Which strategy manages torque during a gearchange?

  • A.An increase in torque, which compensates for the interruption of the drive during the change of the gear ratio
  • B.No change
  • C.A momentary retard of the ignition timing commanded by the transmission controller, which smooths the engagement
  • D.A brief coordinated torque reduction

Answer: D

The transmission requests a reduction and the engine delivers it by retarding or cutting fuel. The last option describes exactly how that reduction is achieved, which makes it a correct and more specific statement. Reading the definition literally, rather than recalling a summary, avoids the usual confusion. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Tracing the requirement back to the physical constraint that produces it makes the answer follow.
