P2760 — Torque Converter Clutch Pressure Control Solenoid Control Circuit Intermittent

Manufacturer-specificPowertrain (engine & transmission)

P2760 means the Powertrain Control Module (PCM) or Transmission Control Module (TCM) has detected an intermittent electrical fault in the circuit that drives the torque‑converter‑clutch (TCC) pressure control solenoid. The TCC solenoid is responsible for engaging the torque‑converter lock‑up clutch to improve efficiency; when its control circuit is intermittent, the converter may not lock up properly, causing slip, harsh shifts, or reduced fuel economy. The code signals a problem in the wiring or the solenoid itself rather than a definite component failure.

Symptoms

What causes it — most likely first

1. Defective TCC Pressure Control Solenoid

The solenoid itself can develop an internal open or short, producing intermittent electrical signals.

2. Wiring or Connector Damage

Frayed, chafed, or corroded wires, as well as loose or dirty connectors in the TCC circuit, can cause intermittent shorts or opens.

3. Low or Contaminated Transmission Fluid

Insufficient or dirty fluid can prevent the solenoid from building proper pressure, leading to intermittent operation.

4. Faulty Pressure Switch/Sensor

The switch that monitors TCC pressure can send erratic data, potentially triggering the code.

5. PCM/TCM Malfunction

A failed control module is possible but usually only after all other electrical components have been verified good.

How it's diagnosed

  1. Connect an OBD‑II scanner to confirm P2760 and note any related transmission codes.
  2. Visually inspect the TCC solenoid wiring harness and connector for damage, corrosion, or looseness.
  3. Measure the solenoid’s resistance with a multimeter and compare to manufacturer specs; check for opens or shorts to ground.
  4. Verify proper voltage and ground at the solenoid connector while the engine is running (if safe).
  5. Check transmission fluid level and condition; top up or replace fluid if necessary.
  6. If wiring and fluid are okay, replace the TCC pressure control solenoid, clear the code, and road‑test the vehicle.
  7. If the code persists after solenoid replacement, perform a comprehensive TCM/PCM test and consider module reprogramming or replacement.

Frequently asked

Is P2760 a serious code?

It indicates the torque converter clutch isn’t locking up reliably, which can reduce fuel economy and cause the transmission to run hotter. It should be diagnosed promptly to avoid potential transmission damage.

I was told to replace the PCM for P2760. Is that really necessary?

In most cases the PCM is not at fault. The problem is usually the solenoid, its wiring, or the transmission fluid. Replacing the computer should only be considered after those items have been ruled out.

Can I keep driving with P2760 set?

You can drive short distances, but prolonged operation with the torque converter not locking may lead to overheating and increased wear. It’s advisable to have the issue inspected soon.

What does 'intermittent' mean for this code?

The fault does not occur continuously; it may only appear under certain conditions (e.g., specific temperatures or load). This can make the problem harder to duplicate during diagnostics.
