Flittering speedometer

[racepics]

Ok gang, Had the tranny changed last March, however after it was put in the speedo needle jumps up and down and now the tranny is shifting funny and not downshifting when coming to a stop and while letting off the throttle the speedo drops to zero but when you get back on the throttle it flitters back up. We replaced the vehicle speed sensor and it still does the same thing.

maybe the new vss is bad.

this is on the ranger station.com but there can't be too much difference I'd think.

"Problem - "The speedometer on my '96 Ranger quits working sometimes."

Answer - From 1995-1997, check the VSS (Vehicle Speed Sensor) on the transmission/transfercase. Could be bad.

1) Turn off vehicle and disconnect the VSS cable.

2) Using a Digital Volt-Ohmmeter (DVOM), measure the resistance (DVOM ohmmeter function) between the sensor terminals on the VSS (not the cable).

3) If the resistance is 190-250 ohms, the sensor is okay."
