The only alternative is to remove your transmission tail shaft and change out and match the internal gear to the correct speedo gear to compensate for your rear gear ratio.


That's much easier, but they are getting harder to come by evidently, as I saw some sites mention they only had a few left.

It seems simple enough to wire in the speedo correction but the 100 bucks is a little steep, especially when it was a struggle to get my wife to let go of 400 bucks for gears and install kit and trak lok rebuild lol

That's kind of crude.


Dine her, wine her and make sweet, gentle love to her.
And if that doesn't work.......................puppy dog eyes and begging usually will.

+1
The equalizing works for me too, but it can get expensive.
If I need a $200 part I know right away it's actually going to cost me $400.
That's the $200 for what I want, plus a $200 equalizer gift for my wife = peace at home.

I thought it was a bit expensive too, but when you look at the alternative I would rather spend the $100 than have to disassemble the transmission and mess with matching up the gears.


A lot of guys can just live with an issue like the speedo being off, but it would drive me up the wall.
Maybe we can find out exactly what they are doing with the electronics in it and you can fab one up?

Yeah, that's what I was talking about in the earlier post.
You have to match the speedo gear with the gear in the tail housing.


That's likely to cost more than the recalibration tool though isn't it?

Do some searching on how it works and see if you can find a drawing/schematic of the circuit(s) it uses.
You might be able to fab one up fairly easy with parts from radio shack.
