It ensures that the fluid is at the correct pressure to allow for smooth shifting of gears and proper operation of the transmission. By regulating the pressure, the pressure regulator valve helps to prevent damage to the transmission components and ensures optimal performance.

In planetary gear sets, when the sun gear is held stationary, the internal ring gear becomes the driving member and the planet carrier becomes the driven member. In this configuration, the gear set achieves the minimum reduction, meaning that the output speed is lower than the input speed. This is because the planet gears rotate around the sun gear and mesh with both the sun gear and the internal ring gear, causing a reduction in speed.

The correct answer is the Converter feed limit valve. The converter feed limit valve is responsible for producing line pressure in the transmission system. It controls the flow of fluid to the torque converter, which in turn generates the necessary pressure for the transmission to function properly.

This design helps to reduce friction and ensure smooth movement between the trunnion and bearing cap, making the needle bearing the correct answer in this case.

The term "removable carry axle housing" refers to an axle housing where the ring and pinion gears can be taken out of the housing as a single unit. This means that the gears are not permanently fixed within the housing and can be easily removed for maintenance or repairs. In contrast, an integral carry axle housing would indicate that the gears are permanently fixed within the housing and cannot be easily removed.

A locking differential is the correct answer because it is mostly used in off-road and racing applications where both drive axles receive the same amount of torque. This type of differential locks the two wheels on an axle together, ensuring that they both rotate at the same speed. This is beneficial in situations where maximum traction is required, such as when driving on uneven or slippery terrain. By locking the wheels together, the locking differential allows for better power distribution and improved off-road performance.

A good example to think about fluid coupling is when the input fan and output fan are blowing air pressure at one another. In a fluid coupling, the input fan and output fan are connected by a fluid-filled chamber. When the input fan blows air pressure into the chamber, it creates a force that is transferred to the output fan, causing it to rotate. Similarly, when the output fan blows air pressure into the chamber, it creates a force that is transferred back to the input fan. This arrangement allows for the transfer of power between the input and output fans without any direct mechanical connection.

When the internal ring gear and sun gear are driving members and the planet carrier is the driven member, it means that the gear set is rotating as a single unit. In this configuration, the input and output speeds are equal, resulting in a direct drive. This means that there is no reduction or increase in speed, and the output speed matches the input speed.

The pressure regulator valve is responsible for creating line pressure in a hydraulic system. It controls the flow of fluid and maintains a consistent pressure level throughout the system. By adjusting the valve, the pressure can be increased or decreased as needed. This ensures that all components in the system receive an adequate amount of fluid under the correct pressure, allowing for proper operation.

Accumulators in a clutch apply circuit play a crucial role in controlling shift feel and shift timing. They consist of a piston and a reservoir, and their purpose is to act as shock absorbers, ensuring smooth engagements during gear shifts.

The correct answer is the inside wheel. In a vehicle, especially during a turn, the inside wheel travels a shorter distance compared to the outside wheel. To compensate for this, the inside wheel needs to rotate at a slower speed than the outside wheel. This helps maintain stability and prevents skidding or slipping during turns.

The given hint suggests that the ratio of driven teeth to driving teeth is 2:1. This ratio is commonly referred to as the gear ratio, which represents the relationship between the number of teeth on the driven gear and the number of teeth on the driving gear. Therefore, the correct answer is "Gear ratio."

A hypoid gear is a type of gear where the centerline of the pinion gear is located below the centerline of the ring gear. This design allows for a larger gear ratio and smoother operation compared to other types of gears. The offset centerline of the pinion gear in a hypoid gear allows for better power transmission and torque distribution, making it suitable for applications that require high torque and low noise.

The torque converter generates heat in the fluid. The torque converter is a component in an automatic transmission that transfers power from the engine to the transmission. It uses hydraulic fluid to transmit power, and as the fluid circulates through the torque converter, it generates heat due to friction and the mechanical processes happening inside. This heat is then dissipated through the transmission cooler to prevent overheating of the fluid and maintain optimal operating conditions.

The gears in a planetary gear set with external teeth rotate in opposite directions. This is because the power is transmitted through the meshing of the teeth, and the rotation of one gear causes the other gear to rotate in the opposite direction. This configuration allows for different speed ratios and torque outputs in a planetary gear system.

A semi-floating axle assembly has the bearing located inside the axle housing, and the axle shaft carries the vehicle weight. This type of axle assembly is commonly used by light trucks and rear-wheel drive passenger cars. Unlike a full-floating axle assembly where the axle shaft only transmits torque, in a semi-floating axle assembly, the axle shaft also supports the weight of the vehicle.

When the sun gear is held stationary, the planet carrier becomes the driving member, and the internal ring gear becomes the driven member. In this configuration, the sun gear acts as a counter gear, which means it rotates in the opposite direction to the planet carrier. This arrangement is known as overdrive, which refers to a gear ratio that allows the output speed to be higher than the input speed.

A limited slip differential is a type of differential that is designed to provide torque to the wheel with more traction and limit torque to the wheel with less traction. It achieves this by using various designs such as torque sensing, viscons, and cone clutch types. This allows for better traction and control, especially in situations where one wheel may be slipping or losing traction. Unlike an open differential, which allows the wheel with less traction to spin freely, a limited slip differential helps to distribute torque more evenly between the wheels, resulting in improved performance and stability.

A bearing splitter is a component that is specifically designed to pull bearings off a shaft. It is a tool that consists of two halves that can be placed around the bearing, and then tightened together using screws or bolts. This creates a separation between the bearing and the shaft, allowing the bearing to be easily removed without causing any damage. A screwdriver, on the other hand, is a general-purpose tool that is not specifically designed for bearing removal and may not provide the necessary grip or leverage to safely remove a bearing from a shaft.

The pump is the main source of pressurized fluid in the hydraulic system. It is responsible for creating the necessary pressure to operate the system by drawing in fluid and then forcing it through the system. Without the pump, there would be no pressurized fluid available for the system to function properly.

A grease seal is a component that fits on the end of the bearing cap and is responsible for maintaining lubrication. It prevents grease from leaking out of the bearing and keeps dirt and contaminants from entering, ensuring that the bearing remains properly lubricated and protected.

The correct answer is "Converter feed valve." In automatic transmission operation, fluid enters the torque converter from the converter feed valve. This valve controls the flow of fluid into the torque converter, allowing it to transfer torque from the engine to the transmission. Without the converter feed valve, the torque converter would not be able to function properly, leading to transmission issues.

The correct answer is pinion shaft. The question is asking about the rotation of differential pinion gears, and the pinion shaft is the component on which these gears rotate. The side gear is another component of the differential system, but it does not rotate the pinion gears. Similarly, the pinion gear is one of the gears that rotate on the pinion shaft, but it is not the correct answer. The axle assembly is not directly related to the rotation of the pinion gears.

When using a bearing splitter, it is important to take safety measures. The correct answer states that the support should be placed parallel with the bolts and supported with the clamp bolts. This ensures that the bearing splitter is securely held in place and prevents any accidents or injuries while removing the axles assembly from the vehicle. Placing the support parallel with the bolts provides stability and allows for a safe and effective removal process.

In a hunting gear set, all ring gear teeth come in contact with all pinion teeth. This means that as the gears rotate, each tooth on the ring gear engages with each tooth on the pinion gear, ensuring smooth and continuous contact between the gears. This type of gear set is commonly used in applications where quiet and efficient operation is required, such as automotive differentials.

The governor is responsible for regulating the speed of the vehicle. It acts as a hydraulic speedometer and is driven by either a shaft or gears. It controls the vehicle's speed by adjusting the flow of hydraulic fluid to the up or down shaft.

The differential pinion gears walk on the slower side gear. In a differential system, the pinion gears are responsible for transferring power from the driveshaft to the side gears. As the vehicle turns, the side gears rotate at different speeds. The pinion gears walk on the slower side gear to allow for this speed difference and ensure smooth operation of the differential.

A limited slip differential transfers torque to the wheels with less traction, allowing for better traction and control in situations where one wheel may be slipping or losing traction. Unlike an open differential which allows the wheel with less traction to spin freely, a limited slip differential uses a mechanism to limit the speed difference between the two wheels, ensuring that power is still transferred to the wheel with more traction. This helps improve the vehicle's stability and performance, especially in off-road or slippery conditions. A locking differential, on the other hand, completely locks the two wheels together, providing equal torque to both wheels regardless of traction, which can be useful in extreme off-road situations.

In a planetary gear set, the reverse configuration occurs when the planet carrier is held stationary, the sungear is the driving member, the internal ring gear is the driven member, and the planet pinion gear acts as an idler gear. This arrangement causes the output shaft to rotate in the opposite direction compared to the input shaft, hence the term "reverse."

The given statement mentions that the center of the u-joint and machined surface is called trunnions. However, the options provided do not include the term "trunnions". Among the given options, the component that is commonly found in a u-joint and is typically located at the center is the "Cross". Therefore, the correct answer is "Cross".

The fluid enters the manual valve from the pressure regulator valve. The pressure regulator valve is responsible for controlling the pressure of the fluid in the transmission system. It ensures that the fluid pressure is at the correct level for proper operation of the transmission. The manual valve, on the other hand, is responsible for directing the flow of fluid to the appropriate components within the transmission based on the position of the gear selector. Therefore, the fluid enters the manual valve from the pressure regulator valve.

The outside side gear rotates faster than the inside side gear.

The correct answer is "Cooler." After passing through the torque converter, the hot fluid is directed to the cooler circuit, where it is cooled down before being circulated back into the system. The cooler plays a crucial role in maintaining the optimal temperature of the fluid, preventing overheating and ensuring the efficient operation of the torque converter. The other options, such as the oil to water cooler and auxiliary cooler, are not specifically mentioned in the question and therefore cannot be considered as the correct answer.

The pinion shaft in an open differential fits into the machined holes, is retained by a roll pin, and turns with the case. The pinion shaft is responsible for transmitting torque from the driveshaft to the ring gear, allowing the wheels to rotate at different speeds during turns. It is an essential component that ensures smooth and efficient power distribution in the differential system.

The correct answer is the fourth character. In alphanumeric transmission code, the fourth character represents the control type. It can be one or more letters depending on the application.

In an automatic transmission, the manual valve controls the flow of fluid to different circuits based on the gear selected. When the transmission is in first gear, the manual valve directs the fluid to the shift valve and forward clutch feed circuits, allowing the transmission to engage the forward clutch and move the vehicle in first gear. Therefore, the fluid enters the shift valve and forward clutch feed circuits through the manual valve in first gear.

The stator in a torque converter is responsible for allowing the torque converter to multiply torque. It redirects the flow of fluid in the torque converter, causing the fluid to change direction before it reaches the turbine. This change in direction creates a force that helps to increase the torque output of the torque converter.

When the fluid spikes the turbine, it rotates the turbine in the same direction as the impeller. The impeller is a component of the turbine that is responsible for drawing in and accelerating the fluid. As the fluid flows through the impeller, it creates a force that causes the impeller to rotate. This rotational motion is then transferred to the turbine, causing it to rotate in the same direction as the impeller. Therefore, the correct answer is Impeller.

The correct answer is Rotary flow because the blades of the impeller inside the torque converter create a rotational force, causing the fluid to move in a circular or rotary motion. This type of flow is commonly observed in devices such as pumps, turbines, and impellers, where the fluid is pushed or pulled in a circular path.

When canceling angles in a U-joint, the operating angle of one U-joint is offset by the operating angle of the other U-joint. This means that the two U-joints work in conjunction to cancel out any angular misalignment between the driving and driven shafts. Therefore, the correct answer is "Other U-joint" because it is the U-joint that offsets the operating angle of the first U-joint.

The auxiliary cooler reduces fluid temperature, indicating that it is a part of the system that helps cool down the fluid. The term "lube circuit" refers to the lubrication system in a machine or engine, which includes the circulation of oil to various components for lubrication purposes. Therefore, the fluid is now in the lube circuit after passing through the auxiliary cooler.

The front U-joint measures the difference between the output shaft angle and the driveshaft angle. This means that it calculates the variation between the angles at which the output shaft and the driveshaft are positioned.

Non-planetary transmissions provide four or more forward gears.

The oil to water cooler cools the hot fluids, and after that, the fluid passes through the axillary cooler. The axillary cooler is an additional cooling device that helps to further lower the temperature of the fluid before it is circulated back into the system. It is an essential component in maintaining the optimal temperature and preventing overheating in the system.

The shift valve is responsible for controlling the flow of line pressure to the servo circuits in order to apply the band. It directs the pressure to the appropriate servo circuit, which then applies the band to the desired component, such as the input shaft. Therefore, the correct answer is the shift valve.

The vortex flow is generated as the fluid from the turbine flows to the impeller. The impeller is a rotating component that acts as a pump, drawing in the fluid and then expelling it with force. As the fluid is expelled from the impeller, it creates a swirling motion known as vortex flow. This vortex flow is important for efficient fluid transfer and is a key aspect of the turbine's operation.

The forward clutch drum in a basic automatic transmission has a drum that encloses all the components. The steel plates lock into the drum, and the apply plates alternate between steel and friction plates. The apply piston moves back and forth, and the pressure plate stops the discs when the clutch is engaged. The release spring pushes the piston away when the clutch is disengaged. Therefore, the correct answer is the forward clutch drum.

The sun gear is driven by the forward clutch. In an automatic transmission, the sun gear is one of the main components that helps to transfer power from the engine to the wheels. It is connected to the input shaft and meshes with the planetary gears, allowing for different gear ratios to be achieved. By engaging the forward clutch, the sun gear is able to drive the other gears and ultimately determine the gear ratio for the transmission.

The slip yoke is a component of the U-joint that connects the transmission to the driveshaft. It is responsible for transferring the rotational force from the transmission to the driveshaft. The slip yoke is connected to the trunnions of the Cross, which are attached to the driveshaft. As the slip yoke rotates, it causes the trunnions to rotate as well, thus transmitting the rotational force to the driveshaft. This allows power to be transferred from the transmission to the driveshaft at an angle, enabling the driveshaft to rotate and ultimately drive the wheels of the vehicle.

Planetary gear sets consist of three main components: a sun gear, a ring gear, and multiple planet gears. The planet gears are meshed with both the sun gear and the ring gear. When the sun gear rotates, it causes the planet gears to rotate as well. The ring gear remains stationary. In this configuration, the planet gears rotate in the same direction as the sun gear, but at a different speed due to the varying number of teeth. Therefore, the correct answer is "Same direction."

Thrust washers are components in an open differential that sit between each differential gear and the case. They are designed to prevent wear by providing a smooth surface for the gears to rotate against. The thrust washers help distribute the load and reduce friction between the gears and the case, ensuring smooth operation and preventing excessive wear and damage to the differential components.

The explanation for the correct answer, Vortex flow, is that the circulation of fluid in this scenario is caused by the fluid leaving the impeller and going to the turbine, and then returning back to the impeller. This circulation occurs due to the difference in rotation between the impeller and the turbine. Vortex flow refers to the swirling motion of fluid, which is a characteristic of this circulation pattern.

The rules of planetary gear sets state that either the sun gear or the ring gear is the held member, while the planet pinion gears rotate around the stationary member. This means that either the sun gear or the ring gear remains fixed while the planet pinion gears revolve around it.

The correct answer is Drive shaft. In the phasing of u-joints, the alignment of the input yokes of the drive shaft is crucial. The drive shaft connects the transmission to the differential and transfers torque from the engine to the wheels. Proper alignment of the input yokes ensures smooth power transfer and prevents vibrations or damage to the drivetrain components.

The correct answer is mechanical system because all the components mentioned in the question are part of a mechanical system. A torque converter, gear train, input shaft, output shaft, bearings, thrust washers, and apply components are all mechanical parts that work together to transmit power from the engine to the wheels.

Differential pinion gears are the components in an open differential that are held by the pinion shaft and mashed with the differential side gears. These gears play a crucial role in distributing torque between the two wheels of the vehicle, allowing them to rotate at different speeds during turns. By meshing with the side gears, the pinion gears transfer power from the engine to the wheels, ensuring smooth and controlled operation of the vehicle.

At coupling speed, the turbine and impeller are rotating at almost the same speed. This is because the coupling is a device used to connect the turbine and impeller, allowing them to transfer power and rotate together. Therefore, when the coupling speed is reached, it indicates that both the turbine and impeller are rotating at nearly identical speeds.

An inclinometer is used to check the angle of a driveshaft. This device measures the angle of inclination or tilt relative to the horizontal plane. By using an inclinometer, one can determine the angle at which the driveshaft is positioned, which is important for ensuring proper alignment and operation of the driveshaft in a vehicle or machinery.
