P0752: Shift Solenoid A Stuck On

Severity: Medium Avoid towing, steep loads, and prolonged driving until diagnosed. Stop and arrange recovery if the transmission slips, loses drive, overheats, or bangs into gear; driving through slip can cause further damage.

What does P0752 mean?

Shift solenoid A appears to remain on when it should switch off. The resulting fluid-routing error can leave the transmission in an unintended gear or cause slip and overheating.

Generic OBD-II definition: Shift Solenoid A Stuck On. Confirm applicability in your vehicle service information.

Common causes

  • Mechanically stuck solenoid A
  • Valve-body contamination or wear
  • Wiring keeping the circuit energized

Symptoms

  • Harsh, missing, or incorrect shifts
  • Limp mode
  • Possible slipping or transmission overheating

Diagnostic focus

Do not equate solenoid A with first gear on every transmission. The same solenoid may contribute to several gears, depending on the hydraulic design.

Can I keep driving with P0752?

Severity: Medium Avoid towing, steep loads, and prolonged driving until diagnosed. Stop and arrange recovery if the transmission slips, loses drive, overheats, or bangs into gear; driving through slip can cause further damage.

If the check engine light is flashing or the car runs badly, stop driving and have it checked.

Typical fixes

  • Compare commanded A state with transmission response
  • Inspect for a control-wire short
  • Have the solenoid and related hydraulic valve checked
