P275FTransmission Fluid Temperature Sensor D Over Temperature Condition
- Generic OBD-II code · Powertrain
- Can trigger limp mode
- How the car detects it
- P275F is the overheating condition for sensor D: the reading is valid and above the calibrated limit. No manufacturer documents the code, the limit or where sensor D sits. The sensor A equivalent P0218 gives an idea of the logic – Saab's Aisin automatic sets it beyond 170 °C lasting over ten seconds and recommends fresh fluid afterwards, because overheated oil loses its additives. A transmission that reports heat at a fourth measuring point is usually working at its edge: heavy trailer, steep climbs, slipping clutch or converter, or a cooler that cannot keep up. The module typically protects itself with altered shifting or less torque; the code is not an electrical fault, so check fluid and cooling first.
