ASE A2 questions with correct answers
What is the purpose of a brake band? - Answer It stops and holds the drum that is
connected to a member of the planetary gearset.
What are brake bands made out of? - Answer Brake bands are flexible steel plates
lined with friction material. That material can be organic or semi-metallic.
What aids in brake band hear dissipation? - Answer The friction material absorbs
trans fluid.
When the brake band tightens around the drum, why doesnt trans fluid get trapped
in between the two surfaces? - Answer Trans fluid is squeezed out into grooves
cut in the lining.
What is the benefit of using a softer metal like iron for the drum? - Answer The
dimpled surface aids in both clamping force and heat dissapation.
How can you tell if a drum is made out of harder metal? - Answer The surface is
usually smooth.
What are the benefits of having a double wrapped band? - Answer Double
wrapped bands have more clamping force and require less hydraulic pressure to
produce the same amount of stopping power.
What happens as the brake band wears? - Answer A gap forms between the band
and drum, causing slippage.
What controls brake band application? - Answer A hydraulically controlled servo.
, What sets a clutch apart from a brake band? Why are they two separate style
components? - Answer Brake bands only stop and hold. Clutches stop, hold, and
drive.
Name three different components that automatic transmissions use to control and
lubricate the transmission. - Answer Pressure Regulator Valve
Governor Valve
Throttle Pressure Valve
Governor pressure increases with ___________. - Answer Vehicle speed.
What happens when governor pressure rises? - Answer The car will upshift.
What happens as throttle pressure rises? - Answer The car will downshift.
What does the pressure regulator valve control? - Answer Mainline pressure.
What does throttle pressure indicate? - Answer Engine load.
What are three way that different vehicles control the throttle valve? - Answer
Vacuum Modulator
Throttle Linkage
Electric Solenoid
Name three components of a governor valve. - Answer Springs
Centrifugal Weights
