Prior range sensor replacement wrong part? hard shifting?

[99sho-time]

Okay so everything on my car is doing fine. all monitors pass.

But i still battle a hard 1-2 shift and the occasional huge clunk when going slow. I recently got the tranny to shift much smoother by switching maf , tps, iac and new abs module, bad imrc and sticking breaks.. but still not there yet.

My tranny is rebuilt. and the shop could not figure out why. It has a brand new valve body.

however today upon questioning the neutral safety switch I noticed the part # was F6DP-7F293-aa on the one thats installed.

out of curiosity I browsed v8sho's parts list page and its says it takes a sw5198 with the alter part #'s being F5DP 7F293 AB and F5DZ 7F293 BA this range sensor is bigger in size.

I also notice that the connector is facing in a direction where it hits a bracket which make sit hard to remove possibly being another clue.

from my experience I know neutral safety switch/range sensors are important on taurus. because I think having a faulty one blew a transmission on my v6 tauri.

what do you guys think?

IIRC, your SHO is a 1998 right ?

Then the part # for 1998-2007 is F6DZ-7F293-A or F8DZ-7F293-AB. It's seems you have the good part. F5DZ-... are for 1996-1997

The connectors for 1996-1997 (8 pins) isn't fitting on the 1998-2007 (11 pins).

It's good to check his transmission range sensor sometime because of this : blue part can fall apart.


Your shifting probs can be related to a bad TPS. I just replaced mine this week on the SLO and it shift a lot better. I have came to think that the car have trans probs but no. Watch out the screws are hard to unbolt.

Wait but the range sensor in my car now is a F6DP-7F293-AA. And Mine is a 99. I think was an 11 pin.

What do you mean by clean your tps? on the inside where it inserts into the throttle body or did you mean the connector?

Ive been messing with tps voltages alot it seems to shift horrible if the voltage is lower than .999 or so. it's also brand new.

I unbolted it to replace it but I forgot that I replaced the TB on my Vulcain by the Duratech one on which it's not same TPS... I knocked it on something solid and twisted (small rotation) a little bit all 3 metal teeth (to force them to touch all the time the slots on the plug. (Yes, it was a plan B.) But only this, gave me a better feeling.

Sorry, I don't remember pricisely the voltage however...

I wondering tho if I should go ahead replace that range sensor. I guess I'll use the same part number? rockauto gives me many diff part # and styles lol.

 

[GEN 3 SHO FAN]

Very strange..., as we talk about this part, mine on the SLO (same part # on SHO) refuse to start the car yesterday. I took another one at scrapyard some month ago thinking about that. I don't know mileage but my SLO have it's original part and it have 162 k. Seems to be not superficial thing to do maybe after 150 k (I have some trouble with it since some months).

(If this part stop working, you will turn the key, heard the gas pump, the light will glow correctly but no starter noise at all. And you can have difficulty to turn the key to start the car before (I tought it was the the key that it was very used...). If the car don't want to start, put it into neutral and start the car.)

For parts, I don't remember where Rockauto put the neutral switch in their classment system (after verification it was electrical switch and relay). The others numbers are different makers. I will go with something identical in shape to F6DZ... (Personnaly, I will go to scrapyard and take 2 low mileage ones, then I will have 2 working motorcraft ($) and take all nuts coming with them if some are too rusted on mine.)

On my v6 tauri the radio would shut off when I put the car in reverse or the power steering would die on reverse to.
It was to late i blew that tranny. the range sensor might not throw a code there is a code for it i think but mine didn;t have any engine light and the car wouldn't move lol

I rode many years ago, that the GEM module can give some of these symptoms you described... It's the plastic box (black IIRC) just behind the fuse box in the bottom of the dash. Not sure there is a code for that thing. (Not sure too it's the same part # for SHO and SLO but the 2 have it there.)

 

[gamefanatic]

The module SHO Fan mentioned can be taken from any Tauri so you don't have to get it from a SHO. And yes it can cause many problems with the interior components.

Come back to put some precisions on the neutral switch.

I go to scrapyard today and remarked that there is also 2 models for the same years... The switch will be different if the car is with a floor shifter or a steering shifter. The one for floor shifter (SHO) is bigger (bottom).


Up : Column shifter is F8DP-7F293-AA/ ? (SLO 98-99)
Down : Floor shifter is F6DP-7F293-AA/F6DZ-7F293-A/ (the one you need for SHO 98-99).

Don't mess up with them, the nuts and the plug will fit but the speed position isn't the same.

It goes to show with our cars we need to be very conscious off the parts we actually need. because rock auto isn't always correct.
For instance nobody knew that my year was changed over to USCAR injectors.
on v8sho parts lists it states that the range sensor is (SW5198) (F5DP 7F293 AB ) (F5DZ 7F293 BA)
Yet at the same time some part numbers differ simply because they updated the parts such as for instance new motorcraft coils. the part number is diff because the boots are upgraded.

Alrighty so i changed the range sensor what an annoying little c-word it was. My shifts actually feel a bit better.

I'm wondering if i should drain the brain and unhook the bterminals? I really don't want because ive done a trilion times but if i have to i will.

UPDATE. Im gonna move to change the input shaft speed sensor. I was wondering i didn't see an output shaft sensor on mine anyone know if there is one on passenger side of the tranny?

If you want a clean start on the computer, yes, you should unhook one of the battery terminals for a few seconds or so.

I must admit that the shifts were a bit better after I changed this neutral switch on my SLO. With the age of our cars, I think we may do a 150 k maintenance list (check ups and repairs). Doing a list of parts that will soon broke at around 150 k (like starter, fuel pump, valve cover gasket, etc.) can be usefull at this time.

For the transmission, I never saw anything like that on the passenger side...

 

[GEN 3 SHO FAN]

As it had change the softness of shifts on my SLO, I wanted to change the one on the SHO... I checked the part # on mine and it's F6DP-7F293-AA (it's a 96). I have the exactly same number as 99sho-time (and according to the dust on it it's the original one)... I was checking to buy a new one but Rockauto sell it 100$ ?!? (75$ us).

I think I will go to scrapyard in the next days...
Wait, I have already one, the one on the photo ! Ha, ha ! Ford and his numbers management, very confusing !

Then it's appears that F6DP-7F293-AA / F6DZ-7F293-A (11 pins) are our numbers for all 96-99 SHO. I though first it was only for 98-99 but mine (96) have the same number.
