Description

For parts identification purposes, a Round Tag is affixed to the back of the rear case. Stamped on the tag are the Model Number (ex: NV271D or MP271), Assembly Number (8 digit number plus two letters), Transfer Case Build Date, and Low Range Ratio (2.72). In most cases, parts identification is pretty straight forward with the year and assembly number, but there are times we may need additional information such as the Vehicle Identification Number (VIN), engine, transmission, transfer case build date, or truck model.

Transfer Cases built in the Syracuse N.Y. New Process Plant have the NPG Logo and the legend New Process Gear Syracuse, New York in red plus wording to identify what each number signifies.

Early production transfer case assemblies from the Magna plant in Indiana have the New Process Gear red and silver build tag, but the words "Syracuse N.Y." are usually absent, The identification numbers are typically dot-peened instead of stamped with number dies.

Current production replacement cases built at Magna Powertrains New Venture Legacy Transfer Case plant in Indiana cases typically have the legend Magna Powertrain (top) Muncie IN (bottom) in red plus dot-peened numbers. Magna purchased the New Process Transfer Case production rights from Chrysler in February 2009.

OE Production Cases built at the Magna plant in Mexico are usually unfinished aluminum discs with just the identifying number stamped on the tag.

For Dodge and Ram, if the first digit of your transfer case assembly number begins with a R instead of a 5, your transfer case is rebuilt replacement unit.
