Method of transmission control in order to protect clutches from damage
A system includes a driveline, a user interface, and a control system. The driveline includes an engine, a transmission, and a clutch positioned to selectively couple the engine to the transmission. The user interface is configured to facilitate operator shifting of the transmission. The control system is configured to perform a transmission auto-shift procedure where the control system monitors engine speed of the engine for a period of time following completion of a downshift event with the transmission from a first, higher gear to a second, lower gear, compares the engine speed to at least one speed threshold, and automatically upshifts the transmission from the second, lower gear back to the first, higher gear (i) following expiration of the period of time and/or (ii) in response to the engine speed exceeding the at least one speed threshold during the period of time.

METHOD OF ADJUSTING A GEAR LEVER NEUTRAL POSITION
A vehicle includes a gear shifter operable to shift a manual transmission. An actuator is connected to the shifter and actuatable to bias the shifter to at least a first or second neutral position. The vehicle further includes a controller configured to bias the shifter, via the actuator, to one of the neutral positions based on a speed of the vehicle.

Shift lock protection
A shifter assembly for a vehicle includes: a body; a shift lock; and a shift lock lever that is supported by the body such that the shift lock lever is movable between a first position and a second position to cause corresponding movement of the shift lock between a locked position, in which the vehicle is immovable, and an unlocked position, in which the vehicle is movable. The shift lock lever includes a first end portion, and an opposite second end portion that is configured for contact with the shift lock. The second end portion is generally L-shaped in configuration, and defines an interior region that is configured to receive the shift lock to inhibit (if not entirely prevent) contact between the shift lock and other components of the vehicle to reduce any likelihood of inadvertent disengagement of the shift lock and unintended movement of the vehicle.

SYSTEM AND METHOD FOR TRANSMISSION WITH CREEPER MODE SELECTION
A mechanical creeper mode selection system for a transmission of a work vehicle is provided, in which the transmission includes one or more range modes having one or more range mode shift mechanisms each driven by an electrohydraulic circuit. The system includes a creeper mode selection lever movable by an operator to select a creeper gear range. The system also includes a sensor that observes a position of the creeper mode selection lever and generates sensor signals based thereon. The system includes a controller that processes the sensor data to determine a movement of the creeper mode selection lever and outputs one or more control signals to the electrohydraulic circuit to position the one or more range mode shift mechanisms in a range neutral mode based on the movement of the creeper mode selection lever.
SYSTEM AND METHOD OF CONTROLLING SHIFT MECHANISM FOR VEHICLE
A system and method of controlling a shift mechanism for a vehicle, includes a shift determination unit configured to determine information on a shifting stage of the vehicle according to an operation of the shift mechanism; and a control unit configured to receive the information on the shifting stage from the shift determination unit and to transmit a signal such that vibration is generated in the shift mechanism when the shifting stage switched by operation of the shift mechanism is a drivable shifting stage, wherein when a driver operates the shift mechanism to switch a shifting stage to a drivable shifting stage, a signal according to the corresponding shifting stage is transmitted to enable the driver to recognize the switched shifting stage and thus to prevent erroneous operation, ensuring driving safety.
SHIFTING DEVICE FOR VEHICLE
A shifting device in which a selected shift position can be confirmed easily, and which can be fitted easily in vehicles. The shifting device comprises: a restriction member that restricts a movement of a shift lever into a predetermined shift slot in a first shifting mode, and that cancels the restriction of the movement of the shift lever in a second shifting mode; and an indicator that indicates a first pattern when the first shifting mode is selected, and that indicates a second pattern when the second shifting mode is selected.
