Exam 16: Standard Transmission Servicing

Technician A says that when range slipout occurs,the transmission air pressure regulator may require adjustment.Technician B says that range slipout can be caused by a leaking air hose.Who is correct?

Technician A says that some bolt holes used to couple flanges and manifolds to the transmission,bore through the housing and can potentially leak oil.Technician B says that thread sealant should be used on fasteners used to couple flanges and manifolds to transmissions.Who is correct?

Technician A says that a mechanical road speed signal is driven off the input shaft of a standard transmission.Technician B says that an inductive type road speed sensor picks up its signal from the tailshaft of the transmission.Who is correct?

When a yoke seal race is damaged,which of the following is the cost-effective repair method?

Approximately where is the auxiliary drive gear usually located in a typical truck,twin-countershaft transmission?

Which of the following problems would be more likely to cause a twisted mainshaft?

Which of the following driver related conditions would be more likely to result in a twisted input shaft?

Technician A says that a new transmission filled with Eaton E-500 lubricant does not require an initial break-in drain and fill after the first 3,000 to 5,000 miles of service.Technician B says that E-250 lubricant is rated for service intervals of up to 250,000 linehaul miles.Who is correct?

When a mineral-based transmission lubricant is used which of the following would be the usual recommended oil change interval under normal highway operating conditions?

Technician A says that it is usual to mark two adjacent gear teeth on a countershaft gear for timing purposes.Technician B says that it is usual to mark a single mainshaft gear tooth for timing purposes.Who is correct?

When heating a bearing prior to installation,which of the following is the recommended method of ensuring that it is not over-heated?

Technician A says that a no range shift condition could be caused by cracked slave valve piston.Technician B says that to repair a cracked range shift piston,the compound (auxiliary section)must be removed.Who is correct?

When assembling a ten-speed,twin-countershaft transmission which of the following must be timed?

Which of the following would be the MOST LIKELY cause of air leakage from the range valve when in high range only?

If the air lines between the slave valve and the range cylinder are crossed,what would be the MOST LIKELY result?

On a typical truck twin countershaft transmission,which of the following components would have to be removed to replace a damaged input shaft?

Technician A says that slow range shifts may be caused by dry (insufficient silicone lube)O-rings.Technician B says that slow range shifts can be caused by excessive silicone lube applied to O-rings.Who is correct?

Which of the following could cause a twisted mainshaft?

Which of the following would be the MOST LIKELY cause of a transmission housing that becomes pressurized in low range only?

When attempting to identify the source of contaminants in transmission lube,which of the following are possible?
