Truck drives normally most of the time. The overdrive light will start flashing on rough roads or on smooth ones. If the rear tires break traction, the overdrive light will flash. I believe there might be a connection problem in the TSS.

Hello,

It looks like you have a transmission that is slipping, I would check the fluid level and condition and change it if needed, or the Turbine Speed Sensor is bad.

P0715 - Input/Turbine Speed Sensor Circuit Malfunction

Here is the location of the sensor so you can swap it out. Clear the codes when completed. Check out the images (below). Please let us know what happens.
