On the gear ratio question. It should be posted somewhere how to program with HPT from 2.93 to 3,.29. Keep in mind that on a 2.93 HPT will show the ratio as 3.29 because it's referring to the differential not the overall ratio. 3.29 diff plus 1.121 sprockets = 2.93 overall ratio. It's basically change the ratio to 3.69 and reenter the tire size.. his auto and commit. But find that post and make sure I'm saying that properly.
On the trans swap. Lookup a writeup by me on how to put an external park neutral switch on a transmission with an internal switch for the gear selector and that will get the pcm to know what gear is selected. From there I think there might be one other pin swap that needs to happen to make it work. Check GMforums.com and a guy by the name of xtremerevolution I think is who posted it and found it on NEpontiac.org. Or look at the wiring schematics on the two years.
Looks like Xtreme had an 03, which is a different monster from this one. I though he may have gotten an 05 trans. Search on him and maybe you can find that pin stuff I'm talking about.
