P0711 on Ford
Transmission Fluid Temperature Sensor Circuit Range/Performance
P0711 on Ford vehicles indicates transmission fluid temperature sensor circuit range/performance. Au7o has documented this code across 2 Ford models — most commonly on F-150, Transit Connect. P0711 means the transmission fluid temperature (TFT) sensor's signal is outside its expected range or not changing as the computer expects (range/performance). This sensor monitors how hot the transmission fluid is so the computer can adjust shift timing, torque converter lockup, and protect the transmission from overheating. A range/performance fault usually means the sensor is reading an implausible or 'stuck' value rather than being completely open or shorted. It can cause harsh or delayed shifts, no torque converter lockup, or the transmission defaulting to a protective mode. Typical repair costs on Ford range from $150 to $4,500, depending on the specific model and root cause.
Common Causes of P0711
- •Faulty transmission fluid temperature sensor
- •Low, old, or contaminated transmission fluid
- •Wiring or connector problems in the sensor circuit
- •Internal transmission overheating or restriction
- •Sensor reading stuck or drifting out of range
- •Poor ground or reference voltage to the sensor
- •Faulty transmission control module (TCM/PCM)
P0711 on Ford by Model
Ford F-150(1 issue)
- 10R80 10-speed transmission harsh/erratic shifting and torque-converter shudder2017-2023
The 10R80 10-speed automatic (introduced on the 2017 F-150) is widely reported to shift harshly: jerking, clunking, banging on the 1-2 and 2-3 shifts, hesitation, gear hunting, and occasional limp-mode with a 'Transmission Not in Park' or 'drive mode not available' message. Many trucks also exhibit a torque-converter lockup-clutch shudder felt as a vibration around 30-45 mph. Root causes traced in later TSBs include adaptive-calibration mismatch during break-in, CDF drum bushing migration, and valve-body bore wear/scoring. A class action (O'Connor v. Ford, N.D. Illinois) covers the defect.
Ford Transit Connect(1 issue)
- 8F35 8-Speed Automatic Transmission Shudder and Failure2019-2023
The 2019-2023 Ford Transit Connect equipped with the 8F35 8-speed automatic transmission experiences transmission shuddering, harsh engagements, slipping, and premature failure. Ford issued a Technical Service Bulletin for 2019-2021 Transit Connect vehicles built before December 20, 2021 with the 8F35 transmission addressing slipping and harsh engagement concerns. FordTransitUSAForum.com documents a 2019 Transit Connect XL 8F35 transmission failure at the 75,000 mile mark. Eng-Tips.com engineering forums discuss the inherent shudder issue in the 8F35 torque converter clutch. Earlier Transit Connect models with the 6F35 transmission also had recall campaigns (2013-2021 models). The transmission issues are exacerbated by commercial use patterns - frequent stops, loaded cargo, and city driving accelerate wear on the torque converter clutch and internal clutch packs.

What does P0711 mean on Ford?▼
P0711 stands for "Transmission Fluid Temperature Sensor Circuit Range/Performance." P0711 means the transmission fluid temperature (TFT) sensor's signal is outside its expected range or not changing as the computer expects (range/performance). This sensor monitors how hot the transmission fluid is so the computer can adjust shift timing, torque converter lockup, and protect the transmission from overheating. A range/performance fault usually means the sensor is reading an implausible or 'stuck' value rather than being completely open or shorted. It can cause harsh or delayed shifts, no torque converter lockup, or the transmission defaulting to a protective mode. On Ford specifically, this code is documented across 2 models.
What causes P0711 on Ford vehicles?▼
Common causes on Ford: Faulty transmission fluid temperature sensor, Low, old, or contaminated transmission fluid, Wiring or connector problems in the sensor circuit, Internal transmission overheating or restriction, Sensor reading stuck or drifting out of range.
