It could be an electrical issue, im not sure if your rig uses a cable speedo or electric. If electric it could be a poor or dirty connection. If its a cable it could be in need of a lubing.

our rigs use mechanical speedos, Im sure its just the cable! Do a search for speedo cable, there have been a few threads a while ago addressing it. Maybe others can chime in, but i would start with the cable

let us know what you find out!

if it is a cable, try unplugging the trans end and re-routing the cable into the engine bay. Now while holding that end as high as you can (so the cable is as vertical as you can get it) slowly drip a synthetic chain lube (I use mountain bike chain lube) into the cable.

If you unhook the cluster end aswell you can simply turn the cable with your fingers as you are lubing it. You should be able to feel and hear the resistance lessening.

mine took quite a few good shots of lube before it shut up. Very quite and pretty darn smooth now. Better then $100+ for a new cable.

t100 speedometer

When my speedometer broke I heard a snap, so there is a cable.. Before my cable snapped the odometer would not reset or turn properly, so I think it put stress on the cable. My tach, gas gauge, and temp gauge all need an occasional tapping to remind them to work. I think a bought a flood vehicle.

I am having trouble with my speedo cable as well...making some awful noises...anyone have some pics of where the connections are located? I have not looked behind the inst cluster yet, but I cannot find where it connects to the transmission...

2WD or 4WD? Auto or manual transmission?

Try giving that "Search this Forums" button a shot and type in speedometer. I'm sure it will find yer solution...

i have takin it off and lubed it and its better than it used to be but on just warm days(80 degrees) it doesnt work but as soon as it hits above 90 outside it works and im not sure about cold though

and i seriously doubt that small of a temp change can do this or that it has anything to do with this so im pretty sure its just a coincident.

Its pretty hard to lube it %100 unless you use my method and do it multiple times.

BAM,

This thread is very helpful, and I had already read this one...but it still doesn't have any pics or description of where exactly the cable connects to the transmission. I have a maintenance manual that I bought from advance auto parts, but it does not cover this...I do not want anyone to go to any additional work...I just thought there might be something already out there with pics...

Thanks for the assist! :thumbsup:

Here's the part number fer the 1993 T-100 2WD:
83710-34020

Looking that up on www.toyotapartsales.com I came up with this:

Item Number MSRP Core Price Price
8371034020 $55.13 $0.00 $39.77
CABLE ASSY, SPEEDOME

Check with ToyotaPartsMan here on the forums. He will probably git you a better price shipped than the dealer above.

BAM,

You are the man! Thanks a ton! I thought that might be it, and I assume that is an oxygen sensor going over to the exhaust...either way I was hesitant to disconnect it until I confirmed that was it! Thanks for the pic and all the "other" data! Hope I can help you out sometime! :thumbsup:

Yes...I believe that is the rear "post-cat" O2 sensor.

I replaced mine

I replaced mine a few months ago. It's a pain but can be done. Mine looked original and it went above the heat shields. The dealership wanted $75 for a new one, just the cable. I found it online for around $55 if I remember right.
You have the rip the dash down to the basics to get gauges out. I switched out my dash bulbs to red ones instead of the "green" ones while I had it out.
I attached a photo of the new cable and the dash 1/2 apart. I was going to take more photos but lost interest when I had to start moving heat shields. Once you get the old one all the way out the new one is easy. Those clips are hard to unlatch in such a small place.
