New Explorer guy with a question about speed sensors.

[pingman38]

First off I would like to say hello to everyone in Explorerland. I just came across this site tonight looking for anyone who has had the same problem(s). I am looking forward to getting to know you folks and learning as much as I can about my ride. I have a 96 XLT. Have had it for 2 years. My understanding is that the engine and tranny have been rebuilt. About 6 months after we bought it the O/D light begin to flash and the speedometer quit working. Vehicle would not shift into O/D, and would get a hard shift from time to time from 2nd to 3rd and from 3rd to 4th. Read some blogs and found out that these things had an issue with a speed sensor. We replaced the rear speed sensor i think, and everything worked for about a day. Then back to acting up. Come to find out there is a gear inside the tranny case that the speed sensor mounts into and this gear was stripped so the speed sensor was able to catch for a little bit until it wore down enough to quit making contact. Does any of this sound familiar to anyone? Any feedback would be awesome. Also about the same time all the windows intermittently quit working and finally went out completely. I've heard this is related. Thanks

Hi and welcome
The gear you are referring to is the VSS gear, and I think with your 2nd Gen Explorer, you have 4 speed sensors, 1 at each wheel.

Sorry about the tech question, I didn't read very thoroughly before posting.

You are by far, not the only one that has done that lol

Welcome to this forum! I've moved your thread to the transmission section. Check my sticky thread about speedometer gears for more information.

If theres a speed sensor at each wheel I have a 97 awd mountaineer, is there a way to get the speedometer working off one of these?
Thanks

There isn't a speed sensor at each wheel. One at each front wheel and one in the rear diff.

Your 97 has a speed sensor in the t-case for the speedo. I don't think there it a was to get it to use one of the others....

Bummer, so no known workaround if you got a tcase without the sensor?

Bingo!

Yuppers... The 97 needs the VSS signal off the t-case or trans. There *may* be some way to re-plumb the ABS control module's VSS output into the dash and make it work, but I would be surprised... There are a LOT of differences for the 98 model year (when they first did this), so it's unlikely the wiring would play nice, and an IP swap is almost out of the question thanks to the addition of the PATS system in 98...

Sorry...

Sounds like what I just got figured out on my 95...

I used this thread to give me an idea of what I was in for:

If that's your transfer case, t was a relatively simple and relatively cheap fix. You'll need to drop the drive shaft from the back of the transfer case, remove the VSS, take off the 30mm yoke nut on the back of the transfer case... pop out the seal and wiggle the 7 tooth speedo gear from the shaft...

Installation is the opposite, torque the nut at 150-180ft lbs.

I picked up all of the parts from the local Ford dealer... $2 for a new VSS gear (pink came stock on mine)... $9 for the new seal... and something like $10 for the the 7 tooth sleeved speedo gear.
