Freightliner alleges Allison using monopoly tactics

Freightliner is suing Allison Transmission in an Oregon federal court, charging that the General Motors Corp. division has monopolized or tried to monopolize the markets for automatic transmissions used in diesel-powered school buses, walk-in vans, recreational vehicles and shuttle businesses.

The suit alleges Allison is employing monopoly tactics such as exclusive dealing, full-line forcing, price discrimination and other practices.
