P0711 means the fluid temperature signal is electrically valid but implausible. Manufacturers check three things: the fluid does not warm up as expected (GM 2025 still below 15 °C after the calibrated warm-up time, Saab's AF40 below 20 °C after 10 minutes of driving), the value is stuck (Ford: within ±2 °F for about 2.5 minutes below 70 or above 225 °F), or it jumps unrealistically. GM's 6T70 compares it with the module's internal temperature. The MIL rating varies: GM's newer modules after two trips, Saab AF40 none, Ford none; a 2013 Ram 6.7 bulletin moved P0711–P0714 from one to two trips. A substitute value then limits adaption and converter clutch control.
Medium severity. Can I keep driving?Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
Symptoms
- Harsh or late shifts
- Torque converter clutch applies late or not at all
- Check engine or transmission lamp depending on manufacturer
- Implausible fluid temperature in the scan tool
Most likely causes
- Fluid temperature sensor drifting or stuck
- High contact resistance in connector or harness (oil, corrosion)
- Very cold weather or short trips (fluid does not reach warm-up threshold)
- Outdated module software
- Fluid cooler thermostat faulty
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
What each character of P0711 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 7: Transmission
- 11: Specific fault in that system
Frequently asked questions
Can I keep driving with code P0711?
Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
What causes code P0711?
The most common causes are: fluid temperature sensor drifting or stuck; high contact resistance in connector or harness (oil, corrosion); very cold weather or short trips (fluid does not reach warm-up threshold).
