What's wrong?
The clutch assembly in the automated manual transmission on 2018 Mack Pinnacle (Cxu) and Anthem (An) trucks connects engine power to the transmission and releases it during starts, stops, and shifts. It lets the truck move off smoothly and change gears without the driver operating a manual clutch pedal. The system depends on the clutch parts holding their position under load.
On the affected trucks, an internal clutch component did not meet manufacturing specifications. That component can fail inside the clutch assembly. When it does, the transmission and clutch can no longer control power transfer as designed, which can lead to unintended vehicle movement.
Warning signs listed for this recall include increased vibration, noises, or rocking of the cab. Trucks with the related alert system can also give an audible warning, or show a display alternating between "AN" and the engaged gear, such as R, 1, 2, or 3.

What's the safety risk?
Unintended vehicle movement can increase the risk of a crash. Watch for increased vibration, unusual noises, cab rocking, or an audible warning.

Repair is free at any franchised Mack dealer.
