⚠️ Safety Warnings

Important safety information - read before proceeding

•Disconnect the battery before working on electrical systems.
•Allow engine to cool before opening the transmission or working on it.

Symptoms

•Check engine light illuminated
•Erratic or harsh shifting
•Delayed engagement when shifting into gear
•Transmission slipping or failing to shift
•Increased engine RPMs without corresponding vehicle speed
•Poor fuel economy

Diagnostic Steps

1
Scan the vehicle's OBD-II system for any additional error codes related to the transmission.
2
Inspect the wiring and connectors for the input/turbine speed sensor for any signs of damage or corrosion.
3
Check the transmission fluid level and condition; look for contamination or burnt smell.
4
Test the input/turbine speed sensor with a multimeter to ensure it is functioning properly.
5
Inspect the transmission control module (TCM) for any faults or error codes.
6
Clear the error codes and take the vehicle for a test drive to see if the P0715 code returns.

Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, transmission fluid, cleaning solvent.
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Inspect the Sensor and Wiring

Locate the input/turbine speed sensor on the transmission.
Disconnect the electrical connector from the sensor.
Visually inspect the connector and wiring for fraying, corrosion, or other damage.
Use a multimeter to check the resistance of the sensor (should be within manufacturer specifications). If the sensor is faulty, proceed to replace it.

3. Replace the Input/Turbine Speed Sensor (if necessary)

Remove the mounting bolts securing the sensor using a socket set.
Carefully pull the sensor from its housing; some fluid may leak out, so have a drain pan ready.
Clean the sensor mounting area with a cleaning solvent to remove debris and dirt.
Install the new sensor by reversing the removal steps, ensuring it is seated properly.
Torque the sensor mounting bolts to the manufacturer's specifications.

4. Refill Transmission Fluid (if needed)

If any fluid was lost during the sensor replacement, refill the transmission with the correct type of fluid as specified in the owner's manual.
Start the engine and let it idle, then cycle through the gears to ensure proper fluid circulation.

5. Clear Codes and Test Drive

Use an OBD-II scanner to clear the P0715 code from the system.
Take the vehicle for a test drive to ensure that the transmission operates smoothly and that the check engine light does not reappear.
