Best I remember there's a clip. It's been a minute since I replaced my gear.

And now the next logical question: what am I looking for?
Once I get the car jacked up and supported and I locate the speedometer cable going into the T5 transmission… then what??
I just revisited LMR’s Speedo and drive gear calculator. According to it, with my stock T5 transmission I would need a 8 tooth drive gear and a 23 tooth speedometer gear given my 3.55 gears and 315/35x17 rear tires.

Ok, found and removed the drive gear. It’s the dark red one with clip, which is wrong for my car. I need the white 21-tooth. Assuming I have the stock 8-tooth driven gear in the tail shaft.
Ordered that and should be here Thursday. Fingers crossed it all goes well and my non-functioning gauges will work!

You need a "white" 23 tooth driven gear, not 21 tooth. All T-5's from 90 to 95 and all T-45's from 96 to 98 have an 8 tooth drive gear that is green in color. Shine a light into the trans where you removed the vss and you can verify what gear is there. 7 tooth is yellow, 6 tooth is black.

Is that with stock rear gears or mine,which is 3.55?

23 tooth driven is correct for 8 tooth drive and 3.55 rear gears.
Didn't we cover this some time last year?

So what if we did? Remember, you’re not obligated to respond, though I always welcome constructive feedback.
Or have I mentioned that before, too?

Not if the teeth are so worn it won't pick up at all. When I put my new one on, it lasted about two weeks before it started having issues again. Now, it doesn't register anything 99% of the time.

My maroon one doesn’t register anything, ever. Anxious for Thursday to get here so I can pop in the new 23-tooth gear.

Is the (next)replacement part I may or may not need the speedo cable itself? Or ??? I’m seeing speedometer cables online anywhere from $10 to over $100. But I don’t know which one or even if that is what I need altogether. I don’t remember what things look like on the back of the gauge cluster :-(

It could be the cluster itself.

Had the whole unit out and sent to an electrical engineer in San Jose that was recommended to my by members on this Forum. It was completely gone through and sent back in working order.
You do not have a speedometer cable. It’ll just be the two wires off the speed sensor.
How handy are you with a multimeter?

Pretty new to it, but I take instruction well!

I didn’t think that I have a speedometer cable because the only things coming off the back side of the gauge cluster are the 2 big “plug-ins”(whatever they’re called!)
So it can be a little tricky, but if we get the pin out for your gauge cluster, you can ohm the wire from the cluster down to speed sensor connector and make sure the wire is good. We would have to find the schematic though.
Also, you can pull the sensor out and hook a drill up to the end of the speed sensor. Turn the key on and spin the sensor to see what happens.
