Non\-Safety Campaign – Vehicles with PACCAR transmissions may experience transmission service lamp activation, no gear engagement from neutral, and/or DTC 511 FMI 7 or 10 is set. Transmission software and shift calibration updates are available to resolve
- [A003](/bulletins/10182207.md), 2020-11-05, Service bulletin: POWER TRAIN; STEERING. PACCAR has determined that all Set Forward Front Axle \(SFFA\) models with the PACCAR 20K front steer axle and wide\-based tires have the potential to experience a shimmy or shake in the front axle. Wide\-based tires include any series tires with widths of 385 mm or higher. This is due a lack of friction in the current axle rotating components. Replacing the thrust roller bearing with a thrust washer assembly creates enough friction to eliminate the shimmy.
- [23\-003](/bulletins/10163419.md), 2019-08-02, Service bulletin: POWER TRAIN. Fix as Fail: Vehicles with Eaton Ultrashift Plus or Fuller Advantage Automated transmissions may display fault codes and/or have clutch release problems due to broken clutch levers. Resolution is to replace the clutch.
