Where is the Overdrive Speed Control Sensor located on a?

overdrive is simply the transmission output being faster than the transmission itself is turning , through the use of gear ratio , it is controled by the vehicle computer through calculation of input and output sensors and the vehicle shift/lockup solenoids..please rememeber to use the green accept button – thanks

What happens when the transmission speed sensor is lost?

If the signals are lost from the transmission speed sensors, the PCM will set a DTC and illuminate the Check Engine Light on the vehicle dashboard. It also can indicate an increase in tailpipe emissions surpassing acceptable limits for environmental contaminants from motor vehicles.

What are the symptoms of a bad overdrive switch?

Symptoms of a bad overdrive switch: Transmission won’t shift into overdrive; The driver is unable to disengage overdrive; Vehicle Speed Sensor (VSS) The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.

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 are the symptoms of a bad transmission speed sensor?

Symptoms of a Bad or Failing Transmission Speed Sensor. 1 1. 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 2 2. Cruise Control Does Not Work. 3 3. Check Engine Light Comes On.

When does the transmission go into overdrive?

Oh, 45 mph for example. The transmission shifts into overdrive and engine rpm drops below 1400 rpm. At this low engine speed, the transmission downshifts to 3rd gear, as designed, but then rpm goes up again and it meets one of the conditions to go into overdrive.
