Service bulletin 56-002
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

Non-safety campaign: Vehicles equipped with an Eaton Endurant 12 speed transmission may experience transmission service lamp activation, no gear engagement from neutral, and/or DTC 511 FMI 7 or 10 is set.

| A003 | 2020-11-05. Service bulletin. 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 | 2019-08-02. Service bulletin. 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. |
| TIB23-002 | 2019-03-11. Service bulletin. Campaign: The clutch may not shift appropriately or the clutch may not disengage due to lack of torque on the clutch bolts. |
