P0717 Transmission Turbine Speed Sensor

This trany code must be approached with caution. If you remember, a trany code is not really a trany code unless it is accompanied by a trany failure symptoms. In this instance, this P0717 code comes with the following symptoms: engine cutting out, misfire and hard start after the engine is warmed up. So looking at these symptoms and if this vehicle is a FORD, try these tests instead: check the coil plugs which is the equivalent of spark plugs except it does not have any plug wires.

Start with the mileage and if the engine has over 100k miles, usually the coil plugs are worn. You can check it by checking the coil plug wells on the valve cover. If soaked with oil, the coil plug is normally shot and this goes the same for the valve cover gasket. Apparently, when the valve cover leaks oil, it is deposited in the coil plug well and starts shorting the coil plugs because of the contaminated oil.


when changing coil plugs, always replace them ALL as a set.
