A detent assembly for a transmission is provided including a transmission component, such as a shift rail, movable between a plurality of shift positions including first, second, and neutral shift positions. A contoured surface on the shift rail includes first and second recesses, respectively, corresponding to the first and second shift positions. A neutral recess is arranged between the first and second shift recesses corresponding to the neutral shift position. The first and second recesses, respectively, include first and second transition surfaces sloping towards the neutral recess with the second transition surface being steeper than the first transition surface. A detent assembly includes a biasing member and a detent member with the biasing member urging the detent member into engagement with the contoured surface. The biasing member generates a first work along the first transition surface and a second force along the second transition surface greater than the first work.

A method and system for independently controlling the steering of at least two wheels of a vehicle includes a steering angle sensor for sensing a desired amount of turning of the vehicle and a direction for the desired amount of turning. An electronic control unit, in communication with the steering angle sensor, determines a first desired turning angle for one of the wheels and a second desired turning angle for the other one of the wheels based on the desired amount of turning of the vehicle and the direction of the turning of the vehicle. The second desired turning angle may be the same as or different from the first desired turning angle. Independent turning mechanisms are coupled to each of the wheels and receives control signals from the electronic control unit for controlling the turning angles of each of the wheels independently of the other wheel.

A driveline assembly module includes a drivetrain assembly having drivetrain components such as a transmission and differential assembly integrated with a first and a second axle assembly. In one embodiment the drivetrain assembly is integral to the second axle assembly and a coupling attaches the drivetrain assembly to the first axle assembly. By mounting the driveline components, rigid axles, and suspension as an integral module, the components are replaced or serviced by replacement of the entire module. Thus, the individual mounting, replacement and servicing of the individual components, each having multiple independent attachment points, is avoided.
