What happens when a transmission position sensor goes bad?
A failing transmission position sensor may no longer send the right signals to the Powertrain Control Module, or PCM. Without signals from the position sensor, the PCM will no longer know when to shift the transmission’s gears out of park into a moving gear. Transmission shifts into the wrong gear.
How do you know if your transmission sensor is bad?
One of the most common signs of a bad speed sensor is abnormal automatic transmission operation. If the VSS is faulty, the transmission may exhibit symptoms such as delayed shifts, hard shifts, and limited gear operation.
