before you drop a pulley size please read the safely modding your 3800 thread in the general tech section. There is lots of info there and it might save you from having to replace your motor. Whatever you do, do not get a PCM from ZZP(erformance) as many motors have blown with this PCM installed at the time. Sorry to be not much help about the tranny's. They should be pretty much the same tranny but you would have to look at the tags and compare them to see if they are the same or not. Not sure about the solenoid, if it is the same or not... If you need a new tranny, the best ones for our cars come from Triple Edge Performance-they are a vendor here as well. Maybe Dave the trannyman could answer your questions for you. If you have questions, usually he is very willing to help whenever he can.
