Court rules in favor of Eaton

CLEVELAND - A U.S. district court judge ordered ArvinMeritor Inc. on Wednesday, Sept. 19, to stop making and selling truck transmissions with the Engine Synchro Shift system or variations of that system. Eaton Corp. claimed ArvinMeritor violated a patent it held.

ArvinMeritor appealed the ruling Thursday, Sept. 20. The ruling affected only one type of ArvinMeritor's transmissions.

Eaton, of Cleveland, claimed ArvinMeritor's Engine Synchro Shift transmission used patented Eaton technology that allows heavy-duty truck transmissions to shift without using the master clutch.
