    Trans tune need help!!

    I am trying to get my Speedo correct and my trans to shift correctly but I?m not quite sure what to do I need the trans rev per mile and the vss pulse per mile. Any help is appreciated. It?s a 1996 obs with a 5.3 and a 4l60 it has 3.42 gears and tire size is 275/45r20

    If you can't figure it out, and you're able to see what's currently in the file, how is anybody else that can't see what is in the file (because you didn't post anything to look at other than a story) supposed to tell you which things need to be changed and by how much?

    Funny how accounts marked as 'banned' are still able to log in and do stuff on the site, huh?

    There is a gear/Tire calculator in HPtuners that does a reasonable job. Under file - edit.
