PTO Configurations
WARNING
The transmission ECU contains configuration software for PTO mode. The default mode is set to “Countershaft PTO” operation
which also supports “Through-Shaft PTO” operation. If the application requires use of a “Split Shaft PTO”, the transmission ECU
configuration software shall be changed to reflect “Split-Shaft PTO”. The Eaton ServiceRanger tool is the recommended interface
for changing the configuration setting.

Auto Neutral Feature
An auto neutral feature is provided with this transmission which forces the transmission into neutral in all instances when the
parking brake is applied. This requires the OEM to “T” a pressure switch into the existing air line to the parking brake valve. Con-
tact the brake manufacturer for pressure switch requirements. The pressure switch output and return wires are connected to the
vehicle interface transmission ECU connector as follows:
