UltraShift AW3 Auto Neutral Feature
All devices mounted on the vehicle that require Auto Neutral function from the Eaton UltraShift AW3 transmission must provide
an electrical interface with the transmission. A switch must be used to activate the Neutral mode of the transmission. This
feature uses pin 19 of the vehicle connector.
When engaged (switch closed), this feature causes the transmission to neutralize when the vehicle is stopped (i.e. stationary
PTO operation) and a transmission gear engagement cannot be selected. When disengaged (switch opened), normal
transmission gear engagement can be selected.
The Eaton UltraShift AW3 transmission must have an input signal from the device to activate this feature.
The input signal wire for Auto Neutral must be isolated from other Auto Neutral related circuits.
The ground connection must be isolated from local power device ground returns. Frame rail ground is not recommended.
