P0752: Shift Solenoid A Stuck On — what it means, the affected system and what to check before replacing parts.

Meaning, symptoms, causes and checks

Shift Solenoid A Stuck On. Basic catalogue definition; diagnostic details have not yet been reviewed.

Affected system: Powertrain

Symptoms

  • A transmission warning or delayed or harsh gear changes may occur; symptoms vary by vehicle.
  • P0752 describes shift solenoid A stuck on; it is not proof that the solenoid itself must be replaced.

Possible causes

  • Contaminated/low transmission fluid, a sticking solenoid or a valve-body restriction may affect shifting.
  • A harness or electrical connector fault should be ruled out before replacing transmission components.

What to check

  • Confirm P0752, associated codes and freeze-frame information.
  • Check fluid level and condition using the gearbox-specific procedure; inspect accessible wiring and connectors.
  • Where supported, compare commanded action of solenoid A with observed behavior before any replacement.
