LV13 Paper 2

The picture shows a type of fluid coupling.

• turbine and is connected to the transmission input shaft

• turbine and is connected to the engine crankshaft

• impeller and is connected to the transmission input shaft

• stator and multiplies the torque output of the turbine

A vehicle with a manual transmission will not disengage the clutch. ONE possible cause is a:

• worn clutch pressure plate

• contaminated clutch linings

• broken centre plate torsional springs

• centre plate sticking on input shaft splines

When a traction control system senses wheel slip it will:

• limit the engine RPM and brake the slipping wheel

• reduce the engine RPM and brake both wheels

• automatically brake the parallel driving wheel

• stop the ABS modulator working

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

• B & C

• H & J

• A & Q

• I & K

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

Component 'A' in the diagram is the:

• impeller and has curved blades

• stator and is attached to a one-way clutch

• turbine and has straight blades

• turbine and has curved blades

The picture shows a light vehicle transmission. First gear is obtained by gears:

• I & K

• E & G

• D & F

• B & C

The picture shows a simple epicyclic gear train. In an automatic gearbox, it is conventional practice for the epicyclic gear train shown to:

• provide two reverse gears and one forward gear

• provide two forward gears and one reverse gear

• be coupled with a fluid flywheel to provide torque multiplication

• be coupled with other epicyclic gear trains to provide more forward gears

A typical gear ratio for 4th gear, in a five speed gearbox is:

• 0.56:1

• 1.00:1

• 1.43:1

• 2.07:1

In relation to a vehicle, what does the abbreviation 'VIN' mean?

• Vehicle Information Number

• Vehicle Identification Number

• Vehicle Interpretation Number

• Vehicle Introduction Number
