Hi could someone tell me if I can put a 2005 LS 3.0 transmission into my 2001 LS 3.0 with a bad trans? Thanks, Tim

Yes, you probably can put it in, but I doubt that you can make it work. The gen I and gen II transmissions are different. The gen II electronics won't know how to correctly control the gen I transmission. If you had searched, you would already know this...
