Flashing OD Light & Hard Shift on automatic Ford. Replace Transmission or install $20 Speed Sensor?

Flashing OD Light & Hard Shift on 1998 Ford Ranger automatic. Don't replace transmission without doing this first! How to replace Vehicle Speed Sensor (VSS) as cheapest first diagnostic. Replacing speed sensor also worked on 2006 Ford Ranger, 2000 Ford Econoline Van, & 2008 Ford Focus. Jump to fix at 5:05 .
Sometimes a new $20 speed sensor will fix a blinking OD light and "broken transmission". Sometimes it won't.
THIS VIDEO shows changing out the DIFFERENTIAL VSS (non geared, on top of the differential). There is also a TRANSMISSION VSS (geared, side of transmission). Either one can cause these symptoms. I think a Trans-VSS will affect the speedometer and the Diff-VSS doesn't.
Please add a comment below, let us know if it worked for you or not. Good luck!

Here's a great video we found AFTER the fix!
KUSTOMBLACK MOTORSPORTS does the same repair by replacing the SPEED SENSOR.
He has a much deeper voice than Grandaddy-o so you can trust him.

We can't find that awesome Ford video but here's the basics on checking automatic transmission fluid level. Okay - JONNY DIY isn't the most conventional and professional mechanic but he understands doing it yourself on the cheap. And you gotta appreciate his laid back style. Totally!
