    Abstract: Methods and systems for a hydromechanical transmission are provided. In one example, the method includes responsive to rotation of a portion of a mechanical assembly induced by cranking of an engine, blocking an output shaft of the hydromechanical transmission via joint engagement of a forward drive clutch and a reverse drive clutch. The method further includes pressurizing a hydrostatic assembly while the forward drive clutch and the reverse drive clutch remain jointly engaged, where the mechanical assembly is coupled in parallel with the hydrostatic assembly.

    Abstract: A method of operating a motor vehicle transmission includes measuring an operating temperature of the transmission, the transmission having at least seven torque transmitting mechanisms and at least three planetary gear sets, each planetary gear set having three gear members; determining if the transmission is in a park mode; determining if the operating temperature is below a predetermined threshold; if the operating temperature is below the predetermined threshold and the transmission is the park mode, implementing a shift delay mitigation process that includes engaging a fourth torque transmitting mechanism and a firth torque transmitting mechanism of the at least seven torque transmitting mechanisms so that they are locked to a ground to prevent a first gear member of the first planetary gear set from moving, which, in turn, prevents an input torque being transferred to a park pawl.

    Abstract: A shift-by-wire transmission system is provided. The system includes a gearbox that is configured and arranged to receive a rotational input and provide a select rotational output. The gearbox includes a plurality of gear assemblies that are operationally coupled together to provide the select rotational output from the rotational input. A shift assembly is operationally coupled to the plurality of gear assemblies of the gearbox to selectively change gearing of gearbox. An electric motor is operationally coupled to the shift assembly to activate the shift assembly to selectively change the gearing of the gearbox. A manual shift override is employed that is coupled between the shift assembly and the electric motor. The manual shift override is configured and arranged to manually disconnect the electric motor from the shift assembly and activate the shift assembly.

    Abstract: A method is provided for controlling a machine having a continuously variable transmission travelling on a ground surface. The method includes receiving signals indicative of a speed of the machine and an inclination angle of the surface on which the machine is travelling. The method further includes receiving a shift signal indicative of a desired change in a direction of travel of the machine. The method selectively activates at least one supplementary retarding device based at least on one of the inclination angle and the speed of the machine.

    Abstract: A transmission assembly for a self-propelled machine includes a transmission housing fitted with an input shaft and an output shaft, a so-called drive shaft linked to the input shaft by an endless belt transmission and, arranged between the drive shaft and the output shaft, transmission elements including a control mechanism for reversing the rotational drive direction of the output shaft, and a clutch control mechanism, the direction reversing and clutch controls carried by the housing being mounted respectively movable, one between at least three positions: a neutral position, a forward position and a reverse position, the other between at least an engaged position and a disengaged position. The direction reversing control forms, in the neutral position, an element for blocking the clutch control in the disengaged position, and the clutch control forms, in the engaged position, an element for locking the direction reversing control in the forward or reverse position.
