I think I understand what you trying to do.
You pulled the P0715 code using whatever generic code reader you using which says "Input/Turbine Speed Sensor Circuit.
That code is generic.

So you called the $tealer and asked about that error and they told you what they did because on their systems it wouldn't show up that way.
Their diagnosis would show that code to be Transmission ......

What you need is a $tealer/indy with the proper diagnostic equipment.
