With the light coming on in the instrument cluster the first thing that needs to be done is to have the fault codes read out/checked with a fully compatible scan tool or computer plugged into your model.Once this is done there will be at least one code set that will need to be diagnosed to then help locate and repair this issue here.This can be a fault with a shift solenoid or a sensor in the transmission possibly causing this fault needing replaced.
