P275F code meaning
Transmission Fluid Temperature Sensor D Over Temperature Condition
What P275F means
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.

Symptoms of P275F
- Overheating warning or message
- Changed shifting or reduced power
- Dark or burnt-smelling fluid
Common causes of P275F
- Most likelyHeavy trailer or long steep climbs
- PossibleSlipping clutch or torque converter
- PossibleCooler blocked or not keeping up
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P275F means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 7 | Area: transmission. |
| 5F | The exact fault in that area. |
What to do next
- Note P275F and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P275F
What does P275F mean?
P275F means "Transmission Fluid Temperature Sensor D Over Temperature Condition". P275F is the overheating condition for sensor D: the reading is valid and above the calibrated limit. It is a generic code, so it means the same on every make.
Is it safe to drive with P275F?
Drive gently and only to a workshop. With P275F the car can go into limp mode (reduced power) to protect itself.
Will P275F fail an emissions test?
P275F is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P275F to fix?
Difficulty: medium. A typical repair takes 0.5 to 5 hours of work. This is a job for a workshop.
Will P275F clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
