P0711 Transmission fluid temperature sensor A range/performance
What P0711 means
The transmission control unit sees fluid temperature readings that do not make sense, for example not rising as the car warms up. Shift quality and torque converter lock-up depend on this value.
P0711 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Parts and labour at an independent workshop in Europe. Main dealers charge more; the cause decides the bill, not the code.
Symptoms
- Harsh or delayed shifts
- Torque converter not locking up
- Check engine or transmission warning on
- Possible limp mode
Common causes
- Faulty transmission fluid temperature sensor
- Damaged wiring harness inside or outside the gearbox
- Low or degraded transmission fluid
- Genuine overheating from towing or a blocked cooler
Can I keep driving with P0711?
You can drive carefully, but have it checked within one to two weeks. Avoid towing and heavy loads.
What to check first
- Check transmission fluid level and condition
- Compare fluid temperature with coolant temperature in live data after a cold start
- Inspect the gearbox connector and harness
- Replace the sensor or internal harness
