Auto Neutral Feature
Electrical Interface Requirements
All devices mounted on the vehicle that require Auto Neutral function from the Fuller UltraShift ASW transmission must
provide an electrical interface with the transmission. A switch must be used to activate the Neutral mode of the trans-
mission. This feature uses pin A1 and B1 of the 30-way Push Button connector. See figure below for electrical interface
diagram.
Features

When engaged (switch closed), this feature causes the transmission to neutralize when the vehicle is stopped
(ie. stationary PTO operation) and a transmission gear engagement cannot be selected. When disengaged
(switch opened), normal transmission gear engagement can be selected.
The Fuller UltraShift ASW transmission must have an input signal from the device to activate this feature.
The input signal wires must be isolated from other related circuits.
