✍️ Sample ASE A2 Questions & Answers
1. During inspection of a clutch drum, a technician finds that the check ball in the piston area is stuck in its seat. What problem can this cause?
The check ball opens to dump trapped fluid when apply pressure drops. If it sticks, centrifugal pressure may keep the clutch partly applied.
2. While inspecting a gear-type oil pump, a technician needs to measure gear end clearance. Which method is correct?
End clearance is the gap between the gear face and a straightedge laid on the pump body. A feeler gauge measures that gap, and the reading is compared to specification.
3. When air testing an assembled clutch drum by directing compressed air into its apply passage, which result points to a failed piston seal?
If the piston seals leak, air escapes and the piston cannot build enough force to move. A good clutch applies with a dull thud and releases when air is removed.
4. While checking fluid on a torque converter automatic, a technician finds the fluid on the dipstick is pink and milky. Which is the most likely cause?
A milky, pink appearance indicates water or coolant contamination, commonly from an internal leak in the cooler inside the radiator tank. Overfill leads to foaming, not a milky color caused by coolant.
5. A vehicle clunks and the engine visibly rocks each time the shifter is moved from Park to Drive. The transmission shifts normally otherwise. Which component should be inspected first?
Excessive engine movement at engagement points to worn or broken engine or transmission mounts.
6. A technician uses scan tool data to divide turbine (input) speed by output shaft speed while the transmission is commanded into a gear. What is the main reason for this calculation?
The input-to-output speed ratio gives the actual gear ratio, which can be compared to the specified ratio for the commanded gear. A mismatch indicates slip in an apply element.
