So I just ordered my trans from Triple Edge Performance and I cant wait till it gets here. I got it loaded with the upgraded input shaft, 7/8 chain with the 3.29 ratio because I dont have access to any tuners in my area, High Performance Custom Built Stall Converter with Billet Cover 3200 stall speed, and the Meziere billett flexplate. Now the only part I'm missing is the passenger side axle, I'm trying to get a list of grand prix's that would have it from something supercharged because the trans are HD and mine is not. I know that both Monte's and Impala's need a Vin 1 and I cant find any in my area. I've hunted one down from a 00 Grand Prix GTP but I would like something a little newer because this trans is going to be worked and I dont really wanna blow my first axle in a couple days. Anyways any help would great thanks.

 

If I'm reading what you wrote correctly, then you're looking for what cars came factory with an HD trans in order for you to be able to find a passenger side axle, correct? If so then here's a quick list of vehicles that came with an HD tranny:

Pontiac Grand Prix GTP (as long as it's 97 or newer)
Pontiac Grand Prix GXP
Buick Regal GS (the newer ones with an L67)
Chevrolet Monte Carlo SS (04 with an L67, 05-07)
Chevrolet Impala SS (04-09)

Hope that helps and good luck with the new tranny. I hear great things about TEP and I will some day get a tranny from him.

 

Awsome thanks thats what I needed to know.
