This page will focus on transmissions attached to all makes and models with 3800 engines NA or SC. These will of course focus on the automatic because that is all that came out on 3800 Supercharged and NA engines in a transverse fashion.
Top of the list because the engine is also the best choice for someone just wanting to get the right combination the first time.. See FAQ 3800SC / NA
