Service bulletin PB_751

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

Depending on custom chassis configuration, the oil check level plug and sight glass may prove difficult to view and access on certain vehicles. Installing the 90-degree fitting and cap will allow easier access for checking fluid level while topping off the Integrated Pump Transmission (IPT) with fluid.
