Automatic Transmission Questions and Answers

Answer: A

A torque converter transmits drive from the engine and holds nothing within the gear train. Bands, multi-plate brakes and sprag clutches all anchor a member so the set can produce a ratio. The converter sits ahead of the gearing entirely. Tracing the requirement back to the physical constraint that produces it makes the answer follow. Checking which component actually carries the load settles most questions of this kind at once.

Answer: B

The pawl locks the driven wheels mechanically and works whether or not there is hydraulic pressure. Applying the parking brake before selecting park keeps the load off it, which matters greatly on a steep gradient. The shared behaviour explains why these belong together and the differences explain why both exist. Tracing the requirement back to the physical constraint that produces it makes the answer follow.

Answer: C

A monostable switch or rotary dial sends a signal and an actuator moves the manual valve, which frees console space. Cable selectors remain very common and do need adjustment, which makes the second option wrong only in its final clause. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. The shared behaviour explains why these belong together and the differences explain why both exist.

Answer: D

A lever returning to a central rest position gave no tactile confirmation of the gear, and rollaway incidents followed. Automatic park on shutdown and clearer displays were the response. It led to a large recall. 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.

Answer: A

Controllers now select park automatically when the engine is stopped or the driver's door is opened with the vehicle stationary. Automatic parking brake application genuinely accompanies it, which makes the last option a real part of the same solution. Most errors here come from carrying across a result from a neighbouring case where it does not hold. Reading the definition literally, rather than recalling a summary, avoids the usual confusion.

Answer: B

The shift lock solenoid releases only when the brake pedal is pressed with the ignition on. The knob button is a mechanical detent and does contribute, which makes the last option a real feature that is not the interlock itself. A manual override is provided for a flat battery. Naming what changes and what stays the same is the reliable route through questions of this shape. Most errors here come from carrying across a result from a neighbouring case where it does not hold.

Answer: C

A small covered slot near the lever accepts a key or screwdriver to release the lock so the vehicle can be moved. The procedure is in the handbook. Without it a flat battery would leave the vehicle immovable. Working the distinction through on a single concrete case fixes it more firmly than any rule of thumb. Naming what changes and what stays the same is the reliable route through questions of this shape.
