While discussing valve body assemblies in late-model transmissions: Technician A says that the valve body is no longer needed in some electronically controlled transmissions. Technician B says that an EPC solenoid maintains constant fluid pressure through the valve body regardless of the vehicle’s operating condition. Who is correct?

answer the following questions on automatic transmission diagnositc trouble codes. Complete the following table for the conditions required to run a P0741 DTC. The monitor will run whenever the following DTCs are not present 'ECT (Engine coolant temperature) Transmission range TFT (Transmission fluid temperature): TFT sensor circuit 'ECT sensor circuit Turbine speed sensor circuit Intermediate shaft speed sensor circuit Output speed sensor circuit Shift solenoid valve SL1 circuit Shift solenoid valve SL2 circuit Shift solenoid valve SL3 circuit Shift solenoid valve S4 circuit Shift solenoid valve SR circuit Shift solenoid valve DSL circuit Electronic throttle system

Technician A says that some manual transmissions use 85/90 weight gear oil or synchromesh transmission fluid.Technician B says that some manual transmissions use automatic transmission fluid.Who is correct?

An electronically controlled transmission has erratic shifting: Technician A says that a poor PCM ground will cause this problem. Technician B says that a bad AC generator-to-battery circuit will cause erratic performance of a transmission or transaxle. Who is correct?
