  Vehicle Speed Sensor, Input Sensor, Sensor Overdrive Drum Speed

• Description:

  This is the genuine Ford overdrive drum speed sensor for the ten speed automatic transmission, cataloged as Sensor - Overdrive Drum Speed with the alternate catalog name Vehicle Speed Sensor and the Ford manufacturer note identifying it as ISSA, the Intermediate Speed Sensor A. It is the internal transmission speed sensor that reports the rotational speed of the overdrive drum to the transmission control module, which uses that signal to calculate slip across the clutches, time the shifts, manage torque converter clutch apply, and confirm that each commanded gear has actually been achieved. Verified fitment is 2020 through 2023 Ford Mustang with the 2.3L EcoBoost four cylinder, the 5.0L V8, and the 5.2L V8, with the ten speed 10R80 automatic. Drivers arrive at this part when the transmission starts flaring or slipping between gears, when shifts turn harsh and unpredictable, when the transmission drops into a failsafe or limp mode and holds a single gear, when the speedometer or gear display behaves erratically, or when a scan reveals input or intermediate speed sensor circuit and correlation fault codes. Because the sensor lives inside the transmission, replacement requires dropping the pan or opening the case per the Ford workshop procedure, so it is common to replace the pan gasket, filter, and fluid at the same time. Handle the sensor by its body, keep the pickup face clean and free of metal debris, seat the connector fully, and refill with the correct Ford specified transmission fluid. Clear stored codes and relearn adaptives after installation.
