Needing help in getting ccorrect ger for speed sensor?
 

I have in the past when switching rim sizes had to replace in the speed sensor of my American made vehicles. I just switched from the factory 14 inch wheels to a 205-40-17 wheels in my Miati. Is there a gear that I can change here to reflect the true speed that I am traveling at? Where canI go to get a breakdown of the transmission showing this?
