We have seen many changes in the companies that manufacture automobiles. Chrysler got married to Mercedes, the love affair didn’t last and now Chrysler is part of The Fiat Group. While Chrysler was paired with Mercedes, it chose a German-design six-speed for use in Chrysler vehicles. Thus we saw the NSG350, a six-speed manual transmission fitted to 2005-2008 Jeep Liberty, 2005-to-present Wrangler, 2004-2006 Chrysler Crossfire and the 2006-2008 Dodge Nitro, as well as some Mercedes ML models.
NSG is a German acronym for “new shifting manual transmission,” although you may also say NSG stands for “not so good.” This six-speed manual transmission has an integral bellhousing in the front case and as is common in European design is loaded longitudinally. Fifth gear is 1-1 ratio (direct drive) and sixth is overdriven, so be aware of this when you are diagnosing a problem.
The Jeep brand is one of the iconic names in automotive history. Created as a personnel carrier for the military during World War II, the brand has been owned by several manufacturers over the years and is now part of Chrysler Corp. The use of the original military vehicles by millions of American service members during and after the war created a market for the brand that is still very strong today.
