Progressive Shift Configuration
Progressive shift configuration can be set with the DDR or programming station and can be used
to force shifting. It is also useful to limit engine r/min in certain gears, to force shifting to a higher
gear. Use Spec Manager to determine values to enter.
Ratings can be selected with DDR or programming station. Selections are limited to ratings
available within the 6N4D group.
Top 2 (Eaton)
Top 2 can be set with the programming station. Two outputs are required - shift solenoid and
shift lockout. The transmission type is manual.
Transmission type can be set with the programming station only. Choices at time of print (may be
limited by the application code) are listed in Table 7-5.

Vehicle Overspeed Parameters
Vehicle overspeed parameters can be set with the DDR or programming station. Customer
decided parameters log vehicle overspeed codes. The parameter is typically set for +3 mph and +5
mph greater than the current vehicle speed limit; e.g. vehicle speed limit 65. Maximum overspeed
limit is 68 and maximum speed no fuel is 70. Setting both to zero disables the function.
Remember to review these figures if Fuel Economy Incentive is activated.
Vehicle Speed Limiting
Vehicle speed limiting can be set with the DDR or programming station. Requires VSS set to Yes.
