LV13 Quiz 2

What is component 'C' in the fluid coupling diagram referred to as?

• Turbine connected to the transmission input shaft

• Turbine connected to the engine crankshaft

• Impeller and is connected to the transmission input shaft

• Stator and multiplies the torque output of the turbine

What is one possible cause for a manual transmission vehicle not disengaging the clutch?

• Worn clutch pressure plate

• Contaminated clutch linings

• Broken centre plate torsional springs

• Centre plate sticking on input shaft splines

What action does a traction control system take when it senses wheel slip?

• Limits the engine RPM and brakes the slipping wheel

• Reduces the engine RPM and brakes both wheels

• Automatically brakes the parallel driving wheel

• Stops the ABS modulator from working

The gearbox shown has no drive in 5th gear. Which two gears should be checked?

• B & C

• H & J

• A & Q

• I & K

When engaging gear there is noticeable clutch judder. ONE possible cause is:

• badly worn engine mountings

• clutch cable worn

• centre plate sticking on input shaft splines

• broken clutch diaphragm spring

Which one of the following statements is FALSE?

• The final drive ratio increases the torque to the road wheels and reduces speed

• Rapid knocking noise when cornering is a defective CV joint

• The final drive turns the drive through a right angle on front wheel drive vehicles

• A viscous coupling can be used as the third differential in a 4WD system

A vehicle fitted with manual transmission crashes when engaging 2nd gear. The most likely cause is:

• Spigot bearing partially seized on input shaft

• Defective gear interlocking device

• Worn synchromesh baulk ring

• Seized clutch release bearing

• Impeller and has curved blades

• Stator and is attached to a one-way clutch

• Turbine and has straight blades

• Turbine and has curved blades

Which one of the following is a true advantage of using electronic transmission control?

• There is no requirement for a hydraulic governor

• It requires specialist software to retrieve fault codes

• It increases the engine torque output

• It increases the overall fuel consumption

Which gears are involved in obtaining the first gear in a light vehicle transmission?

• I & K

• E & G

• D & F

• B & C
