# Other TUCC\_MAY2025\_17

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

A potential concern has been identified on certain vehicles, where the transfer case clutch and / or All Wheel Drive \(AWD\) lock cannot perform as designed. This may show as a reduction in torque to the front axle during driving or as an inability to apply the AWD lock. A replacement of the transfer case control module \(TCCM\) and hydraulic pump is required.
