1354 w/o speed sensor?

[IZwack]

I bought a BW 1354 that was pulled from a 98 Ranger and wow its a bit different from the 1354s that everyone else on the board is putting in.

Where the speeed sensor is, there is just a hole - no sensor! I put my finger in there to feel whether or not maybe some one had just removed the sensor, but it doesnt seem like it. In other words, I don't feel anything for the sensor's gear to hook up to. Its basically like as if some one drilled about a 3/4" hole into a block of metal but did not drill all the way through - its just a 'well' on the surface of the t-case. Is the speed sensor's hole supposed to be like this?

there is one dark brown (or black) wire coming out about an inch or an inch and a half below where the speed sensor WOULD be. I have no clue what this wire is! I've read on the board that these single brown wires are usually for the electro-magnetic clutches but this is a manual t-case.

Has anyone ever used these later model 1354s ... or have any inputs on whether or not I can use this one on my X (98 sohc 5r55e)?

I bought this particular t-case hoping that it would have less mileage on it and hopefully less wear.

If I did swap this in but did not hook up the speed sensor, would I still be able to drive my X normally? I guess what I'm asking is, is the speed sensor on the t-case only used to tell whether or not theres "slip" between the rear and the front wheels? Or are they also used for other things like the vehicle's speedometer?

(sorry I don't have any pics, I'll try to borrow my friend's camera and post pics up if i can.)

In 98 they switched to a hall sensor for VSS (vehicle speed sensor) which means that there wouldn't be a gear inside, just a few dimples for the electromagnetic sensore to read. Since you also have a 98 your sensor should work with the case.

Are you sure this is a manual t-case. . it sure sounds like a 4405 if its got a brown wire coming out of it.

Yeah I'm possitive its a manual 13-54. the Tag says it is and it doesnt have a shift motor. There is also a plastic white sticker on the side of it from BW that also says 13-54.

Since you also have a 98 your sensor should work with the case.

So basically this t-case from a 98 Ranger is compatible with my 98 Explorer?

Depending on when I get home today, I'll try to get under my X to check out the 4405 (and hopefully snap some pics if its not too dark).


I was just thinking, maybe the reason why there is no VSS on this late model t-case is because of that VSS in the rear differential. I mean why have two VSS when they are saying the same exact signal? They're tied together by the driveshaft so my assumption is they are reading the same angular velocity.

This would be the optimal transfer case for you to swap in. I really don't understand the concern about a speed sensor. You don't have one on your current transfer case so you don't need one on the one you're swapping it. The 1354 will be tons better than the 4405 also.

i looked under my X this afternoon and it does have a speed sensor right under the rear output - or at least what i assume is the speed sensor. Its has 3 wires coming out a black plastic cover. Its held on by I think one bolt thats has about a 3/8" head.

Like the 13-54, my 4405 also has that one wire coming out of the case in the same exact location.

But the question still stands, is the t-case's VSS used only to tell whether or not wheels r going to slip (between the front and the back), or is it used for other things like the vehicle's speedometer? My assumption is 'no' since I think the speedometer is being feb by the ABS sensors. But this is only an assumption so please chime in if you have any more details or experience with these sensors.

If the VSS is used only to differentiate between slipping wheels, then I'll go w/o it and hope that my X will still run okay w/o it.

 

[Jefe]

OK, you're getting all these speed sensors mixed up. The 4405 has two small speed sensors to sense wheel slip. The rear sensor is under the rear driveshaft output (like mentioned), the front sensor is on the back of the case, hidden under the shift motor, in line with the front driveshaft. Now, in addition to that the 95-?? T-cases had their VSS in the output of the t-case. When they switched to using the ABS sensor as the VSS, they obviously did away with the VSS in the T-case. I thought that they switched over in '99, but perhaps it was '98.

So I guess I have to disconnect the speed sensors frome each front corner and the sensor at the rear diff housing and look at my speedometer?

 

[section525]

The speedometer only uses one sensor. That's the rear axle RABS/VSS one. The 4405 had other speed sensors inorder for it to be a Control-trac automatic 4wd dealio. With the 1354 you won't use any speed sensor but the RABS/VSS. Why would you disconnect the rear diff housing sensor?

Great! so basically what this means is i can still drive my X w/o problems even if i don't hook up the sensor on the t-case?

It just sounded fun so why not u know .

I guess I just have to friggin hook this thing up and see how it goes. I plan to do the swap like after the 19th of this month (March) cauz thats when I'll be on spring break (wooo rock on!) - and I still need to gather a few items before then (like the floor plate, linkage, and well just about everything else).

I did this swap just a few weeks ago. The only wires on your '98 1354 are probably the ones that are usually hooked up to the dash lights (4hi, LOW Range). I don't have any of that hooked up and its all good. But there is a thread about how you can actually get those lights to function on here somewhere.

Yeah I saw that thread and I'm not too particularly concerned about the indicator lights. I'm just more worried about the speed sensor. But if I can pretty much forget or ignore the speed sensor, then hopefully I'm good to go.

I am tempted to take apart the 98 1354 just to see what that one wire is connected to. But I dunno if I'll have the time before the swap.

 

[IZwack]

BTW who's going to listen to some1 that has Richard Simmons for their icon?

Grrrr

here is the 1354 i bought a few weeks ago:

does the "f87a" mean that this is an electrically shifted case? if it is, CRAP!!!

How many positions does the shift motor have? I can't see it clearly, but it looks to only have Low, Neutral and High, which would mean that the front output is electrically controlled by that one 'brown' wire. And if so, I can't beleive they still call that a 1354.

Now if it has 2 high, 4 high, Neutral and 4 low, then it is all mechanical like the older 1354

 

[Jefe]

Thats not true. VSS can be fed by any of the 3 ABS sensors. (at least by 2000 it could).

 

[IZwack]

GRR... GRRR!!! it has 3 positions.. A FREAKING AUTOMATIC!! EEEEP!

That's really too bad. If you try again in the future, look on the case itself. It will be stamped with a code that says it is a 1354.

AHAH i will try again, im trying to get one from detroit tomorrow as my brother is coming down next week from detroit - so he'll either drive it down or ship it down. ill call the shop tomorrow to make sure it IS a manual 1354!!
