Transmission Fluid Temperature Sensor Range/Performance
The P0711 code means the vehicle's onboard diagnostic system has detected: Transmission Fluid Temperature Sensor Range/Performance. This is a moderate severity code.
- Keep driving?
- Short distances only
- DIY difficulty
- moderate
- Estimated cost
- $80 - $300 (parts and labor)
Read and clear transmission codes. Many trans codes are caused by low or burnt fluid -- check level and color before assuming the worst.
Basic scanners only read engine codes. This reads transmission, ABS, and airbag too.

Common Symptoms
- Check Engine Light illuminated
- Transmission shifts harshly in cold weather
- Delayed engagement when shifting from Park
- Transmission may overheat
Probable Causes (Ranked by Likelihood)
- Degraded TFT sensor with slow or inaccurate response Very High
- Contaminated transmission fluid affecting sensor readings High
- Intermittent wiring connection Moderate
- TCM calibration issue Low
Frequently Asked Questions
Can I drive with code P0711?
Drive short distances. Inaccurate temperature readings can cause the TCM to use wrong shift pressures, leading to premature wear and potential overheating.
Can old transmission fluid cause P0711?
Yes. Degraded fluid can leave deposits on the TFT sensor, affecting its ability to accurately read temperature. A transmission fluid change may help.
What temperature should transmission fluid reach?
Normal operating temperature is 175-225 degrees F. Temperatures above 250 degrees F accelerate fluid breakdown and transmission damage.
Mechanics Guide Step-by-step diagnosis
Step-by-Step Diagnostic Procedure
-
Monitor TFT sensor temperature during warm-up -- should rise steadily from ambient to 180-200F
-
Compare TFT reading to an infrared thermometer on the transmission pan
-
Check if fluid is dark, burnt, or contaminated -- this can affect sensor accuracy
-
Wiggle the sensor connector while monitoring live data for dropouts
-
Replace the TFT sensor if readings lag behind or do not match actual temperature
