Hello everyone,

My focus just started acting weird today at first I tough it was the Transmission, but after reading for 2 hours on the internet I am not sure what is the real problem that's why I want to ask here if I am not in the right forum please point me the right one and I will close this post.

The car starts fine Gears goes #1 in D 1 2 or R no bang it goes in gear fine. The Fluid does not smell burn it's still pinkish looking there is no leaks when I look at my normal parking spot.

The problems is that at 20Km/h the car does not want to shift it will rev high if I press more on the gas pedal but If I just let it "idle" to 20 it will shift eventually then sometimes will do the same at 50 2nd gear I guess.

After reading a lot of potentials problems I am quite confused some place talk about thing like PCM calibration or update or just bad wiring or full "tune up" could fix what I am facing or the worst possible case tranny failure...

So I am just seeking more advice from where to move from here what are my option to DIY or test to pinpoint the real problem.

Thanks

Best idea would be to get it scanned . Could even be the clutch packs worn out , but so many possible causes .

Vehicle speed sensor (VSS)
This may also be known as an output speed sensor (OSS). This sensor sends a varying frequency signal to the TCU to determine the current speed of the vehicle. The TCU uses this information to determine when a gear change should take place based in the various operating parameters.

Thanks for the reply I want to scan it but I am scared to ride the car at this point since the AT shifting is bad.

About the VSS I believe it would be located under the car in front ? is there any way to test it to see if it's that cause the problem ?

You can get problems with the wiring at VSS , worth a look .

Thanks I will check as soon as the rain stops, can it be tested with a multimeter
?

I'd like to know which speed sensor you are talking about? The two on the rear drums, or the one on the passenger side diff?

I ask because I am having somewhat similar problems with my ATX in my 2000 wagon, I have been told that the speed sensor can do it, but also the solenoids in the trans pan, and the only way to fix the solenoids is to bring it to a mechanic, and have him scan it, to be able to tell exactly which one or two are going bad, because I think there are a total of 6 or 8 in there?

" I'd like to know which speed sensor you are talking about? The two on the rear drums, "

They are normally the ABS sensors ?? Or maybe on your year of Focus you dont have them ?

The only speed sensor I know of otherwise is the one right near the passenger shaft on the diff.

That is the one we are talking about and suggested !!!!! Though I dont know if it's different on that year and being an automatic , probably not .
