P0717 on Chevrolet
Input/Turbine Speed Sensor Circuit No Signal
P0717 on Chevrolet vehicles indicates input/turbine speed sensor circuit no signal. Au7o has documented this code across 2 Chevrolet models — most commonly on Equinox, Traverse. This transmission code means the computer is receiving no signal from the input/turbine speed sensor, which measures how fast the transmission's input shaft (turbine side of the torque converter) is spinning. The computer compares this against engine and output speeds to control shifts and torque converter lockup. With no signal, it can't manage shifting properly, so you may get harsh or erratic shifts, no torque converter lockup, or limp mode. It is a no-signal electrical fault pointing to the sensor or its circuit. Typical repair costs on Chevrolet range from $150 to $4,000, depending on the specific model and root cause.
Common Causes of P0717
- •Failed input/turbine speed sensor
- •Open or shorted wiring to the sensor
- •Corroded or loose sensor connector
- •Damaged reluctor/tone ring on the input shaft
- •Metal debris on the sensor tip from internal wear
- •Poor ground or reference voltage to the sensor
- •Faulty transmission control module (less common)
P0717 on Chevrolet by Model
Chevrolet Equinox(1 issue)
- 6T70/6T75 transmission shudder, hard shifts & 3-5-reverse wave plate failure2010-2017
Equinox models with the GM 6T70/6T75 six-speed automatic suffer shudder, harsh or delayed shifts, slipping, and loss of reverse. A common root cause is failure of the 3-5-reverse wave plate, which can crack and cause extreme shudder when reverse is engaged and eventual loss of drive. Overheated/degraded fluid that loses viscosity accelerates internal wear. Failures typically appear between roughly 60,000 and 150,000 miles. Owners report bucking when engaging gear, failure to shift out of 2nd, and inability to engage reverse.
Chevrolet Traverse(1 issue)
- 9-Speed Automatic Transmission Shudder (9T65)2018-2025
The second-generation Traverse (2018+) uses the GM 9T65 9-speed automatic transmission that suffers from a shudder during light acceleration in the 25-50 mph range. The torque converter clutch chatters during lockup, producing a vibration that feels like driving on a rumble strip. The 9-speed also exhibits harsh downshifts, hunting between gears on hills, and delayed engagement from Park. GM has released multiple TCM software updates to address the shifting behavior, but the underlying torque converter weakness remains.

What does P0717 mean on Chevrolet?▼
P0717 stands for "Input/Turbine Speed Sensor Circuit No Signal." This transmission code means the computer is receiving no signal from the input/turbine speed sensor, which measures how fast the transmission's input shaft (turbine side of the torque converter) is spinning. The computer compares this against engine and output speeds to control shifts and torque converter lockup. With no signal, it can't manage shifting properly, so you may get harsh or erratic shifts, no torque converter lockup, or limp mode. It is a no-signal electrical fault pointing to the sensor or its circuit. On Chevrolet specifically, this code is documented across 2 models.
