Dana has released a new Pneumatic Control Unit (PCU) 676467 and associated controller assembly 676651

parts replace the previous PCU 676403 and controller assembly 676632 for all production and service
requirements.
Note: When using the PCU 676467 as a service replacement for PCU 676403 (or prior), it will require a new
mounting bracket P/N 676644 and associated fasteners.
