P2764 — Torque Converter Clutch Pressure Control Solenoid Control Circuit Low

OBD2 code P2764 flags a problem with the automatic transmission control (torque converter clutch pressure control solenoid control circuit low). Short, gentle driving to a shop is usually possible. Common culprits: faulty transmission speed sensor, internal mechanical wear (clutches, torque converter), valve body wear.

powertrain (engine/transmission)

Is it safe to drive?

Drive with caution Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How to diagnose with an OBD scanner

  1. Read the code and freeze frame Connect an OBD2 scanner, confirm P2764 is stored, and save the freeze frame data — it shows engine conditions when the fault was detected.
  2. Check for companion codes and TSBs Related codes often reveal the real root cause. Also check manufacturer technical service bulletins (TSB) for your make and model — many P0xxx issues have factory fixes or software updates. Search by VIN on the manufacturer site or nhtsa.gov.
  3. Inspect wiring and connectors Visually inspect the wiring harness and connectors related to the automatic transmission control for damage, corrosion, chafing or poor contact.
  4. Subsystem check Check for supply voltage at the torque converter clutch pressure control solenoid control connector first; then measure resistance from the signal wire to ground — near-zero ohms confirms a short to ground in the harness.
  5. Subsystem check Check transmission fluid level and condition — dark, burnt fluid points to internal wear.
  6. Subsystem check Read transmission-specific codes and live data (solenoid states, input/output speed) with a capable scanner.
  7. Verify the repair Clear the code, complete a full drive cycle including the conditions from the freeze frame, and confirm P2764 does not return.

Approximate repair cost

Repair cost depends on which component actually failed. Typical scenarios for P2764 (parts and labor, USD, independent shop rates): Replace a shift solenoid: $300–$800; Transmission fluid service: $150–$350; Valve body repair or replacement: $700–$1,500; Transmission rebuild or replacement: $2,500–$5,500. Overall, fixing P2764 usually costs between $150 and $5,500. An accurate diagnosis before buying parts saves money — the most expensive scenario is rarely the first one to check.

Common questions

What does OBD2 code P2764 mean?

OBD2 code P2764 flags a problem with the automatic transmission control (torque converter clutch pressure control solenoid control circuit low). Short, gentle driving to a shop is usually possible. Common culprits: faulty transmission speed sensor, internal mechanical wear (clutches, torque converter), valve body wear.

Will P2764 clear itself?

Sometimes P2764 clears after a few drive cycles if the fault was intermittent — for example a loose connector or a tank of bad fuel. The underlying cause usually remains, so the code tends to return. Clear it once; if it comes back, diagnose rather than erase it repeatedly.

How much does it cost to fix P2764?

Replace a shift solenoid — $300–$800; Transmission fluid service — $150–$350; Valve body repair or replacement — $700–$1,500; Transmission rebuild or replacement — $2,500–$5,500. Exact cost depends on the root cause, your vehicle and local labor rates — a proper diagnosis is the cheapest first step.

Is it safe to drive with P2764?

Drive only if the transmission still shifts predictably, and avoid highway speeds. Driving with slipping or limp mode accelerates internal wear — every kilometre can add to the final repair bill.

How do I diagnose P2764 myself?

Start with a scan: confirm P2764, save the freeze frame and note any companion codes. Then inspect the wiring and connectors related to the torque converter clutch pressure control solenoid control, and verify the suspect component against live data before buying parts.

What does P2764 mean?

Seeing P2764 on your scanner? The control unit has caught the automatic transmission control operating outside its calibrated window. The formal description is “Torque Converter Clutch Pressure Control Solenoid Control Circuit Low”, and the code is grouped under powertrain (engine/transmission) faults.

“Circuit low” means the voltage on the torque converter clutch pressure control solenoid control circuit stays below the expected minimum — close to ground. The usual physical reasons are a short to ground, a chafed wire touching metal, a missing supply voltage, or a failed component dragging the signal down.

This code does not appear from a single bad reading: the module must see the fault condition repeat under defined operating conditions before it turns on the warning light. The freeze frame captured with P2764 — engine load, rpm, temperature, speed — tells you exactly when the problem occurs, so reproduce those conditions when testing.

What causes P2764?

  • signal wire shorted to ground (chafed insulation)
  • failed torque converter clutch pressure control solenoid control pulling the signal low
  • missing supply voltage to the torque converter clutch pressure control solenoid control
  • internal mechanical wear (clutches, torque converter)
  • wiring or connector faults in the valve body harness
  • valve body wear
  • failed shift or pressure control solenoid
  • faulty transmission speed sensor

Common symptoms of P2764

  • Check Engine or transmission warning light on
  • shuddering at highway speed
  • harsh or delayed shifting
  • no movement in severe cases
  • transmission stuck in one gear (limp mode)
  • slipping between gears
