Level 3 Transmissions IMI

why do we carry out a stall test on an automatic gearbox.

• To check for torque converter and Transmission clutch slip
• to check the braking system is working correctly
• to check sun and planet gears are engaged
• to check the ignition system is working correctly

In an automatic transmission gearbox Kick down happens when

• pulling away from standstill
• Accelerating hard
• Cruising
• Accelerating gently

In a gearbox when the larger gear drives the smaller driven gear

• Underdrive is taking place
• Torque output is reduced and speed output is increased
• the gear ratio will be greater than 1:1
• Torque output is increased and speed output is reduced

Solenoids in an electronic gearbox, are operated by a

• Governor
• fresh air
• Electronic control unit. (ECU)
• There are no solenoids in an automatic gearbox

The loads mostly transmitted by any gearbox are

• shear
• compressive
• linear
• Torsional

what does CVT transmission stand for

• Constantly vibrating transmission
• continually viable transmission
• Constantly variable transmission
• constant viscous transmission

A constantly variable transmission consists of

• a matched gear set
• A chain driven cog
• 3 forward and a reverse gear
• a belt and variable pulley arrangement

which of the following is NOT true

• E gearbox faults may have a fault code read by a scanner
• ATF is used to fill an automatic gearbox
• Electric signals in an auto can be checked byoscilloscopes
• the impellor of a torque converter contains straight vanes

A high revving, high in torque clutch will use

• Metal only friction plates
• A multi plate clutch
• A toughened cover plate
• A Vee belt and Pulley arrangement

During a service you find burnt brown automatic transmission fluid in a gearbox it shows

• incorrectly meshed gears
• No transmission faults are present
• A slipping clutch
• Torque converter is detached from the input shaft
