I just installed 3:73 gears in my 96 GT. Seems the Speedo is about 15-20 MPH off at speeds of 55-75. Any quick, cheap fixes known would be greatly appreciated.

Hmm, I think for the 96 he has a mechanical speedo so he will need to change the gear that drives it? I think...

But yeah, a quick forum search should reveal a wealth of info on this topic.

Mechanical Speedo, YES

It is a Mechanical Speedo. Not Digital. Where is the Gear? to correct this?

You might be right. Best to check at the Ford Parts Counter.

it should be the drive gears at the tranny that should be changed for those years i don't think that a tuner would do it

A more accurate way to correct the speedo can be done with a speedcal. Don't believe a chip can correct on '96-98 model years.

You can order the correct speedo gear from steeda or ford racing its about $20 for the gear and i believe it's located on the side of the tranny. Its a lot cheaper than a tuner.

i thought that anything higher than 3.73's couldn't be fixed, or is that with 4.10's? oh and wouldn't he have to change a gear in the tranny as well?
