Hello,

My 1.9 5 speed has a bit of an odd problem. It is dripping the oil from the transmission from the speedometer cable behind my gauges and ultimately on the floor and my feet. I've made sure the fluid level is correct, and replaced the sensor. The old sensor was dripping really bad, so I figured that was the cause. Well I've replaced it, and the problem is still occuring. What could be causing this and what would be the cure? Also would someone happen to have a photo of one installed? I'm not sure if the tab spaces the sensor or is supposed to go over the edge of the transmission.

Thanks,

Paul

I have two 2nd gen escorts with the 5-speed transmission. One of them did as your car is doing, though it was only noticeable on long drives. I used a rolled up paper towel wadded against the floor mat, which at least kept it from getting onto my shoes. Knowing that it was slowly losing fluid from the transmission, I got around to extracting the Vehicle Speed Sensor so I could check the fluid level - and replacing the sensor. It continued to drip out for a while; likely since the interior of the speedo cable was filled with ATF. I also used a couple of pipe cleaners to try cleaning out the 'vent' that is on the top of the transmission, under a little round cap. All I can say is that it doesnt do it anymore, even on long drives across the country. There is a rIubber "O" ring seal inside the VSS, and its not a replaceable item separate from the VSS.

That is a usual indication of either a bad seal on the Speedometer drive unit or over-serviced transmission ( as trans fluid expands as it gets hot, creeping up the drive cable housing and ending up dripping from the gauge cluster).

Overfilling the tranmission will blow the seal... and not necessarily right away. Fluid just needs to touch the very bottom of the gear. As the engine/metal/fluid heats up, it expands. These engines can run pretty cool so it might not blow until the peak Summer month. Messing with my transmission vent did nothing; it was fine. I was overfilling it.

It is coming past the seal in the speed sensor, wicking up the speedo cable. not a huge issue. usually replacing the speed sensor solves the issue. might take a while for all of the fluid that is in the cable to dissipate.

Hello everyone,

Thanks for the replies. So I got another sensor under the warranty and adjusted the fluid levels. I haven't installed it quite yet. I was wondering if it worth be while to replace the speedometer cable as well? It is a "special order" part apparently.

Thanks,

Paul

If your escort has over 200,000 miles on it, a new soeedo cable might be worthwhile. you need to pull out the cluster and get to the back side of it, to replace the cable. Its a little bit of trouble though, and I have not had any issue with a speedo cable on my escorts. I own 6 of them, all with well over 200,000 miles on them.
To remove the cluster you have to remove the bezel, and to remove that you need to drop the steering column. It sits in you lap while you are getting the cluster pulled backwards, far enough to undo its 3 or 4 connectors, and then the clip that hold the top of the speedo cable onto the back of the cluster.

As long as the ends at each side of the cable are fine, the cable should be fine. They don't really wear out and the aftermarket cut-to-length cables don't fit too well because the clamp-on end is too big.

Hello everyone,

So I got everything replaced again. Unfortunally the replacement sensor I got was the worst of the 3. Didn't even make it a ten mile drive before fluid started running all over my feet. Not dripping, but running. Does anyone have any ideas as to what I am doing wrong? I am seating the sensor correctly, have made sure the fluid barley touches the nub at the bottom of the gear, and made sure the speedometer cable is connected properly. If its the sensor itself, does anyone have any recommendations on a brand? I am currently fighting with the Napa brand one.

Thanks,

Paul

I see NTK listed, that is a pretty reputable company.

But nowadays who knows, maybe even they are just repackaging the same part all the brands import from the China National Animal Byproducts and Auto Parts Import and Export Corporation.

Hello,

Thanks for the relies. I was reading some other posts about the seedometer sensor which arose a question. I am using the red speedometer sensor. It was what was in the car when I purchased it, and it was also what was in the transmission I swapped in from the junkyard. I have 13 inch tires. Is this the right one? I saw some posts that suggested I should be using one of the other colors. Am I using the correct sensor, and could that be part of the problem?

I wouldnt bother concerning myself about the color of the gear. It wont have impact on the workings except for a minor change in the speed indication,
