PTO Configurations
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.
