Service bulletin SB26-053

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.

NHTSA's summary

Updated Service Bulletin for Eaton-Cummins Endurant Transmission. This bulletin replaces the version dated 05/18/2020. The link to the transmission service information has been updated. A new line of transmissions will be available in the Freightliner vehicles at the beginning of April 2020. The Eaton-Cummins Endurant is a manual transmission that uses compressed air for shifting and clutch actuation. It also requires a specific clutch assembly that is different than the current Eaton product line.
