Ack So! I was right about this car! Someone got rid of this car because of a bad window regulator switch and a bad TR sensor! You know you can get a good deal on something with minor problems. Ha! I shouldn't feel good about someone else's lack of knowledge. Runs good now. MIL is off. No codes. Now I can do something else other than auto repair since the pressure is off. I'd really like to spend some time looking through a microscope. Microscopy. Sounds like a problem in the crotch area. Thanks for your support, gents.

Man! am I having fun. I got a code scanner which said there was an open in the TR sensor. I removed stuff on top of the trans, looked at C191 connector and found it was full of oil or AT fluid. Got a wrench and removed the 2 bolts holding the TR sensor to test it. Its easy to remove for testing. Bad sensor. It had an open just like the PCM said. I used RadioShack contact cleaner and Advanced Auto dielectric grease to assemble the connectors. I don't know what else. I got some good reference material if you're interested. "Automotive Technology," by Jack Erjavec 4th edition. That's the best 50 bucks I ever spent! Hope my problems are solved. I doubt it! This car has 250K miles on it. A/Transaxles are fascinating.

Sorry it took so long to reply Terry. I agree about guessing. I learned way back in tech school that guessing is a waste of time and material. That was back when almost all cars had carburetors! I don't know why I waited so long to learn about automatic transmissions! I'm looking at clutch packs and bands right now. Planetary gear sets. Torque converters. You know the Sturtevant brothers had a patent on an AT in 1904? That was about the same time that Packard invented the steering wheel and the Wright brothers demonstrated controlled flight! We live in a great country! Henry Ford had a few patents as well. Ford is our American heritage. I'm waiting for a set of insulation piercing leads for my Fluke meter to test that TR sensor that Ziyad told me to look at. Process of elimination. I'm thinking it's more a problem with the solenoids and the valve body. Have to wait see. Still haven't narrowed it down to whether the problem is electrical, mechanical or hydraulic! You know this car had some bad press. Funny about human nature when people sense something like blood in the water. I've taken it to a trans shop, no dice. I called the Ford dealer and they told me to get rid of the car! Ha! I don't care. I'm having some fun with mechanics. I don't believe all the bad hype. You take care Terry. Thanks.

Thanks Ziyad. I got hold of a Ford technical manual and have been learning many new things. Ford has a Rotunda trans tester which is very nice. I got the resistance values for the TR Sensor however, and can now test it with my VOM. Its a bit lame trying to be a DIY'er! going very slow, but it's fun. Thanks again.

I'm a DIY'er with past mechanic experience, way in the past. I'm wondering if anyone has seen this driveability problem. The hot trans is hunting, shifting between OD and kickdown speeds. Its fine when cold. It seems to be going out of gear when holding rpm and road speed with no load coasting. Under load on grades it pulls OK most of the time. I've replaced the Throttle Position Sensor. The Coolant Temp Sensor checks out. I haven't checked the Trans Speed Sensor because I don't know how. Looking at some troubleshooting guides I see maybe the filter is plugged, main control solenoids, and other things. Could it be a bad wiring connection, and where would that be? Ha! I haven't been under it much. I appreciate your help
