use this instead of a new gear.........the "new" gears suck!

The gear you need is 1994-98-5speed-23tooth, or 1983-98-AOD-21tooth.
These gears wear out quick (6 months) and aren't accurate........
the Speed cal is what you really need....:smokin:

the 97 mustang 6 cycl is an AUTOMATIC trans.........And what is a SPEED CAL..........

thanks

Its a little box (2"x3") that wires into your spedometer wires in your center consol and it has settings inside it like a garage door opener (the teny tiny switches) you adjust them to your cars specs (3:27?) and the new gear (3:73) and plug it in.......and you use your existing speedo gear..........
You may have to have a "shop" install it? but it shouldn't be more than 50$ to do...
