2000 Ford Taurus Question: transmission shift fuse keeps blowing on my 2000 ford taurus

To accurately answer your question, I need to understand your concern. There is no "shift fuse". Do you mean shift indicator or is your vehicle not upshifting? This vehicle is equipped with an electronic valve body which is commanded by the PCM. Do you mean the solenoid body power source?

My vehicle is not upshifting.The fuse/relay location # that keeps blowing is 28 in the power distribution box.

According to the owners manual, that appears to be a 15 amp fuse that covers the following components:
HEGO Sensor, Transmission Shift Solenoid, Canister Vent, A/C Clutch Relay, Thermactor Bypass Solenoid
You do not necessarily have an internal shift solenoid or transmission wiring harness issue -- although you may. You could have an oxygen sensor or wiring issue (HEGO), Canister Vent issue, AC clutch relay issue or thermactor bypass solenoid issue. I would recommend disconnecting all the other components one at a time - then replace the fuse and road test. If at the end you have all those components off line, and the fuse still blows you know you are dealing with a transmission harness or internal issue with the solenoids, etc.
Naturally, if you disconnect some of this, check engine warnings and so forth will come on (if they have not already...after all the fuse has blown...)...just keep doing your narrowing down of the concern and you will reach your answer.

Thanks DaveJHM, Thats what I will do. I will disconnect all those components one at a time and road test. Hopefully we can figure this out. I will let you know how it went.

I'm gonna guess here we're talking about the fuse related to shift interlock and the brake light switch...check to see if you have brake lights. If not, you could have a brake light switch and/or wiring connector issue.

I am experiencing the same problems as you are with my F-250. Did you find out the issue? I would really appreciate knowing. Thanks so much.

i had the same issue with my ford taurus i took it to the mechanic and the problem ended up being a short in the wiring it costed me a little bit of money for the labor but the problem was fixed pretty cheap they told me if i didn the narrowing down for them the total cost would only have been 95$ parts and labor included and i took it to a well know mechanic in kenosha wisconsin

My 2000 Taurus just started doing the same thing. I was on the interstate when mine blew.....I was lucky to still have an engine because it down shifted to second gear. I don't think it is my compressor because it has blown again when the AC was off. Did you have any luck finding the answer?
