I'm taking the Jeep in tomorrow for the brake recall and while its there I was gonna ask them to reflash the ECM for the bigger tires. They said they can do a "pinion factor adjustment" and that will fix the speedo but they don't think it will affect the tranny any. Then I read this thread and saw the someone paid $90 for the reflash and that there's the AccuPro available as well.

What should I do? Has anybody had this done from the dealer lately? Did it work? $$$$ ??? Should I just get the programmer and do it myself?

The Accupro works great. I have my speedo dead on now, and the tranny knows when to shift correctly now since the speeds are correct with the RPMs.
