P0752 Shift solenoid A stuck on

Shift solenoid A stuck on

P0752 in short

P0752 means the transmission computer thinks shift solenoid A is stuck on, so the gear it controls stays applied. Expect harsh shifts, a stuck gear or limp mode. Low or dirty fluid, the solenoid or valve body, and wiring are common causes. Have it inspected soon, and do not keep driving if the car loses drive.

Shift solenoids are electrically switched valves that send fluid to the clutches for each gear. P0752 sets when the computer commands solenoid A off but the gear ratio or pressure still behaves as if it were on, so it decides the solenoid or its valve is stuck on.

A stuck solenoid is often mechanical: dirty fluid, debris or a worn valve body can hold the valve open. Wiring faults can also make a solenoid look stuck. Which gears solenoid A affects depends on the transmission.

Dealers have fixed P0752 by replacing a solenoid, the valve body or the transmission computer, and Ford and GM bulletins list it with harsh or delayed shifts on some transmissions.

Most likely causes

  1. Shift solenoid A or valve body sticking

    Common general cause
    Why it ranks here
    Code references list the solenoid and valve body, and a dealer replaced the valve body for P0752 on a 2026 Crosstrek because the solenoid was not sold separately.
    What would change this
    Rises if the solenoid does not respond when commanded or debris is found in the valve body.

  2. Low, dirty or wrong transmission fluid or a clogged filter

    Common general cause
    Why it ranks here
    Dirty fluid and a clogged filter are listed causes and can make a solenoid valve stick.
    What would change this
    Rises if the fluid is low, dark, burnt-smelling or full of debris.

  3. Solenoid wiring or connector fault

    Common general cause
    Why it ranks here
    Wiring and connectors are listed causes for solenoid codes.
    What would change this
    Rises if the connector is damaged or the circuit fails a shop check.

  4. Transmission computer fault or outdated software (some GM and Ford models)

    Supported by vehicle data
    Why it ranks here
    A GMC dealer replaced the transmission computer for P0752 on a 2008 Acadia, a Saturn Outlook dealer blamed the module, and Ford covers P0752 on the 10R80 with a bulletin.
    What would change this
    Rises on a GM Lambda crossover (Acadia, Outlook) or a 10R80 Ford with other module codes such as P0700.
    How to test the transmission control module (tcm)

What to test first

Start at step 1. Each result tells you what it means and where to go next.

  1. Read codes from the engine and transmission modules with a scan tool that supports both, before anything is cleared.

    Low riskTool: scan tool that reads the transmission module

    • IfOther solenoid or module codes are stored with P0752

      It meansSeveral codes together can point to wiring, power or the computer.

      Go to step 2

    • IfP0752 alone

      It meansLook for a bulletin, then check the fluid.

      Go to step 2

  2. Check for a P0752 bulletin for your VIN at a dealer or on the NHTSA site.

    Low risk

  3. Have a shop check the fluid, then command solenoid A with a scan tool and test its circuit.

    Best left to a shopTool: scan tool with transmission data and output controls

    Warning:Shop test. It needs the maker's wiring diagram, pressure specs and test procedure.

Symptoms

  • Check engine light
  • Harsh or delayed shifts
  • Stuck in one gear, or will not shift out of first
  • Sudden loss of acceleration or limp-home mode Gets more serious: stop and have it checked.

How to fix

  1. Do not clear the code before the transmission module has been read; the stored data helps the shop.

  2. Check the transmission fluid level and condition if your transmission has a dipstick or the owner's manual describes a check, and look for leaks under the car.

  3. Ask a dealer whether your VIN has an open P0752 bulletin or software update.

Parts and cost context

  • Transmission control module (TCM):Some dealers replaced the transmission computer for P0752, but rule out fluid, wiring and the solenoid or valve body first unless a bulletin points to the module.

On your vehicle

Ford

  • 2017–2020 · F-150

    Supported by vehicle data

    Ford TSB 23-2123 covers harsh or delayed shifts with P0752 on the 10R80 10-speed (also 2018–2021 Expedition and Mustang, 2019–2023 Ranger). The bulletin is on NHTSA, but whether it is still current is not verified, so it is labelled vehicle data rather than confirmed.

  • TSB 23-2123Status unverified

    10R80 harsh engagement, harsh or delayed shift

    2017–2023f-150, expedition, mustang, ranger · issued · NHTSA 10234596

    May have the MIL with P0751, P0752 and other shift codes. Also covers the Lincoln Navigator. Only the NHTSA flat-file summary was read, not the bulletin itself.

    We couldn't confirm whether this bulletin is still current, so it doesn't count as confirmation.

GMC

  • 2008 · Acadia

    Supported by vehicle data

    A GMC dealer replaced the transmission computer and a shift solenoid for P0752, per an owner complaint to NHTSA. This is one owner report, not a bulletin.

Saturn

  • 2007 · Outlook

    Supported by vehicle data

    A dealer read P0752 with P0989, P0877 and P0700 and described transmission computer issues, per an owner complaint to NHTSA. This is one owner report, not a bulletin.

Mazda

  • 2002 · MPV

    Supported by vehicle data

    A Mazda dealer diagnosed total transmission failure with P0752, per an owner complaint to NHTSA. This is one owner report, not a bulletin.

  • P0751Shift solenoid A performance or stuck off

    Same system Possible — needs testing

    P0751 is the stuck-off or performance code for the same solenoid; a 2021 Escape owner reported both, and Ford and GM bulletins list them together.

  • P0700Transmission module requests the check engine light

    Primary / secondary Possible — needs testing

    Likely primary: P0752. On cars with a separate transmission module a basic reader may show only P0700. P0752 can be the module's own code, as on the 2026 Crosstrek complaint.

  • P0750Shift solenoid A circuit malfunction

    Same system Possible — needs testing

    P0750 is the general circuit code for the same solenoid A.
