FUSE 28 KEEPS BLOWIN ON MY 2000 FORD TAURUS (DURETEC MOTOR) AND TRANSMISSION IS NOT SHIFTIN TO OVERDRIVE. THE FUSE CONTROLS THE HEGO SENSOR TRANSMISSION SHIFT SOLENOID,CANISTER VENT ,A/C CLUTCH RELAY,

My Taurus did that, too. Had to replace the trans.

every code I looked up related to selonoid, overdrive ,sensors in transmission , from codes I wonder if it moves at all or very badly.none of them an eazy or cheep fix.

The problem is that either the wiring harness going to the overdrive control motor has chafed and is shorting out, or the overdrive control motor is bad. Check out the wiring harness VERY carefully, if it's OK replace the control motor.

there is a solenoid for the overdrive in the transmission, couple hundred bucks to replace

Its most likely the vehicle speed sensor. Its on the transmission near the output shaft on the passenger side. Check the connection first, if it's good, change the sensor.

The heading says2000 taurus and 1999 taurus. I looked up the wiring for a 1999 taurus. Fuse #28 goes to the heated oxygen sensors and the canister vent solenoid. You have 2 oxygen sensors (green connectors)and 2 catalist monitors(blue connectors) that use this fuse for the heaters that are in the sensors. I would check these sensors to see if any of their wiring is shorted. I have seen in the past where oxygen sensor wiring would rub on a front drive axel and wear thru the wire insulation causing a short. You really need to look at all 4 sensors and their wiring closely for shorts. If they look ok then disconnect all of them and reconnect 1 by 1 until fuse blows again. Fuse #28 also powers the canister vent solenoid which is located under the trunk (under the car) in a black plastic housing (approx 1ft by 1ft). It is the only item with wires going to it. If you disconnect this and the fuse stops blowing then it is shorted. Also check the wiring to see if it rubs or is shorted anywhere.
Hope this helps

number 28 in the fuse box under the hood by the battery is a 15 amp Mini Fuse that run the HEGO Sensor Transmission Shift Solenoid, Canister vent, A/C Clutch Relay, Thermactor Bypass Solenoid. If your referring to the fuse box in the car under the dash it is a 10 amp fuse that goes to the Blower motor relay coil, EATC Logic
