The transmission speed sensor is crucial for calculating gear ratios and providing accurate data to the PCM; a malfunction can lead to improper shifting, damage to internal components, and issues with cruise control. Signs of failure include rough shifts, turning on the check engine light, and increased tailpipe emissions. Immediate diagnosis and repair by a qualified technician are recommended if any warning signs appear.

2. The transmission speed
sensor is used to calculate the
actual gear ratio.

3. There are two-speed sensors
that work coherently.

4. They provide accurate
transmission data to the PCM.

5. Here are the signs of a
malfunctioning transmission
speed sensor.

6. Without a valid speed signal
from these sensors, there will
be improper shifting.

7. This may cause the
transmission to shift roughly
or more quickly.

8. The malfunctioning sensor
can also impact the shift
timing of the gears.

9. When the transmission shifts
hard it can damage the
internal components.

10. The transmission speed
sensor plays a part in
monitoring cruise control.

11. When the sensors fail, the
PCM will send an error code
to the car’s ECU.

12. This will cause the cruise
control to shut down &
become ineffective.

13. If you see that the cruise
control is not responding,
then contact a mechanic
quickly.

14. When the signal is lost from
the sensors, the PCM will
illuminate the check engine
light.

15. It can also indicate an
increase in tailpipe emissions
crossing acceptable limits.

16. Proper diagnosing of the
problem should be done
immediately.

17. Contact a local mechanic
immediately if the warning
light is illuminated.

18. The above-mentioned signs
are an indication of
transmission speed sensor
failure.

19. Contact an ASE-certified
technician to repair the
sensor of your car.
