P0711 on Cadillac
Transmission Fluid Temperature Sensor Circuit Range/Performance
P0711 on Cadillac vehicles indicates transmission fluid temperature sensor circuit range/performance. Au7o has documented this code across 2 Cadillac models — most commonly on XT5, XT6. 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 Cadillac range from $200 to $4,000, 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 Cadillac by Model
Cadillac XT5(1 issue)
- 9-Speed Automatic Transmission Shudder2017-2024
The XT5 with the 9-speed automatic transmission develops a shudder during low-speed acceleration and gear hunting at highway speeds. GM launched a pilot program in 2020 for 2020-2021 models to address 9-speed defects. Transmission lockouts where the transmission will not shift at highway speeds are also reported. A June 2024 service update addresses clutch piston retaining ring issues on 2024 models.
Cadillac XT6(1 issue)
- 9-Speed Automatic Transmission Shudder and Hesitation2020-2024
The XT6 shares the same 9-speed automatic transmission issues as the XT5. Shuddering occurs especially when climbing hills before downshift, and low-speed hesitation is common. The torque converter clutch engagement causes shuddering when the transmission fluid degrades. GM issued a June 2024 service update for defective clutch piston retaining rings on some 2024 units. Transmission flush with Mobil 1 fluid has resolved the issue for some owners.
