Exam 12: In-Vehicle Transmission Repairs

Which of the following is heavily loaded during a stall test?

High-quality aftermarket and factory scan tools can show live data. Which of the following items can be seen from the data list?

If you are expecting a reading of 120 pounds per square inch (psi) (827 kilopascals [kPa]) while you are pressure testing an automatic transmission and you select a gauge that reads up to 400 psi (2,758 kPa), you may not get an accurate reading.

The stall test to check torque converter operation is not recommended by all manufacturers to diagnosis a transmission problem.

Technician A says that if a vehicle does not present any concerns on a diagnostic test drive, the vehicle can be returned to the customer. Technician B says that during a diagnostic test drive, the vehicle must be operated under the exact same conditions of the complaint. Who is correct?

When test driving a vehicle with a scan tool, what can be done to avoid an accident because of distracted driving?

Which of the following can cause higher than normal line pressure in an automatic transmission?

Technician A says that if a vehicle does not present any concerns on a diagnostic test drive, the vehicle can be returned to the customer. Technician B says that during a diagnostic test drive, the vehicle must be operated under the exact same conditions of the complaint. Who is correct?

The diagnostic procedures encountered during the repair of an automatic transmissions electrical system will often require the use of a digital multimeter (DMM) or digital volt ohm meter (DVOM) to aid in the diagnosis of wiring, switches, solenoids, sensors, and actuators.

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

Technician A says you can clean a transmission cooler and lines using the shop's parts cleaning tank. Technician B says you can clean a transmission cooler and lines with an aerosol flushing kit. Who is correct?

When using a scan tool to monitor electronic components inside and outside of the transmission during a road test, which of the following precautions has to be taken?

When diagnosing an automatic transmission problem, it is important to first verify the customer concern by taking the vehicle on a road test, if possible.

If a vehicle has a broken powertrain mount, what symptoms might a customer us to describe their concern?

Technician A says when diagnosing a torque converter clutch (TCC) solenoid problem, use a multimeter to check for ground and power first. 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?

Technician A says that the cooler and cooler lines should be flushed as part of a transmission rebuild. Technician B says that if the cooler is not flushed oil returning from the cooler can carry debris into the torque converter, and cause damage to it. Who is correct?

Which of the following can cause an electronic transmission to operate incorrectly?

What tools are commonly used when performing an in-vehicle diagnosis of an automatic transmission?

What can a leaking automatic transmission fluid cooler cause?

Which of the following can cause higher than normal line pressure in an automatic transmission?
