ASE Practice Test A2 - Automatic Transmission - General Transmission/Transaxle Diagnosis

Oct 2, 2026

Uploaded by Mia

Practice test covering automatic transmission diagnosis and repair decision-making, focused on electronically controlled systems. Topics include interpreting symptom charts, determining which tests require off-vehicle service, and selecting the correct diagnostic logic for line pressure faults, shift shock, and EXCEPT-style questions. Also covers fluid inspection color causes, identifying coolant-related contamination, stall test purpose and ordering, and maintenance checks for manual valve control cables and park/neutral switch circuits.

ASE Practice Test A2 Automatic Transmission General Transmission/Transaxle Diagnosis 1) You are using a diagnostic symptom chart to diagnose an electronically controlled 5-speed automatic RWD (rear wheel drive) transmission with a strange noise in drive. Technician A says the control valve could be the cause and is an OFF-vehicle procedure. Technician B says the oil pump assembly could be the cause and is an OFF-vehicle procedure. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B 2) On an electronically controlled 4-speed automatic transaxle, you experience a “shock”when shifting from “N” to “D”. Which of the following will require an OFF-vehicle repair? a. Line pressure test b. A/T fluid temperature sensor c. Control valve assembly d. Forward clutch 3) Technician A says you pick the symptom in the online service information that closely matches the customer concern. Technician B says the customer will describe their concerns as they are listed in the online service information. Who is correct? a. A only b. B only c. Both A and B d. Neither A nor B 4) This question has the word EXCEPT. For this question, look for the choice that could NOT fit the described situation. Read the entire question carefully before choosing your answer. Preliminary diagnosis on an electronically controlled automatic transmission/transaxle consists of all the following tests EXCEPT: a. Line pressure test b. Fluid check c. Stall test d. Flex plate check 5) Technician A says engine, suspension and driveline problems may appear to be caused by the transmission or transaxle. Technician B says you start with the simple inspections first to ensure that you have not overlooked something and you can use the scan tool for further clarification. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B 6) You are checking fluid color on an automatic transmission/transaxle. Which of the following will cause the fluid to be varnished with a light to dark brown color? a. Oxidation from overfilling b. Water contamination c. Engine coolant contamination d. Wear from friction material 7) If the fluid inspection shows a pinkish color and indicates water contamination, which coolant system component is the possible cause? a. Dipstick b. Cooler c. Water pump d. Heater core 8) Technician A says the stall test is performed to see if the torque converter and internal holding components operate properly. Technician B says the stall test is conducted before the line pressure test. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B In-Vehicle Transmission/Transaxle Maintenance and Repair 9) A technician is checking the automatic transaxle manual valve control cable after an adjustment. Technician A says to make sure the transaxle is locked properly when theselector lever is placed in the P position. Technician B says to make sure that the starter operates only when placed in the N position. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B 10) A technician moves the gear selector lever from the PARK position to the MANUAL LOW position and cannot hear the detent and the pointer indicating the gear position is misaligned. Which of the following could be the cause? a. Replace control cable b. Adjust control cable c. Adjust PNP (park neutral position) switch d. Replace PNP (park neutral position) switch 11) DTC (Diagnostic trouble code) P0705 PNP (park/neutral position) switch circuit is being diagnosed. Technician A says this code sets when the TCM (Transmission Control Module) or PCM (Powertrain control module) does not receive the correct voltage signal from the park/neutral position (PNP) switch. Technician B says the park/neutral position (PNP) switch circuit could be open or shorted. Who is right? a. A only b. B only c. Both A and B d. Neither A nor B 12) Technician A says low line pressure o

FAQs

In an electronically controlled 5-speed automatic RWD transmission, which parts could cause strange noise during drive, and what off-vehicle procedure applies?

The question tests whether the control valve or the oil pump assembly is responsible and whether each has an OFF-vehicle procedure. Select the option that matches the correct technician statement.

For an electronically controlled 4-speed automatic transaxle with a “shock” shifting from N to D, which item requires an OFF-vehicle repair?

The test evaluates which listed component or procedure can only be handled off-vehicle. Choose the option that aligns with the required repair location.

What fluid color change indicates water contamination, and which coolant component could be the cause?

A pinkish color indicating water contamination points to a possible coolant system component cause. The question then asks which component is the likely source, such as the cooler or another listed item.
