ok. used, v6 seems to be more expensive than v8 for some reason. also, i interchange data is very hard to find. I can tell you the major changes came in 03. switching 02 for 01 may work....and it may not. when I bought my tranny for my 03 the guy wanted to sell me a 06 tranny/engine combo for $1200 (no :q:q:q:q). problem is nobody could tell me if it would work or not. best of luck to you.
