Yes
If each the Grand Am has a 3.4L V6 and the Grand Prix has either the 3.1L V6 or non-supercharged 3.8L V6 I believe they do. That transmission is a Hydra-matic 4T60E.
Yes, it requires transmission, engine wiring harness and computer from donor car.
A grand prix gt un-supercharged will smoke a grand am gt, the supercharged gtp grand prix will destroy it.
no it will not. also the differential is hardened in the gtp supercharged engines but it will not even bolt up. if it were a gt and a gtp then it would fit, but you would need to change the differential to the gtp hd diff
Yes, as long as they are both 4T65E transmissions they will easily replace each other, everything is the same.
No
open the hood
The Aurora is faster. I have one myself. It has 50 more horses then a Grand Prix GT, and it is also faster then the supercharged Grand Prix GTP. Not much faster, but it is.
In my opinion, it isn't worth purchasing a car that has 189,000 miles. I would avoid buying a sporty vehicle like a supercharged 2000 Pontiac Grand Prix GTP 3800 as a first car.
I have a 2004 Pontiac Grand Prix GTP Comp G Supercharged, and it reccommends premium gas, but it does fine without it.
Yes
no it will not. most grand prix have 3.8l v6 while most luminas have 3.1lv6. the only lumina that has 3.8 is the ltz model. Also most of the 3.8lv6 found in grand prix are supercharged but if it wasn't from the factory then it wont be compatible
