98 Windstar
I am looking for anyone who can help point me to the location of the computer for this 3.8 model. I have purchased a reman replacement, and I cannot find the thing. I have looked behind the glove box, the right kick on pass. side, the left fender by the firewall, behind console under stereo, under driver side dash. Must be a huge secret place I guess?? Any idea would be helpful. Thanks!

'98 Ford Manual says it's located "Behind RH side of I/P".
Open the hood and follow the main engine wire harness to the passenger side of the firewall and you will come to the PCM harness connector. The PCM itself is actually mounted inside the vehicle (on the other side of the firewall).

Ok, now that I have been through all that, I am still in need of some more advice. I replaced the computer, and that did fix two of the problems I was having. Now I am still having a problem with the transmission, which I believe is also an electrical issue. The tranny runs fine at first, then the speedometer needle drops down to 0 and it seems to downshift. After a couple of minutes, the needle goes back to whatever speed I am at and everything is ok. This happens at speeds above 30 (so far as I have experienced). Any ideas on the problem? I have seen people asking similar questions and have been given various answers on a couple of different sensors/computers that it might be. Thanks in advance to any help given.

Regarding the tranny/speedo issue, I would suspect a vehicle speed sensor (VSS) issue. The VSS is mounted on the tranny.

That's what I have been hearing about. Thanks for the confirmation. Now for the silly question. Where about is it? Drivers side, I imagine. I can find the shift linkage, but not the wires for the sensor. Maybe it is under the battery box or some place like that?

The manual doesn't tell me exactly where it is on the tranny. Look for a sensor that has a two-wire harness connector. The wire colors are Dark Green w/White stripe (DG/W) and Pink w/Orange stripe (PK/O).

Might have to do a bit of removal on the top side of the engine to reach it I am told. Been through this a time or two, and I am not looking forward to it at all. Looks like hours of fun. :/
