Service bulletin SB1468

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

Introduction of new transmission oil filler pipe assembly for vehicles with Cummins ISX engine and Allison WTB500® transmission. The new oil filler pipe removes possible stress on the grommet (part #11147825) that seals the oil filler pipe assembly to the transmission housing due to vibrations of the oil filler pipe assembly. The grommet prevents moisture and foreign material from entering the transmission housing and, in this way contaminating the transmission fluid. New parts are supplied as a kit. This service bulleting gives step-by-step instructions to install the improved oil filler pipe assembly.
