4.3.19 TOP2 SHIFT SOLENOID
The shift solenoid is used to command an automatic shift between the top two gears in an Eaton®
Top2 transmission. When the digital output is switched to power, the shift solenoid commands a
shift to the top gear position. When the output is not activated, the shift solenoid commands a
shift to the gear one lower than the top position. The correct transmission type must be selected
when this digital output is programmed. For additional information on Top2, refer to section 5.26,
"Transmission Interface."
Installation
This circuit is a high-side digital output. The Top2 Shift solenoid is wired to pin 3/8 of the CPC.
