PO 715 is an engine code that states the trans is having a problem with an internal speed sensor.

Speed sensor is part of printed circuit board in the trans...MB part 140-270-11-61...$200. Takes a tech about 2-2.5 hrs to replace.

OF course that code MUST be erased from the trans computer as well as the engine computer.
