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

Incorrect. Please choose another answer.

Technician B is correct because the oil pump assembly could be the diagnostic item and is an OFF-vehicle procedure. Technician A is wrong because the control valve is likely to be the cause in an ON-vehicle procedure, NOT an OFF-vehicle procedure.

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

Incorrect. Please choose another answer.

The only OFF-vehicle repair listed for a vehicle that exhibits a shock when shifting from "N" to "D" range is the FORWARD clutch. All of the other distracters are ON-vehicle repairs.

3 Technician A says you pick the symptom in the on-line service information that closely matches the customer concern. Technician B says the customer will describe their concerns as they are listed in the on-line service information. Who is right?

a. A only

b. B only

c. Both A and B

d. Neither A nor B

Incorrect. Please choose another answer.

You pick the symptom in the on-line service information that closely matches the customer concern. The customer will generally describe their concerns much differently than they are listed in the on-line service information.

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

Incorrect. Please choose another answer.

Checking the flex plate is not part of the preliminary diagnosis process.

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

Incorrect. Please choose another answer.

Both technicians are correct. Tech A is right because many suspension and driveline concerns and noises may appear to be caused by the transmission or transaxle, when they are caused by the suspension. For diagnosis, you put the transmission in neutral and see if the concern changes or goes away. If it goes away, the automatic transmission should be investigated. Tech B is right because you always do the easy and simple inspections first to make sure that you have not overlooked something and you can use the scan tool for further clarification.

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

Incorrect. Please choose another answer.

Oxidation from under or overfilling will cause the fluid to be varnished with a light to dark brown color.

In-Vehicle Transmission/Transaxle Maintenance and Repair

7 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

Incorrect. Please choose another answer.

Both technicians are correct. Technician A is right because the (Diagnostic trouble 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 is right because the park/neutral position (PNP) switch being open or shorted would also set a DTC.

8 Technician A says low line pressure on an electronically controlled line pressure can cause the transmission to slip and operate sluggishly. Technician B says line pressure varies with engine speed. Who is right?

a. A only

b. B only

c. Both A and B

d. Neither A nor B

Incorrect. Please choose another answer.

Technician A is correct because low line pressure can cause the transmission to slip and operate sluggishly. Technician B is wrong because the line pressure should not vary with engine speed. It must remain at a constant level to correctly operate the friction components. It will be lower at idle because of lower RPM as sensed by the TCM or PCM.

9 A line pressure test shows low pressure at idle in all ranges on an electronically controlled automatic transmission. Which of the following can be the cause?

a. Maladjusted TP (throttle position) sensor

b. ATF (automatic transmission fluid) temperature sensor

c. Open in dropping resistor circuit

d. Oil pump pressure regulator

Incorrect. Please choose another answer.

A problem in the oil pump or oil pump pressure regulator will cause low pressure at idle in all gear ranges. Answer option A is wrong because a misadjusted TPS can cause high line pressure at idle not low. B is wrong because a problem with the ATF temperature sensor will cause high line pressure at idle not low. C is wrong because an open in a dropping resistor circuit will cause high line pressure at idle not low pressure.

10 Using the chart below to diagnose a 4-speed automatic transaxle, which of the following is the MOST likely cause of no engine braking in manual second?

a. Forward clutch

b. Third clutch

c. Input Sprag

d. 2-4 Band

Incorrect. Please choose another answer.

The 2-4 band is used for manual braking. The forward clutch is not used for braking and is ON in all forward speeds. The third or direct clutch is not used for braking and is ON for direct drive and reverse.

Off-Vehicle Transmission/Transaxle Repair

11 When removing an engine from a vehicle equipped with an automatic transmission, the torque converter does which of the following?

a. Stays with transmission

b. Stays with engine

c. Must be drained

d. Must be flushed

Incorrect. Please choose another answer.

This is the proper procedure when the transmission is not going to be disassembled. If left on the engine, all of the oil will leak out and make a huge mess.

12 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.

When inspecting the flex plate shown in the photo below, you should check it for all of the following, EXCEPT:

a. Cracks.

b. Elongated bolt holes.

c. Damaged starter ring teeth.

d. Crankshaft pilot bearing

Incorrect. Please choose another answer.

Automatic transmissions do not use a crankshaft pilot bearing.

13 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.
