I need to know which sensor of the two circle is the input sensor.

to make it short my transmission is shifting like shit and even to the point the car would not move forward at all.
96 accord CEL. P0715 is the code. (input/turbine sensor)

I went to the dealer and they dont know shit at all.
I just need to know which sensor is input so I can pay the dealer $110 for one.
this is the printout I got from the dealer. you may zoom in

first they didnt know anything about the sensor until a mechanic buying parts show them exactly what it was in their own computer but now ofcourse they dont know which sensor is what.

thanks
