How does a turbine shaft speed sensor work?
How does a turbine shaft speed sensor work?
The automatic transmission TSS (Turbine Shaft Speed) or ISS (input shaft speed) sensor provides transmission input speed to the transmission control module (TCM). The ISS sensor can be a permanent magnet (PM) generator or a Hall-Effect switch (Creates an on–off square wave signal that is used directly by the PCM/TCM for speed detection).
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.
Which is the output shaft speed ( OSS ) sensor?
The first is known as the input shaft speed (ISS) sensor. As described, this sensor is used to monitor the speed of the transmission’ input shaft. The other sensor is the output shaft speed (OSS) sensor.
How do you remove a transmission speed sensor?
Remove the mounting bolts to the speed sensor. Unplug the harness from the sensor. Note: The mounting bolts that secure the drive shaft to the rear axle may have hex, allen, or torx heads. Step 5: Use a flat tip screwdriver and pop out the sensor. Keep in mind that about one quart of transmission fluid will leak out when you remove it.

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.
