Well, you're going to have to edit the PCM somehow to let it know that the gear ratio has changed. You can do this via editing software like the HPTuners program I use or one of the handheld programmers they sell like the Crane PowerMax or Predator tuners.

Your computer will think that you still have 3.23 an will try to shift accordingly. You MUST change the computer so it knows what gear to use or you will be all over the place plus you speedometer will be inaccurate. Gas mileage will probably go down a ton.
If you need instruction on using your programmer download them. I bought a used Hypertech just to change the gear ratio.
