine and transmission mounts.
b. clutch system.
c. driveline.
d. shift mechanism.
a. engine and transmission mounts.
Slip out tends to occur during normal driving conditions or rough road conditions.
True
False
False
Worn input shaft splines that do not let the clutch fully release, causes gear clashing in which gears?
a. reverse
b. first
c. direct
d. overdrive
e. reverse and first
e. reverse and first
The temperature of the transmission oil should not exceed 250 degrees Fahrenheit on a constant basis.
True
False
True
A visual inspection process is an integral part of the transmission disassembly procedure.
True
False
True
Frosting and offset frosting are both examples of gear wear that is abnormal and would result in gear replacement at time of overhaul.
True
False
False
