P0715 on Jeep by model: symptoms, diagnosis and fix
Chrysler (FCA US LLC) recalled 2014-2015 Jeep Cherokee models built with the 9-speed automatic transmission because the transmission sensor clusters may have insufficient crimps in the transmission wire harness. With a bad crimp, the transmission can unexpectedly shift into neutral on its own. NHTSA classifies the resulting loss of drive as an increased crash risk, since the Cherokee can drop out of gear without warning while the driver is relying on it to keep moving. The Cherokee is one of several FCA vehicles sharing the 9-speed in this campaign; the 329,540-unit figure NHTSA lists covers the entire campaign across all of those vehicles, not the Cherokee alone. FCA's internal number for the recall is S55, and the owner notification began November 7, 2016.
Common Symptoms
- Transmission unexpectedly shifts into neutral while driving
- Sudden loss of drive / vehicle stops pulling even though the engine is running
How to Fix
The repair is free at any Jeep dealer. The dealer reprograms the Powertrain Control Module and the Transmission Control Module, and replaces the transaxle range sensor wire harness if it is found to be necessary. If you own a 2014 or 2015 Cherokee with the 9-speed automatic, enter your VIN at nhtsa.gov/recalls to confirm whether this campaign (NHTSA 16V529000 / FCA S55) is still open on your specific vehicle, then book the dealer visit. Chrysler customer service can be reached at 1-800-853-1403.
Sources for this issue (1)
The Mercedes-derived W5A580 (NAG1) 5-speed automatic used in WK and early WK2 Grand Cherokees is mechanically strong but suffers well-documented electronic and fluid-related failures. Faulty conductor-plate speed sensors and shift-pressure solenoids drop the transmission into limp mode (stuck in a single gear). Contaminated or degraded fluid (including water intrusion past the dipstick/fill-tube seal) causes torque-converter-clutch shudder, harsh or delayed shifts, and a knock on coasting downshifts. The 13-pin connector adapter can also leak, wicking fluid into the harness by capillary action.
Common Symptoms
- Transmission stuck in one gear (limp mode)
- Harsh, delayed, or banging shifts
- Shudder/buzz during light acceleration (TCC)
- Knock when coasting/downshifting
- Transmission warning or P0700-family codes
- Fluid leak at electrical connector
How to Fix
Scan for transmission codes; for limp mode inspect/replace the conductor plate (with integrated speed sensors) and any failed shift solenoid, and replace the 13-pin connector adapter/seal if leaking. Perform a full fluid-and-filter service with the correct ATF (MB 236.x / Mopar spec). Address water intrusion at the fill tube. Severe internal damage from prolonged shudder may require a rebuild.

Frequently asked questions
What does P0715 mean on a Jeep?
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 Jeep it is documented across 2 models: Cherokee, Grand Cherokee.
What are the most common causes of P0715?
The most common causes of P0715 are: 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). The specific cause varies by vehicle.
How much does it cost to fix P0715 on a Jeep?
Published repair estimates on Jeep range from $300 to $3,500 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
