A vehicle comes into the shop with soft shifts. You measure line pressure and find that the line pressure is low. You check the voltage coming out of the transmission pressure sensor and find that it is 5 volts. Tech A states that the vehicle has a problem with the line pressure sensor. Tech B states that the vehicle needs a new pump or line pressure solenoid. Who is correct?

Question

Tech B is correct because low line pressure with a 5-volt reading from the pressure sensor indicates that the sensor is likely functioning correctly (as 5 volts typically represents maximum pressure), suggesting an issue with the pump or line pressure solenoid.
