Hi guys, im new to this site and have been doing some serious searching. All night last night and a couple hours today. I just bought a 2008 GXP and i know the trans will go, its not if its when. And when it does go i want to change to 3.29's. Now i know (from reading on here) that i should only need the 35/35 drive/driven gears, and not the actual final drive as thats what i have now. The car will remain stock minus a CAI, shift kit, and an Exhaust. It also will not be beaten on or drag raced but i do live in the mountains and my commute is pretty rigourous so i would like to do the 3.29's to help with that, itll probably help with fuel mileage as well... I really only have a couple of questions before i order anything.
1. Besides the 35/35 drive/driven gears do i need anything else???
2. Will the car be driveable with the stock tune untill i get it dyno tuned, about a week or two weeks after the rebuild. I know not to floor it as im sure the shift points will be crazy, but still driveable??? My tuner is close to 230 miles away.
3. Anything else i should do to the trans while it is being built to help it hold a little more power?
Thank you all for your time
