Cadillac

This brand page lists the Cadillac drivetrain parts we hold: remanufactured transfer cases, remanufactured front carrier assemblies and two remanufactured 3.6L engines. Everything here is an exchange unit, so read the tag numbers in each listing before you order.

Buying and support

Transfer case listings carry tag numbers and Hollander numbers, for example 24256092 with Hollander 412-747, and 84154807 with Hollander 412-804. Match the tag on your own unit before ordering, since several of these differ only by input shaft design. Remanufactured units carry a 6-month limited warranty as standard. A 7-year / 1,000,000-mile extended warranty and a core fee waiver are available on request for qualifying remanufactured units, must be arranged at the time of purchase, and are not automatic. A refundable core charge may apply; call 216-250-6666 for the amount. See the remanufacturing process and the warranty page.
