The case in point involveed Aamco, the nation's largest transmission repair business. Extended warranties offered by auto manufacturer were expected to significantly reduce future transmission repair business for Aamco's franchisees. This expectation of reduced business led many of these franchisees to push for a reduction of franchise royalty fees from 9% to 5% and to an expansion of their territories. A bitter conflict ensued, with the parent Aamco arguing that it needed the higher royalty rate in order to advertise and promote more aggressively in the face of the expected reduced prospects for future transmission repair business
