Which condition must be met before a lock-up clutch engages?

  • A.The transmission fluid at its minimum operating temperature, below which the clutch cannot generate sufficient friction
  • B.Adequate road speed with a stable, light throttle
  • C.Full throttle, since the clutch is engaged in order to transmit the maximum torque without the loss of slip
  • D.Any condition

Answer: B

Lock-up is applied only when the engine is not being asked to accelerate hard, because the converter's damping is lost when it engages. Fluid temperature is genuinely used as a condition on many systems, which makes the last option a real consideration. The shared behaviour explains why these belong together and the differences explain why both exist. Most errors here come from carrying across a result from a neighbouring case where it does not hold.
