Re: Change gear ratio now gage is off
You need to change the speedometer gear in the transmission. Pretty simple, if you look on the tailhousing of the transmission you'll see a fat black cable going into the driver's side. The clamp that holds it in place comes off with a 7/16 wrench, and then the cable and gear pull right out. There's a little metal locking tang that holds the gear to the cable. Pull that off and the gear will come off. Bring that gear to your friendly local Ford dealer and tell 'em you need a gear of that same style, but with 21 teeth. This is assuming you're running stock outside diameter tires. Put that gear in, smear a little silicone around the outside of the piece that goes into the tailhousing, put the clamp back on, and you're done. Five minute job, and if you're skinny like me, you can do it without ever jacking up the car!
