VEHICLE DESCRIPTION: HEAVY DUTY TRUCKS, SHUTTLE BUSES, TRANSIT BUSES AND STEP VANS EQUIPPED WITH ALLISON 1000 OR 2400 SERIES TRANSMISSIONS. THESE TRANSMISSIONS CAN EXPERIENCE PARK PAWL TO REAR COVER INTERFERENCE DUE TO AN OUT OF FLATNESS CONDITION.
THIS COULD CAUSE NON-ENGAGEMENT OF THE PARK PAWL WHEN THE TRANSMISSION SHIFT SELECTOR IS MOVED TO THE PARK POSITION, RESULTING IN UNINTENDED VEHICLE MOVEMENT AND A VEHICLE CRASH WITHOUT PRIOR WARNING.
ALLISON TRANSMISSION IS CONDUCTING THE OWNER NOTIFICATION AND REMEDY FOR THIS CAMPAIGN. DEALERS WILL REMOVE THE TRANSMISSION FROM THE VEHICLE, REPLACE THE PARK PAWL, AND REINSTALL THE TRANSMISSION IN THE VEHICLE. OWNER NOTIFICATION IS EXPECTED TO BEGIN DURING SEPTEMBER 2000. OWNERS WHO TAKE THEIR VEHICLES TO AN AUTHORIZED DEALER ON AN AGREED UPON SERVICE DATE AND DO NOT RECEIVE THE FREE REMEDY WITHIN A REASONABLE TIME SHOULD CONTACT ALLISON AT 1-800-252-5283 OR FREIGHTLINER AT 1-800-547-0712.
ALSO CONTACT THE NATIONAL HIGHWAY TRAFFIC SAFETY ADMINISTRATION'S AUTO SAFETY HOTLINE AT 1-888-DASH-2-DOT (1-888-327-4236).
