Tranny Differences

2001 Mazda Protege MPS
I have this little situation. I needed a new tranny for my MP3 so I purchased one last year but didn't get around to installing it til this year. Everything is fine with it except for the speedometer piece. (My speedometer and odometer is inop) I ordered a tranny for a 2003 Protege thinking it would be exactly the same except for a beefier shift fork (I am right) But all is not the same. On the MP3 tranny there is a plug that goes down into the tranny and connects to a plastic gear that is on the tranny. When you plug the wire in it, it control the speedometer and odometer. On the 2003 tranny, there is a plug on the tranny, but its a dummy plug, and when you take the plug out and look down into the tranny, there is no plastic gear. So even if I wanted to switch the module from the old tranny to this one, it wouldn't work because it doesn't have the plastic gear in the tranny anyhow. The place I ordered it from will not work with me, wont switch it out. Any suggestions? Anyone need a manual tranny with this type of hookup?
Here is what I read regarding the tranny differences:
sawp mazdaspeed trans into my pro5 n/o abs. No vss in speed trans! What can i do to get the speedo working! Do i need to get a abs system!!

The transmissions have two different part numbers. The speed does use the ABS speed sensor signal thru the ABS module for VSS instead of a sensor in the transmission. There is a dummy sensor in place of the real speed sensor on the Speed transmission but I do not know if there is a drive gear inside. Try pulling that dummy sensor out and looking down inside to see if there is a drive gear down inside. You might be able to use the speed sensor out your old trans???

I think you are going to find that is a bigger job then you can possibly imagine. I would seriously look into getting the right trans or an alternative speedo system. To install ABS you are going to need not only control module and hydraulic unit but also all of the brake lines, speed sensors, sensor rings on the axles and possibly axles not to mention the entire harness as I doubt the connectors for any of it is there. The ABS HU/CM alone is a little over $1300.00.
How about alternative speedo. A GPS not only gives your location but most give a pretty darn accurate rate of travel. If you could mount one in your dash so that it was easily readable while driving, you could use it for a speedometer. Just a thought.
What is so special about the Speed trans? It's just a 5 speed overdrive like the ordinary Protege.

well M speed trans has limited slip. NO wheel spin(just about).gears are longer and shifts so smooth.And the trans was $1500. may be i can just use the wheel sensors & wire it to the bcm?

Uh..no. Sorry but that will not work either. VSS signal is input by all four speed sensors to the ABS Control Module, processed and then sent out to the instrument cluster and PCM. The instrument cluster would not be able to process the A/C speed signal waveform into a useable VSS signal. That job is performed by the ABS module under the air cleaner housing area.

 
apparently you got yourself an MSP tranny and the junk yard doesn't even know it!

there is a white sticker on the side of the case with some numbers on it... those numbers will tell you what tranny it is

ALL protege trannys EXCEPT for the MSP ones come with a speedometer gear installed, regardless of ABS or not... on the ABS cars, it's just the "dummy sensor" like you said, but the gear is still in the differential... on the MSP (which all comes with ABS), it has none of this because it was cheaper for them to leave the gear out... like I said, all MSPs came with ABS so there was no need to install the gear
 
The guy saying the gears are longer is wrong. You sure you don't want the LSD?
You have 2 options:
1. Swap the tranny with someone else (plus cash, since the LSD is worth about 400-500$ on here)
2. Take out the tranny, have the LSD machined to fit a speedo gear (30-50$, plus a new speedo gear; ~25$ or so), and have it installed back. That would be a fair amount of cash though; it was about 400CAD for me to have that done up here, plus any costs for taking the tranny out. You could of course do this yourself with some patience and some tools, but that's your call...
 
lol.. wanna hear the sad thing fellaS??

the trans he bought, cost him 750.00

and he got quoted for an mp3 trans at something like 1350.00

im on the hunt for him.
 
$400? you got ripped off
it only costed me $80 to do it here!
4.5hours of labour including the machining to tear the the tranny apart (out of the car already) swap the LSD and a few other things and put it all back together. I think that's not bad. Something tells me 80$ was a "friend price"...
 
Ah well then you're comparing apples to bananas...I considered doing it myself, but figured I'd get it done right and pay someone reputable to do it.
 
How much would the wireing harnes for the speedo be off a MSP? I mean, if it is in fact a MSP transmission and it is built like that they must have a different hook up for the speedo.. Just an option i guess.
 
Ah yes.. i see... but if you only hook up the wires for the speedo and tack you dont really need to worry about ABS.. the car doesnt even know it doesnt have ABS so it wont faulty anything.. but i`m starting to think that my idea would be more of a pain in the ass then pulling the trans and installing that little plastic gear..
 
you don't get it do you? the ABS sensors is what makes the speedometer work! that's why the ONLY cheap way to get your speedometer working is to install the "little plastic gear"

it's NOT just about hooking wires up, you need electronics to make s*** work
 
Ah.. i obviously forgot that most cars with ABS use the ABS sensor to calculate the speed of the car and not the traditional method of calculating the it by the speed of the transmission... how ignorant of me...
 
I"m going to revive this thread :)

I just swapped the trans on my mp3 and discovered the same problem. Dummy speedo sensor and no plastic gear within the trans. I don't mind using my tach to know how fast I'm going, but I would like to have a functioning speedometer.

Is the MSP the only Protege with ABS and therefore doesn't use the traditional plastic speedo gear?

If so, I guess I now have an MSP trans w/ an LSD... lol. A pretty good deal too if so, since I picked it up for $425. But, I haven't noticed any difference in the traction with the front wheels since I installed the new trans. Someone plz clarify this for me.

*The MAN, I'm looking for your input :D

why??

there's a few different trans's out there.. the msp and some p5s read off of abs sensors(on the axles.)

the mp3 and reg proteges read off of a sensor that's built into the transmission.

sounds like the same exact thing happened to you.you either have a p5 trans, or msp trans.

k, so its probably out of a p5. The Throw out bearing was beefier looking than the one on my old trans as well. So My only options are installing a plastic gear for my old speedo sensor to use or to do another trans swap for one from a car that didn't have ABS?

lol, sounds like I have another Saturday of pulling out my transmission either way.
