2009 Jetta 2.5L P0715 Code: Input Turbine Speed Sensor Location and Replacement Guide

I own a 2009 Volkswagen Jetta with a 2.5L engine, and I'm currently experiencing a P0715 diagnostic trouble code indicating an issue with the input turbine speed sensor (A). The vehicle shifts roughly, especially when accelerating from a stop—after initial acceleration, the throttle feels unresponsive for several seconds, resulting in a loss of approximately 1000 RPMs before normal operation resumes. I understand that P0715 is a generic code commonly seen across various vehicles and typically points to a transmission input turbine speed sensor failure. The sensor is responsible for monitoring the rotational speed of the turbine within the transmission, which is critical for smooth gear shifts. While I’ve found conflicting information online about its location—some sources claim it’s mounted on top of the transmission case, while others say it's located inside the valve body cover or oil pan—I’m seeking clarity on where exactly this sensor is situated. I plan to replace the sensor myself, and I know the process is manageable once the correct location is identified. Any firsthand experience with this repair, especially for a 2009 Jetta, would be greatly appreciated. Thanks in advance for your help!
