Many full hybrid vehicles can operate at low speeds using the electric motor only. These cars typically begin using the internal combustion engine at _________.

40 mph

Which of the following hybrid electrical systems uses a belt-driven alternator that also doubles as a starter?

Belt Alternator starter (BAS)

This feature, found in many scan tools, allows a technician to operate solenoids and actuators in a transmission

Bidirectional control

Two technicians are discussing gear set styles. Technician A says spur gears are loud and do not offer much strength. Technician B says helical gears offer the benefits of always having more than one gear tooth in contact with the driving gear, thus increasing the strength. Who is correct?

Both Tech A and Tech B

Technician A says modern automatic transmission cases are made of lightweight aluminum and alloys. Technician B says on the rear or output side of the transmission, there is an aluminum housing called the extension housing. Who is correct?

Both Technician A and Technician B

Which of the following could cause a vehicle being operated on a hoist to fall off?

Both tire damage and tire balance

If a transmission oil cooler ruptures and leaks, which of the following fluids could contaminate the transmission fluid?

Engine Coolant

Which of the following is typically the first step in diagnosis of an automatic transmission concern?

Fluid Check

Which of the following was used in early automatic transmissions?

Fluid Coupler

Which of the following vehicle manufacturers is the primary user of the belt alternator starter (BAS) system?

General Motors Corporation

Which of the following is a typical condition for torque converter lockup?

Light-Load higher speed

___________ can be either one-way rollers or sprag.

One-way clutches

When performing an automatic transmission fluid and filter change what should a technician look for in the bottom of the transmission pan that indicates potential transmission problems?

Sparkly metal flakes and dark residue

Technician A says antifoam additives help to prevent foaming of the transmission fluid. Technician B says viscosity modifiers cause the transmission fluid to be thick when cold and thin when hot. Who is correct?

Technician A

Technician A says on electronically controlled transmissions, the torque converter clutch (TCC) solenoid is monitored by the power train control module (PCM) and diagnostic trouble codes can be set when the TCC is not operating correctly. Technician B says on older hydraulically controlled transmissions, the PCM will set codes if the TCC solenoid is physically stuck closed. Who is correct?

Technician A

Technician A says there are many types of internal seals for an automatic transmission. Technician B says a square-cut seal is usually made from cork. Who is correct?

Technician A

Technician A says transmission repairs that can be done without removing the transmission include the replacement of external gaskets and seals. Technician B says transmission repairs that can be done without removing the transmission include the replacement of bands and clutches. Who is correct?

Technician A

Technician A says the parking pawl prevents the transmission's input shaft from rotating. Technician B says the vehicle may have to roll an inch or two for the parking pawl to engage. Who is correct?

Technician B

Technician A says you can clean a transmission cooler and lines using the shop's parts cleaning tank. Technician B says you can clean a transmission cooler and lines with an aerosol flushing kit. Who is correct?

Technician B

Two technicians are discussing electronically controlled automatic transmissions. Technician A says a multimeter is used to pull trouble codes from most vehicles. Technician B says you should follow the diagnostic step by step process until you have completed the diagnostic procedure and found the cause of the diagnostic trouble code (DTC). Who is correct?

Technician B

Why is it important to know the functions of a hybrid vehicle and how it operates?

To know the precautions you should take

What is the purpose of a vehicle's transmission?

integrated motor assist (IMA)

Which of the following is typically used when performing an in-vehicle diagnosis of an automatic transmission?

scan tools and pressure gauges

The ___________ is used to install a new transmission seal in the housing.

seal instillation tool

When servicing an automatic transmission, it may be necessary to adjust the _________ along with the transmission range sensor.

shift linkage

Automatic transmission fluid is _______ and even after you wipe it off of your hands, a film remains.

slippery
