Official summary
Warranty Information Letter for Detroit New Service Replacement Engine SRT Update. While validating Standard Repair Times (SRTs) for Detroit's new Gen 5 engine series, DTNA discovered an error in a pre-Gen 5 SRT for the New Service Replacement Engine Program. As a result, DTNA re-studied the SRT and concluded that time for removing/re-installing multiple components (e.g., exhaust manifold/turbo, engine sensor harness, rocker arm assemblies, etc.) should not be included.

What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
