P0750 Shift solenoid A
What P0750 means
The transmission control unit has found an electrical or performance fault with shift solenoid A, which directs fluid to apply clutches for certain gears. The gearbox may skip gears, shift harshly or stay in one gear.
P0750 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.
