GM Transfer Cases: New Designs, Old Problems
New Venture Gear, a manufacturing arm of Chrysler Corp., was bought some years ago by Magna International, one of the world’s premier supplier of parts to automakers around the world. The division that produces the transfer cases has been renamed Magna Powertrain. GM introduced a new series of transfer cases in mid-2007, and these units are now coming into our shops for work. This will be the first in a series of articles regarding these transfer cases and going over identification, theory of operation, and overcoming some design defects and issues that are now showing up in the marketplace.
