Replacing An Output Speed Sensor As with the transmission fluid, park the car on an even surface and elevate it. Secure the back wheels with chocks, and go underneath the automobile. Then locate the ...

Typically the wiring harness connections for a 4L85-E are: the transmission (20 pin) connector, output speed sensor (OSS), input speed sensor (ISS), transmission control unit (TCU), throttle ...

The input sensor monitors the speed of the transmission's input shaft, which connects to the engine and supplies the transmission with its power, while the output speed sensor monitors the speed ...

The new TR6070 still has the same electronic reverse inhibitor, output speed sensor, 1-4 “skip shift” solenoid, a reverse lamp switch, and a transmission temperature sensor.

The transmission in my 2016   is intermittently violently down-shifting when slowing to a stop. What could the issue be here? Some Territories of around this vintage experienced a ...

Pickups may experience an intermittent loss of the transmission output speed sensor signal to the powertrain control module, potentially resulting in a temporary, unintended downshift into first gear.

So it assumes the output speed sensor isn't working, but we know the actual cause is the transmission's output shaft isn't turning.
