P0753 Shift Solenoid A Electrical
A shift solenoid is an electrically switched valve in the valve body. Manufacturers use these codes differently: Ford reports an open circuit with the base code and shorts separately, newer GM units have separate low/high codes, and the letter is not tied to a valve number (Saab's 9-5: A = valve S2). P0753 is the collective electrical code for solenoid A. GM's older engine-controlled 4-speeds check 0/12 V feedback and flag an open or short to ground at more than 43 of 50 failed counts; Subaru compares the driver transistor voltage with the command for 30 ms, lights the MIL after two trips and holds third gear; Saab's Aisin boxes measure current; Hyundai's 8-speed uses it for the underdrive clutch valve. Ford and newer GM do not use P0753.
Likely causes
Symptoms
- Check engine or transmission warning lamp
- Limp mode in a fixed gear, no upshifts
- Harsh shifts from maximum line pressure
Repair estimate
Typical range across vehicles; the real cost depends on what the testing finds.
