Just wanted to provide some confirmation that the 00-03 5thgen 4-Speed Auto Transmission will fit on the 2004 6thgen Maxima (4-Speed Automatic ONLY). I bought a fully built transmission from a 5thgen Maxima at a great deal. That was the only reason I went the 5thgen route. Otherwise, I would of just bought another 6thgen 4-speed auto tranmission (can be purchased for less than $350 used). The oil pan sits on the frame a bit but no big issue.
