A-2 Automatic Transmission Certification Practice Test

1.   Technician A says a TR sensor (Transmission Range Sensor) can be tested using an ohmmeter. Technician B says an improperly adjusted neutral safety switch can prevent a vehicle from starting. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

6.   Two technicians are discussing shift feel. Technician A says a problem with the accumulator will create hard shifting. Technician B says a restricting orifice/check ball restricts the amount of fluid flow providing a smoother shift feel. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

2.   There is a whining noise coming from the front of the transmission that increases with engine speed. This noise is present in all gears including park and neutral. The most likely cause of this is the:

A Extension housing bushing

B Transmission oil pump

C Output shaft

D Torque converter

7.   Technician A says that a shift solenoid is a hydraulically controlled device used by the transmission for shift control. Technician B says the wires in the bus system are twisted to prevent RFI (Radio Frequency Interference). Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

3.   All of the following valves are found in transmission valve bodies except

A Poppet valves.

B Four-way valves.

C Spool valves.

D Check ball valves.

8.   Technician A says that relays are devices that use low current to control high current. Technician B says resisters are used to limit current flow in devices. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

4.   Technician Technician A says the ECT is for the engine and has nothing to do with transmission shift control. Technician B says the MAF sensor provides information about engine load to the TCM (transmission control module) and is important for TCM shift control. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

9.   Technician A says that the VSS (vehicle speed sensor) uses the rotation of the input shaft of an automatic transmission. Technician B says that the parking pawl engages the input shaft to lock an automatic transmission. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

5.   Technician A says light brown transmission fluid is caused by heat and oxidation. Technician B says that dirty screen type filters must be discarded and replaced.Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B

10.   Technician A says that a TP (throttle position) sensor is actually a potentiometer. Technician B says that as the throttle plate moves the resistance in the TP sensor changes. Who is correct?

A Technician A

B Technician B

C Both A and B

D Neither Technician A or B
