Ford Motor Company has improved its "Service Part Limited Warranty" coverage on both new and remanufactured gas engine and transmission assemblies, increasing the terms from three-years/100,000 miles to three-years/unlimited miles, effective Sept.1, 2010.

"This warranty enhancement exceeds the terms of most of our competitors, especially for transmissions," said Phil Armbruster, Ford's engine product marketing manager. "Ford also has no restrictions on the application of the vehicle, whether it is a private use, commercial application or municipality."

The new warranty terms apply only to gas engine and transmission assemblies sold on or after Sept. 1, 2010. Warranty coverage on Ford and Motorcraft transmissions and gas engines installed by the dealer begins on the date the repair order was closed. Warranty coverage for Ford and Motorcraft transmissions and gas engines replaced by an independent installer or fleet begins on the date of installation. Warranty coverage for over-the-counter sales begins on the invoice date. New and remanufactured assemblies still need to be registered with Ford in order to obtain warranty coverage.

The warranty coverage upgrade does not affect the diesel engine warranty, which remains two-years/unlimited miles for complete diesel engine and long block assemblies.

"The new unlimited-mile warranty component combined with Ford's quality, competitive pricing, outstanding availability, and no-risk core policy, provides a significant competitive advantage in the powertrain marketplace," Armbruster said.
