Research notes

Caveats and conflicts (14)
  • Borg-Warner designed it; Tremec built it from 1998 per the article.
  • Borg-Warner/Tremec naming per source.
  • Tremec took over production in 1998.
  • Same T-56, builder name changes.
  • Borg-Warner name sometimes still used on the case.
  • Article lists both MZ6 and M12 for Z06; RPO naming inconsistent on page.
  • C6 Z06 (2006-2007) not listed on the T-56 page; confirm separately.
  • C5 article calls it Borg-Warner T-56; Tremec T-56 article uses Tremec name. Z06 box carries RPO M12 per T-56 article table. 2003 and 2004 not individually confirmed.
  • Quad Cab (2005+) was automatic only.
  • Early Vipers: Borg-Warner designed T-56, Tremec took over later; sources use both names. No Dodge service manual opened.
  • Same box is also called Tremec T-56 (Borg-Warner designed it, Tremec took over); the 2000 owner manual opened earlier did not name it. 1993-1997 vs 1998-2002 split follows the T-56 article tag table (ratios differ).
  • Row source text names it Borg-Warner/Tremec T-56; other Wikipedia page says Borg-Warner T56.
