What happens when your transmission sensor goes out?

Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal.

What does it mean when your transmission sensor goes out?

If a vehicle is not shifting properly, it does not necessarily mean that the transmission itself is having a problem, because the problems could be caused by a sensor. Transmission sensors tell the vehicle when to shift and whether to shift up or down.

What is the name of the transmission speed sensor?

There are generally two speed sensors that work in conjunction to provide accurate transmission data to the vehicle’s powertrain control module. The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’s input shaft. The other sensor is the output shaft speed (OSS) sensor.

What happens when the output shaft speed sensor falls out?

The other sensor is the output shaft speed (OSS) sensor. If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.

Can a bad speed sensor affect shift timing?

Harsh or improper shifting. Without a valid speed signal from these sensors, the PCM will not be able to correctly control the shifting of gears within the transmission. This may cause the transmission to shift roughly or more quickly than normal. It’s also common that a problem with these sensors can impact the shift timing,…

What happens when a transmission speed sensor goes out of alignment?

If either of these two sensors falls out of alignment or experiences electrical issues, it impacts the operation of the entire transmission.

Can a bad sensor cause transmission problems find out?

If the vehicle is not getting the right signals from the transmission sensor, then you know it will not be able to shift. The car that is stuck in gear might have a damaged or poorly working transmission sensor since it will not know whether to shift to a higher or lower gear.

How to prevent a lost sensor and transmitter?

This orientation may help prevent a teeter-totter action at the sensor and transmitter connection which could lead to a lost signal. Apply steady pressure using a sterile gauze or clean cloth for up to 3 minutes.
