What does code P1750 mean?

Q: What does code P1750 mean?

Secondary Pressure Solenoid Circuit Range Performance. P1750 on BMW vehicles indicates that the transmission control module has detected an out-of-range performance condition in the secondary pressure solenoid circuit, which controls hydraulic pressure for shifting and clutch engagement. The computer monitors the solenoid's electrical current and the resulting pressure response, and it flags this code when the measured behavior falls outside the expected range for the commanded duty cycle.
