In order to get any kind of response for your question, it would be best for you to identify the specs of your car, year, etc., and what the issue is with your existing Swift gearbox (or codes, etc.) that is making you think you need to completely replace the gearbox??

 

Thank you, Bex ! Now I have a bit more info from my sister's car's service "project".

It is a SUZUKI SWIFT III (MZ, EZ) 1.3 (RS413, ZC11S), 2007 model. 68 kW / 92 hv, 1328cc.

Service shop said (to her) that the easiest is to order a replacement gearbox. So, now they have one, but for some reason they made a mistake and it turns out they have type ZN3, instead of P34. :-(

Therefore, there is a problem with missing "counterpart" for the speed sensor inside the gearbox to get the reading from. The sensor one could easily change over from P34 to ZN3, but...


So, either
1) they need to get a P34, which I heard is not that quickly available, or
2) I was wondering if the sub-assembly (with the ring with the teeth - called "reluctor", perhaps) could be changed over from P34 into ZN3 ?

Is it shown in this illustration - perhaps nr. 14 ? Or, where would it be ?

 

The diagram you are showing is for the front differential gear, as indicated in the diagram here (along with diagrams of the rest of the tranny):

. I don’t have the answer to your question (and found some of the same threads you’ve been finding on the forum to try to answer it….).

 

I believe that the reluctor ring may be mounted on the crank shaft…a speed sensor….and #12 here:

Suzuki

I hope someone else chimes in on this, as its beyond my knowledge base.

 

Bex,
thank you for your thoughts about my challenge. I am a newbie in all what comes to Swift. My sister's car...


Anyhow, it's just odd that there is clearly that sensor in the failed gearbox very near the differential (well, based on photos, this is what I think). But, that sensor isn't visible in the official diagrams on the gearbox brought up by the VIN of this car - like in the diagrams you've referred to in your post (and as in the ones in my post).

Could this sensor somehow be illustrated somewhere else in the drawings - where ? If it is odometer or speedometer, should I search among the electronics diagrams ? What do you think ?


Also, there is another thread that indicates a similar component/design btw. two other variants for Swift (1.3L) gearboxes ZN0 (with sensor & ring) & ZN3 (without sensor nor ring, just a blanc lid covering the mounting hole - that's the version they got for my sister, instead of variant P34).

See photos: https://www.suzuki-forums.com/members/bxr_85.263392/

And, to me it looks like the ring the sensor reads would be shown just within the differential sub-assembly, like that part nr 14 in the diagram.


Also, when you search for Suzuki part nr S-26121-62JE1 (part 14 in the part list of the diagram)

RING, EXITER

14

1

TYPE 1 JSAEZC11S00100152~ JS2ZC11S 65100451~ TYPE 2,3,4

you'll find e.g. these two illustrations that really resemble something like what a inductive sensor would need:

When I compare related variant part lists, it looks like some of the differential's parts were slightly different in two of these variants. Like the "27411", that ring and the bearing at the end, perhaps also the end sealing. But, it could well be that if these parts were changed over from failed gearbox to the replacement one, it just might do it.

Unless the left drive shaft were of different diameter than the bearings, of course, then also the bearings would need to be changed over, taken that their outer diameter would fit the cover. Or, something else that are not given proper measures was different...

Uuuhhh... I wish I had that car in my own workshop for actually checking these things out myself, and not like it being in a far-away who-knows-what car "service" shop having already the gearbox removed before actually verifying compatibility, first :-(

All opinions/angles greatly appreciated !

 

There are different types of reluctor rings which are used for different purposes - yes #12 is a reluctor ring used to determine crankshaft rotational position, #14 is a also a reluctor ring, used to determine the rotation speed of the differential assembly, other common places in automobiles you'll find reluctor rings are ABS wheel speed sensors, cam position sensors, cam angle sensors (in distributors), shaft speed sensors (in automatic transmissions).

The reluctor ring is just one part of a magnetic sensor used to determine the speed or position of something, usually something rotating.

 

Fordem,
thanks for this, much obliged. What would be nice to learn is how to actually get the critical part specifications, so that I could verify the possible differences/compatibility between these two variants, especially regarding those parts in the differential sub-assembly.

Would you have any idea where/how to get that kind / level of actual data, so that not all of this needs to be found out the old hard way of taking the parts out & measuring oneself ?

P.S. And, at one point I also need to make up my mind if I will actually want to go through the trouble of transporting that car to my place & getting seriously down in it. It's just that there are too many "car service shops" like this one that treats their customers like trash that make me so angry that I just can't bear it :-(

Generally speaking, that sort of data is not available to the end user, most vehicle manufacturers expect you to purchase the correct replacement parts rather than "mix & match".

In some cases, enthusiasts discover that parts can be interchanged by comparing part numbers in part catalogs, and then confirm by purchasing used parts - I've seen this done with Mitsubishi transfer cases to achieve lower gearing.

 

While this may not be helpful, if you can get the VIN for your sister’s car, and type it into the box on this page, it will bring up the factory parts catalog for the car:

Suzuki

Then go into the transmission page. As you’ve determined that the part (speed sensor) that you are actually looking for Is part of the differential, you will find diagrams and part numbers. It appears that the reluctor ring in the differential is a different part number, if the car is 2wd or 4wd. I don’t know anything about ZN3 or P34, or what the difference of them, and frankly do not even know if the diagram for the RS413 is specific for your sister’s car, as the catalog is not providing any dates, but just specifies RS413.

 

Just replied "in the middle of a discussion thread", which may not get much visibility, so please check this out for my report on a successful upgrading of a sensorless gearbox ZN3 into "a P34" with that odometer/speedometer sensor:

An amazing post. Thank you for your follow up and great photos. I’m glad that you were able to get this sorted, and hope that your sister is very happy with the repair. Threads like this give us all hope, that with the proper information, tools, patience and care (and some YT videos) few things are impossible. Very well done!!
