Technician A says the gears in a planetary gearset are in constant mesh. Technician B says a planetary gearset has a ring gear and pinion gears. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

Technician A says that one planetary gear set can provide gear reduction, overdrive, and reverse. Technician B says that most transmissions today use compound (multiple) planetary gear sets. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

Automatic transaxles include a ________ in addition to the planetary gear sets.

• transversal

• dry clutch

• differential assembly

• spur gear

During which of these conditions is the torque converter clutch engaged?

• At speeds over 25 MPH

• During acceleration from a stop

• During acceleration at highway speeds

• None of these

Using a torque converter smaller than stock size could result in ________.

• Slower than normal acceleration

• Faster than normal acceleration

• Reduced fuel economy

• Both B and C

A CVT changes gear ratios by changing the diameter of the ________.

• torque converter

• planetary gear set ring gear

• drive and driven pulleys

• output gear

The torque converter clutch increases efficiency by ________.

• allowing quicker starts in first gear

• eliminating converter slippage

• disconnecting the torque converter from the engine at a stop

• none of these

Technician A says automatic transmissions can shift gears without requiring an interruption of powerflow. Technician B says automatic transmissions use synchronizers instead of planetary gearsets. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

Two technicians are discussing automatic transmissions/transaxles. Technician A says that it is normal for a vehicle to move slightly when the gear selector is in the 'drive' position with the brakes released. Technician B says that the stator may be defective if the vehicle moves while in gear when the engine is at idle speed. Which technician is correct?

• Technician A only

• Technician B only

• Both technicians

• Neither technician

What is the purpose and function of a lock-up part of the torque converter?

• Improves fuel economy by eliminating slippage

• Increases vehicle performance by allowing more torque multiplication

• Allows the transmission/transaxle to shift faster

• Increases fluid pressure in the transmission/transaxle
