ABSTRACT:
A gear dependent manual modulation transmission control strategy is provided in a machine having an inching control arrangement so that during inching control operation the pressure of the fluid being directed to the selected clutches verses the displacement of the inching pedal can be changed relative to the selected gear ratio. This is accomplished by disposing a solenoid actuated manual modulation valve between a source of pressurized fluid and certain ones of the fluid actuated clutches and a controller operating to change the pressure relationship by changing the magnitude of the signal to the solenoid actuated manual modulation valve upon receiving a signal from a shift lever indicating a different pre-selected gear ratio.
