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.
The solenoid itself can develop an internal open or short, producing intermittent electrical signals.
Frayed, chafed, or corroded wires, as well as loose or dirty connectors in the TCC circuit, can cause intermittent shorts or opens.
Insufficient or dirty fluid can prevent the solenoid from building proper pressure, leading to intermittent operation.
The switch that monitors TCC pressure can send erratic data, potentially triggering the code.
A failed control module is possible but usually only after all other electrical components have been verified good.
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.
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.
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.
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.
