P0750: Shift Solenoid A Malfunction
29 vehicles · 9 makes · $100-$5,000 repair
Most Reported On
P0750 is an OBD-II diagnostic trouble code meaning “Shift Solenoid A Malfunction.” This code indicates the transmission control system detected a malfunction in shift solenoid 'A', one of the electrically operated valves that direct hydraulic fluid to engage gears. The computer commands these solenoids to control upshifts and downshifts, and it monitors their circuits and the resulting gear changes. When solenoid A doesn't respond electrically as expected — or the resulting shift doesn't happen correctly — this code is set. You may notice harsh, delayed, or missing shifts, or the transmission may enter a fail-safe (limp) mode. This code is most commonly reported on 1996-2003 Ford Windstar, 1998-2011 Ford Crown Victoria, and 1996-2008 Dodge Ram 1500, plus 26 other vehicles, with repair costs ranging from $100 to $5,000.
