P2764 Torque converter clutch pressure control solenoid control circuit low

TCC pressure solenoid circuit low

P2764 in short

P2764 means the computer saw a low voltage on the circuit for the solenoid that controls torque converter clutch pressure, often from a short to ground or a failed solenoid. Expect shudder, lurching or warning lights. Wiring, the solenoid or valve body and the torque converter are common causes. Have it inspected promptly.

The torque converter clutch locks the engine to the transmission at cruising speed. A solenoid controls the pressure that applies it. P2764 sets when the computer sees the voltage on that solenoid's control circuit is lower than expected, typically a short to ground or an open solenoid.

Owners most often report P2764 on Subaru CVTs, where dealers replaced the solenoid or valve body, and on Chrysler 62TE minivans. Chrysler's 62TE guidance says to check the solenoid and, if it is good, suspect the torque converter.

Most likely causes

  1. Wiring short to ground or connector fault

    Common general cause
    Why it ranks here
    A low-circuit code points to wiring first, and a Chrysler dealer found the feed to the valve body shorted to ground.
    What would change this
    Rises if the circuit has low resistance to ground.

  2. Faulty TCC pressure solenoid or valve body

    Common general cause
    Why it ranks here
    The solenoid and valve body are listed causes, and Subaru dealers replaced them for P2764.
    What would change this
    Rises if the solenoid resistance is out of spec.

  3. Torque converter failure (Chrysler 62TE)

    Supported by vehicle data
    Why it ranks here
    Chrysler says if a 62TE is jerking or slipping with P2764 and the solenoid tests good, the torque converter has failed.
    What would change this
    Rises on a 62TE vehicle that jerks or slips with a good solenoid.

  4. Low or dirty fluid or leaks

    Possible — needs testing
    Why it ranks here
    Fluid and leaks are listed, though they less often cause a circuit-low code.
    What would change this
    Rises if the fluid is low.

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

    • IfP0740 or other converter clutch codes are also stored

      It meansCheck the solenoid and converter.

      Go to step 2

    • IfP2764 alone

      It meansHave the circuit tested.

      Go to step 3

  2. Check for a P2764 bulletin for your VIN at a dealer or on the NHTSA site.

    Low risk

  3. Have a shop check the solenoid circuit for a short to ground and measure the solenoid.

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

    Warning:Shop test. It needs the maker's wiring diagram.

Symptoms

  • Check engine light, often with other dash lights
  • Shudder at cruising speed
  • AT oil temperature light flashing (Subaru) Gets more serious: stop and have it checked.
  • Lurching or will not drive 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. Ask a dealer whether your VIN has an open P2764 bulletin or software update.

On your vehicle

Dodge

  • 2011–2020

    Supported by vehicle data

    Chrysler 9004206 says P2764 with jerking or slipping on the 62TE points to the TCC solenoid or the torque converter (also Chrysler 200, Town & Country and Ram ProMaster). The bulletin is on NHTSA, but whether it is still current is not verified, so it is labelled vehicle data rather than confirmed.

  • 9004206Status unverified

    Remanufactured 62TE transmission assembly

    2011–2020journey, grand-caravan, avenger · issued · NHTSA 10193951

    If jerking or slipping with P0740 or P2764, check the TCC solenoid; if good, replace the torque converter. Also covers the Chrysler 200 and Town & Country and Ram ProMaster. 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.

Subaru

  • 2011–2012 · Outback

    Supported by vehicle data

    Owners report P2764 with a flashing AT oil temp light and solenoid or valve body replacement, per complaints to NHTSA. These are owner reports, not a bulletin.

  • P0740Torque converter clutch control circuit fault

    Shares causes Supported by vehicle data

    Chrysler treats P0740 and P2764 together on the 62TE.

  • P0700Transmission module requests the check engine light

    Primary / secondary Possible — needs testing

    Likely primary: P2764. A basic reader may show only P0700; P2764 can be the module's own code, as in a 2012 Outback complaint.
