Service bulletin SB 445

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

This Service Bulletin informs affected customers that customers may experience water migration into the transmission connector and harness on MY 2013 - 2017 MCI J4500 coaches, and that the transmission interface harness wire loom may wear due to stress or movement at the point of existing p-clamps or tyraps; that either condition may result in transmission codes, the PBSS (pushbutton shift selector) not shifting, or transmission failure; and that MCI will remedy the affected coaches at no cost to customers. This Service Bulletin must be implemented in conjunction with MCI Procedure 7-135.
