P0715 on Ford
Input/Turbine Speed Sensor Circuit Malfunction
P0715 on Ford vehicles indicates input/turbine speed sensor circuit malfunction. Au7o has documented this code across 2 Ford models — most commonly on F-150, Fusion. P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. Typical repair costs on Ford range from $150 to $4,500, depending on the specific model and root cause.
Common Causes of P0715
- •Faulty input/turbine speed sensor
- •Damaged wiring or connector at the sensor
- •Low or contaminated transmission fluid
- •Corroded or loose connector terminals
- •Open or short in the sensor circuit
- •Internal transmission wear or debris affecting the sensor
- •Faulty transmission control module (less common)
P0715 on Ford by Model
Ford F-150(3 issues)
- 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.
- 6R80 6-Speed Automatic Harsh 1-2 Upshift / Erratic Shifting and Lead-Frame Solenoid Body Failure2009-2017
The 6R80 six-speed automatic (2009-2017 F-150) is generally durable but is widely reported for a harsh, banging 1-2 upshift and erratic/flaring shifts, with thousands of NHTSA complaints. The internal solenoid body 'lead frame' (the mechatronic wiring carrier) can crack or develop failing solenoid calibration, and the adapt strategy struggles to relearn after service. The classic symptom is a 1-2 shift so abrupt owners describe it as a jolt that could 'knock a cup of coffee out of your hand.' Towing, worn fluid, and never-serviced 'lifetime' fluid accelerate the problem. It is a top transmission search for this generation.
- 4R70W / 4R75W Automatic Transmission Failure — No Reverse, Loss of Forward Gears, and Slipping1997-2008
The 4R70W (and later 4R75W/4R75E) 4-speed automatic behind the 4.2L V6 and 4.6L/5.4L V8s is prone to several high-mileage failures: a broken reverse (cast) band that produces a loud POP and loss of reverse; a cracked forward-clutch drum snap-ring groove on 2005+ units causing loss of ALL forward gears while reverse still works; worn overdrive band and clutches causing slipping; and solenoid-body/servo wear causing harsh or erratic shifts. Failures accelerate under towing/heavy loads and when fluid changes are neglected.
Ford Fusion(1 issue)
- 6F35 6-Speed Automatic Harsh/Delayed Shifting and Torque Converter Shudder2010-2019
The 6F35 six-speed automatic is prone to harsh, banging, or delayed shifts (most often 2-3 and 3-4) plus a shudder/vibration when the torque converter clutch locks up at a steady 40-60 mph cruise. Root causes are worn valve-body separator-plate O-rings and bores that can no longer hold clean line pressure, clogged/worn shift solenoids, and torque-converter clutch degradation. Many units develop symptoms well before 100,000 miles. A 2019 class-action lawsuit accused Ford of concealing the 6F35 defect on Fusion and Escape.

What does P0715 mean on Ford?▼
P0715 stands for "Input/Turbine Speed Sensor Circuit Malfunction." P0715 indicates a malfunction in the input/turbine speed sensor circuit of an automatic transmission. This sensor measures how fast the transmission's input (turbine) shaft is rotating, which the transmission control module uses—alongside output speed—to calculate gear ratios and command smooth, properly timed shifts. When the signal is missing, erratic, or out of range, this code sets. Symptoms often include harsh or erratic shifting, incorrect shift points, no speedometer-related transmission data, or the transmission dropping into a limp/fail-safe mode. On Ford specifically, this code is documented across 2 models.
What causes P0715 on Ford vehicles?▼
