    Pontiac GTO — Fifth generation, V-body / GMX281 (Holden Monaro, Australian-built captive import) (2004–2006)

    The fifth-generation GTO has one RPO code list per model year, 2004, 2005 and 2006, each a single page in GM Service Manual Online. The 2004 list shows the LS1 5.7 liter V8 and the 4L60-E automatic; the 2005 and 2006 lists show the LS2 6.0 liter V8 and the 4L65-E automatic, and the 6 speed manual M12 appears in all three. The NICB VIN manuals list the GTO as a single carline with no trim badges, and the 2004 manual shows a 5.7L V8 SFI aluminum engine for it. The 2006 list alone carries emission certification codes.
