Well long story short my fiance got a car passed down to her from her sis and its a piece. 2004 base model automatic trans. The engine is shot because the "mechanic" we took it to broke it. It was atleast runnin before we took it to him and now its not. Anywho, is the a engine we can upgrade to that bolts to the tranny? Also if we don't wanna upgrade just the engine what vehicle can the engine and tranny come out of that bolts in with no modifications?
