The A2 exam has 55 questions and runs 1 hours 15 minutes.
A transaxle is equipped with a fluid level/check plug and no dipstick. Which condition must be met before the fluid level reading is considered valid?
Correct answer: A - The fluid must be within the temperature range specified by the manufacturer
A repair has been completed and verified, but a permanent diagnostic trouble code (PDTC) remains stored. Technician A says the PDTC can be erased with the scan tool's clear-codes function like any other code. Technician B says disconnecting the battery for several minutes will erase it. Who is right?
Correct answer: D - Neither Technician A nor Technician B
A technician is identifying an unfamiliar transaxle. All of these are characteristics of a dual-clutch transmission (DCT) EXCEPT:
Correct answer: B - A belt or chain running between two variable-width pulleys
A vehicle accelerates poorly from a stop but performs normally at highway speed. Fluid level and condition are correct, line pressure is within specification, and no diagnostic trouble codes are stored. Which condition is MOST likely?
Correct answer: C - A stator one-way clutch that is slipping and not holding
Line pressure is measured at the test port. Pressure is below specification in Drive but within specification in Reverse, Neutral, and Park. This result MOST likely indicates:
Correct answer: A - A leak in a circuit used only in Drive
A front pump seal has leaked again after each of two correct replacements. Any of these could be responsible EXCEPT:
Correct answer: D - A torque converter clutch that will not apply on command
A vehicle equipped with stop/start (idle stop) exhibits a delayed, harsh engagement immediately after each automatic engine restart. Engagements and shifts are normal at all other times. Which component should be inspected FIRST?
Correct answer: B - The auxiliary transmission fluid pump or pressure accumulator
Using a scan tool's bidirectional controls, a technician commands a shift solenoid on and off. The scan tool confirms the command is executing and the solenoid can be heard clicking, but the transmission does not change gears. This result indicates the fault is MOST likely:
Correct answer: A - A hydraulic or mechanical fault inside the transmission unit
A vehicle has harsh shifts in all gears. A pressure control (EPC) solenoid circuit code is stored, and measured line pressure is above specification at idle. Which explanation is MOST consistent with these findings?
Correct answer: D - The control module has defaulted to maximum line pressure
With the engine at full operating temperature, a scan tool displays a transmission fluid temperature of -40 degrees C (-40 degrees F). Which condition MOST likely produced this reading?
Correct answer: C - An open in the fluid temperature sensor signal circuit
