Tranny issues...PLEASE HELP.

[Kansei]

it's the only thing plugging into the tranny on the back side.

I'd take a pic if I had my car

so that you don't have to take off the battery and battery tray, it would probably be easiest to see the speedo sensor from underneath the car?

i suppose.

is this it?
if so, it's plugged up there.

the speedo gear fit right onto your MSP LSD? I thought I remember reading that machining needed to be done.

mmm nice welds on the LSD

No, the LSD was machined to fit the speedo gear.

Thanks for the comment on the welds, I had my dad do them.

no, that's still on the front side of the tranny.. that's the neutral safety switch or one of the others.

ok. so if i were to get this pink gear or w/e...what would i have to do to get it to fit?

 

[Kooldino]

doesn't the speedo gear from the standard tranny need to be macined onto the lsd of the msp tranny? Someone recently posted pictures of this.

I know you have to do that if you use an MSP diff in a non-msp trans..

 

[Kooldino]

what about the msp ecu...would that change something?if i installed that instead of the lx ecu that i havE?

If in fact MSPs get their speedo reading from their ABS sensors, and you don't have ABS sensors...

 

[Dpwhitehead1]

I know you have to do that if you use an MSP diff in a non-msp trans..

but i don't have that..soo..what's the difference?

 

[Dpwhitehead1]

would that mean i'd need to change over to an abs type of deal?

 

[Kooldino]

the way we saw it..if the lx ecu isn't reading anything, maybe the msp ecu would read the sensor correctly.

Read what sensor correctly? The one that you don't have?

 

[Dpwhitehead1]

how do i know if i have it or not? that's the issue here. i don't even know where to look to see if i have it.. but it's a msp tranny, why would i not have the msp sensor..

 

[Kansei]

He has the sensor (speedo sensor), dunno if he has it plugged into his tranny or not though... the sensor just has no gear to get a reading from. CrazyCaker says his LSD was machined to fit the speedo gear, but I swear I read someone saying they machined the speedo gear (looks like it's plastic?) to fit on the MSP LSD for use in a non-ABS Protege. It's something I need to look into myself because I'll be installing an MSP LSD too.

MSP sensor isn't on the tranny, it doesn't have a speedo sensor at all. it just knows doing the computation for the ABS system. If your bellhousing has the spot for the speedo sensor and you have it hooked up, all you need is to get a speedo gear onto your diff somehow..

mother ******. i wish i knew where to look.. i didn't see anything just hanging before..sooo..i'm a bit confused.

 

[Kansei]

there should be three things plugged into your tranny. neutral position sensor, reverse sensor, and speedo sensor. the first two are on the front side of the tranny. The pic you posted with that sensor, it was either the neutral position or reverse sensor, don't remember which. The other one is on the backside more toward the starter/diff. if you can count three things plugging in, you have the sensor hooked up.

I know you have the sensor, I don't even know if it can be unplugged from the wiring harness. You had to have the sensor to have a working speedo before. You didn't swap the whole MSP wiring harness, did you?

As mentioned in this thread eleventeen times, you'd have to get your diff machined.

How many lug nuts do your wheels have?

technically I guess you could modify the speedo gear by cutting some of the plastic to make it fit, but it is not the "proper" way of doing it.

i found that also. they say nothing about having the lsd machined..just the pink speedo gear.pressed on..which he did evidently by hand...
