I completely agree with the above post. Also with the 3800 you will get a different transmission. I believe it will either be the 4t60E or the 4T65E. Either one would be to your advantage. Both transmissions have a higher hp and torque rating than the 4T45E under the 3400. the biggest problem you will likely run into is getting halfshafts. But from what i hear it can be done with mating your current 3400 shafts to those from the 3800. Another thing is you WILL need the computer from the 3800 equipped vehicle. As mentioned it IS different. But its not all that hard to do. There are easily more parts for the 3800 anyway. If i still had my alero thats what it would have in it now.
