Exam 12: In-Vehicle Transmission Repairs

A technician who does not have the ability to diagnose a transmission failure may incorrectly recommend transmission replacement or overhaul.

Typically, a technical service bulletin (TSB) contains which of the following information?

Having access to what would allow the technician to test drive the vehicle in the repair shop?

To check the pump operation, what test should the technician conduct?

Which of the following is not an in-vehicle transmission repair?

Because hybrid vehicles are showing up in non-dealership repair facilities in greater numbers every day, it is important to understand their operating principles.

Which of the following is used when performing an in-vehicle diagnosis of a transmission?

Technician A says that a hydraulic pressure test can be done with the transmission installed in the vehicle. Technician B says that a scan tool DTC retrieval may indicate a possible area of concern. Who is correct?

Technician A says when diagnosing a torque converter clutch (TCC) solenoid problem, you should use a scan tool to identify any diagnostic trouble codes (DTCs) the powertrain control module (PCM) has identified related to the TCC circuit. Technician B says when checking the resistance of the TCC solenoid through the connector and the resistance is out of specifications, the problem could be the solenoid or wires to the solenoid inside the transmission pan. Who is correct?

When diagnosing problems in the transmission:

During automatic transmission testing on a hoist, what is the maximum speed the vehicle should be operated?

Technician A says that a hydraulic pressure test can be done with the transmission installed in the vehicle. Technician B says that a scan tool DTC retrieval may indicate a possible area of concern. Who is correct?

Which of the following is a good first step in diagnosis of any transmission concern?

When you are removing a transmission, you should wear eye protection to prevent which of the following from getting into your eyes?

To properly diagnose a problem with an automatic transmission, you need to do a thorough inspection of the transmission and perform several diagnostic tests.

Hydraulic mounts use _______ fluid that is squeezed back and forth between two chambers, similar to the design of a shock absorber.

The automotive technician should not perform a stall test if there is an engine problem, such as worn engine bearings, broken power train mounts, or an engine overheating condition.

In order to prevent severe transmission damage, what is the maximum length of time a stall test should be performed?

Two technicians are discussing electronically controlled automatic transmissions. Technician A says a digital multimeter (DMM) or digital volt ohm meter (DVOM) is used to aid in the diagnosis of wiring, switches, solenoids, sensors, and actuators. Technician B says you should follow the diagnostic step by step until you have completed the diagnostic procedure and found the cause of the diagnostic trouble code (DTC). Who is correct?

Many automotive manufactures do not recommend performing a ______ test to automatic transmissions.
