You only have the one on the rear axle. You can try checking the connector, and see if it is corroded, or some such, but, if that doesn't work. Replace it.

Take a pic, because the only sensor towards the front of a 98 is the temp sensor.

Guys, sorry if it looks like I'm hijacking the thread. I thought it would be a waste of bandwidth to start a whole new one.

Regarding replacement of the sensor, part number 56028187AE on top of the differential:

should the new one just pop back in? Do you have to force it? Should I prep it with any kind of gasket? it looks like the red "O" ring (like in the pic) that comes on the part is the only seal. Is this correct?

any assistance is greatly appreciated.

Clean the area as good as possible before removal. Then be fairly gentle when pulling it out. Wiggle it from side to side carefully, while pulling it up. And lets not go where we are all thinking! LOL

You're killin' me.lol

I already got the old one out, but was wondering about installing the new one. After I've cleaned the surface/contact area, and tried to clean the connections on the male/female connectors, does the new one just pop in, and the red O-ring is basically the only gasket?

A little rear end grease wiped on the oring wouldn't hurt and would make it a little easier to pop in, but it's not a major requirement.

Default Tranny won't shift to third or stay in gear.

Hello. I have a 1999 1500, 5.9L V-8, AT 4X4, 130K miles.... I am having an issue with the truck not shifting(20-30MPH) unless I let off of the gas. Also when I apply a small amount of pressure to the pedal it shifts down as if I were trying to pass another car, I have to let off the gas again to get it to shift gears. I HAVE changed the tranny filter and fluid with no change. I am going to check to see if the Cruise works when I get home. Could this be the output speed sensor(tranny)? Thanks guys for any help or suggestions...

There is NO speed sensor on the tranny, only the sensor is on the rear axle. Odds are it's not bad unless you have the abs and brake lights on and your speedo is acting strange. I say look at the TV cable, make sure it's not broke at either end. And you can try adjusting it if it's not broke. Have you checked to see if you have any codes? You can try this for the codes http://dodgeforum.com/forum/2nd-gen-...code-list.html and this is the TV cable adjustment (in this thread) http://dodgeforum.com/forum/2nd-gen-...-in-trans.html

Ya that was replaced 7 months ago. What I meant was the sensor that the transmission has. i believe it is called the output shaft speed sensor located on the driver side of the tranny.

98's and up are not suppose to have one on the tranny. So I don't know what the deal is.

The sensor on top of the rear axle housing most likely. Is your ABS and Brake light on too,by any chance?

Did replacing the sensor on the tranny fix the shifting problem?

I am having the same problem. It starts up and shifts into gear and reverse normally my speedo works fine i have no lights on like the check engine or anything but it wont shift into 2nd gear or more unless i let it go down by itself then it will kick into 2nd or sometimes when i rev it 3k+ rpms almost 4 it will shift into 2nd then rarely 3rd. I changed the from speed sensor located on the transmission and it didnt really make any difference ..any suggestions on what it could be?

Afternoon all.

Guess what? I have the EXACT same issue Sounds like a popular one huh.

Well, I have a 1995 RAM 2500 8.0L (V10) and swear to God that I can't find a differential speed sensor to save my life...well at least my brother-in-law's life (as he's the one looking). We've found the transmission one but can't find the back one.

The symptoms I have is that I have no speedometer activity (none, stays at zero and the trip and odometer don't move) and the truck isn't shifting at highway speed (about 50-70 mph).

From the picture I saw on here, it looks like the sensor should be on the rear differential on the passenger side / rear, right? Is there a chance that it isn't located there? I have the Haynes manual and can't find any reference to any speed sensors other than the ABS (think there are two of those best I can tell by description) and the transmission speed sensor. I DO NOT have any ABS lights on or anything (could mean I don't have ABS...I just bought the truck 2 days ago, so not intimately familiar with it yet).

On the 95, the speed sensor for the speedo is on the output shaft of the trans, or T/Case. If you have RWAL, there should also be a sensor on top of the rear differential. Should be obvious..... follow the wires. If there are no wires..... you won't find the sensor either.
