ASE Automatic Transmission/Transaxle 3

Question 1

A stall test that produces RPM well above specification indicates which problem?

Accepted Answer

Clutch or band slippage

Answer

Higher-than-spec stall RPM means the apply components are slipping and not transmitting full torque.

Question 2

A stall test RPM that is far below specification most likely points to which condition?

Accepted Answer

Engine not producing full power

Answer

Below-spec stall RPM usually means the engine cannot reach full torque output, not a transmission fault.

Question 3

What is the primary purpose of the torque converter stator?

Accepted Answer

Multiply torque at low speed

Answer

The stator redirects fluid back to the impeller, multiplying torque during acceleration.

Question 4

Delayed engagement when shifting from Park to Drive after the car sits overnight most likely indicates what?

Accepted Answer

Leaking pump or valve body allowing fluid drainback

Answer

Internal leakage drains pressure overnight, so it takes time to refill and engage when started.

Question 5

Which device on older transmissions senses vehicle speed hydraulically to help control upshifts?

Accepted Answer

Governor

Answer

The hydraulic governor develops pressure proportional to output shaft speed to signal upshifts.
