P0711 on Chevrolet
Transmission Fluid Temperature Sensor Circuit Range/Performance
P0711 on Chevrolet vehicles indicates transmission fluid temperature sensor circuit range/performance. Au7o has documented this code across 1 Chevrolet model — most commonly on Silverado 1500. 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 Chevrolet range from $150 to $1,200, 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 Chevrolet by Model
Chevrolet Silverado 1500(1 issue)
- Transmission Overheating from Failed 8L90 Thermal Bypass Valve / Cooler-Line Leaks2015-2022
Silverado 1500 trucks with the 8L90 eight-speed (and the older 6L80 six-speed) can run dangerously hot when the factory transmission thermal bypass valve sticks closed, so fluid never reaches the cooler — common under towing or heavy load. Sustained temperatures above ~220-250°F oxidize the fluid and cook the clutches and torque converter, accelerating the separately-known shudder/wear and shortening transmission life. Compounding this, the transmission cooler lines and fittings are a frequent leak point on these trucks, dropping fluid level and worsening heat. Owners towing in hot climates are most affected.

What does P0711 mean on Chevrolet?▼
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 Chevrolet specifically, this code is documented across 1 model.
