Who sells the aftermarket speedo gears for the T5? I need one calibrated to my 3.73's. I know someone posted the link but I can't find it...

That's where I got mine from. Both drive and driven gears.

Do I need a drive gear too? I was thinking I just need the one on the speed sensor

If your tranny was for a 3.08, it will have a 9 tooth drive gear, the trannies fro the 3.23 and higher rear ends have a 7 tooth drive gear.

Well I got my speed sensor out of a '89 v6 car, that had 3.42 gears, the tranny is out of an '85 Z28 that had 3.23's I believe.

On the tail shaft, the drive gear will either be pink or green. The 7 tooth gear is pink. You should need a 21 tooth driven gear to go with, assuming you have stock height tires.

I have the standard 245/50/16's.
So if my drive gear is pink then I need 21 tooth driven gear?
How come they only list a 19 and a 22?

Use the gears for the TH350, they're the same.

Oh that explains it...
These work also with the VSS rather than the speedo cable?
Sorry for all the questions, there website seems pretty confusing to me.

Can't answer that one for you. There are also differences in the non VSS bullets for the driven gear, mine had a different length shaft and wouldn't seal in the bullet. Paul found a bullet for me where he worked.

Hmm
This may be more of a challenge than I thought.. Thanks for the help though Al, and blue for the link.

I hate to be the one way off base here but since you're electronic VSS, won't you be looking for an SGI5 box or something?

edit; missed "be"

Ian, I'm confused. He already has the electronic speedometer, right? Shouldn't it be just a matter of dropping the right gear in the bullet where the pick-up is? Might be different if switching from cable to electronic, although, that Dakota Digital box can make things easier....

The T-5s in Firebirds and later Camaros used a gear with a pickup on it rather than the ring, IIRC. So you would be correct, yes. Very Happy

So now im confused, can't I just swap that gear? It came with the cable bullet, I swaped it out for the VSS out of a later third gen just fine.
