Speedometer trouble 2002 Ranger

[jeedee]

Can't seem to find any posts about speedometers after 2000. I've a 2002, 2 wheel drive, automatic. Speedo needle fluctuates, and is 4 MPH off....don't know how to recognize the speedo sensor on the output shaft, so I can test it. Many wires there...in a bunch, on the left side of trans case. Some more on top of the trans case, but non on the output shaft housing. Manual is of no help. Any assistance will be greatly appreciated......thanx.

OSS is the last sensor on the trans. Two wire plug. Your speedo signal should come off the sensor on top of the diff though.
