An electromechanical device used to control oil flow to bands and clutches in an automatic transmission to help shift the transmission is the: Group of answer choices torque converter clutch. throttle position sensor. shift solenoid. potentiometer.

shift solenoid.

All the following statements are true except: Group of answer choices In a fully hydraulically controlled transmission, the shift points are controlled by the vehicle's power train control module (PCM). In a fully electronically controlled transmission, the shift points are controlled by the vehicle's power train control module (PCM). In a fully electronically controlled transmission, the shift points are controlled by the vehicle's transmission control module (TCM). On a hydraulically controlled transmission, the computer can react to the increased load only after the transmission shifts.

In a fully hydraulically controlled transmission, the shift points are controlled by the vehicle's power train control module (PCM).

All of the following statements are true except: Group of answer choices The PCM or the TCM is the brain in the system. The PCM monitors the TPS sensor along with the VSS to determine a driver's driving pattern. Slippery conditions require a gear ratio that enhances traction and the stability of motion of the vehicle. Increasing the amount of torque being transmitted to the transmission reduces transmission wear.

Increasing the amount of torque being transmitted to the transmission reduces transmission wear.

All of the following statements are true with respect to the vehicle speed sensor (VSS) except: Group of answer choices It is responsible for sending the vehicle speed information to the vehicle speedometer. It is sometimes called an output shaft speed sensor. It is often also responsible for sending the vehicle speed information to the vehicle speedometer. It can never replace a governor in a computerized transmission.

It can never replace a governor in a computerized transmission.

.All the following statements describing the VSS are true except: Group of answer choices The types of VSS are magnetic pickup and reed switch. An input shaft speed sensor is similar to a VSS and relays its signal to the PCM. It relays vehicle speed information to the speedometer. It is primarily used to determine functionality of emissions related components.

It is primarily used to determine functionality of emissions related components.
